Hello from South Korea:) very traditional and not a typical house in Korea these days. yet I'm happy that the traditional technique is still in practice and you enjoyed it😊 that roof insulation was rice husk charcoal. I'm learning something new, too! Walls were constructed with clay or clay/durt mixture. No concrete stuff at all except for the white top surface, I think (it was limewash). You can pressure wash and the walls can be taken down😅 but that's the traditional way. I believe the house is not fasten to the ground. Gravity only, and moisture prevention method is the square piece of rock isolating wood from the ground moisuture, traditionally. I'm pretty sure that floor of this house is heated via water pipe installed in the concrete slab, making it kinda moisuture proof during the cold season? Real traditional houses were constructed with a system that circulated hot exhaust from fireplace under the floor usually built in the kitchen as cook/heat dual purpose or separately for the purpose of heating the house. Floors were constructed with clay and rock slabs called "ohn-dohll" (sorry for miss spelling, ondol is the right term) which literally means "heat stone" which help regulate and sustain heat for a long period of time once heated. Those are replaced with water boiler system these days. I'm not a construction worker, so not sure what wood or treating technique was used. This is some of the answers I can give you! Long time subscriber of ur channel and love the stuff you and your son present to the world. Watching the construction with your reaction at the same time was a dang good end-of-year present. Thank you and happy new year🎉
The white coating looked like limewash, which makes me wonder how well it would perform over the brown plaster, as when lime plaster dries, it's much harder than the mud-based plaster.
The only thing that bothers me about using gravity-only to hold the posts on the foundation is that they're right up against the edge. If any shifting does occur... one side or the other has nowhere to safely shuffle to. I know people wouldn't like how it looks, but I would seriously want a few cm of extra foundation to allow it to adjust over time without collapsing.
선생님. 안녕하십니까? 저도 선생님의 구독자로서, 선생님의 여러 비디오 클립들에서 서구목조건축에 관해 많은 것들을 배울 수 있어서 감사했습니다. 또한 목공과 관련한 여러가지 유용한 팁들도 좋았습니다. 그런 제가 선생님께 우리 한국 전통건축에 대해 말씀드릴 기회가 생겨서 아주 많이 기쁩니다. 1. 한국의 전통건축현장은 '치목장'이라는 곳에서 나무를 재단하고, 건축에 필요한 각종 부재를 만드는 과정으로 시작합니다. 모든 건축과정을 총괄하던 '도편수'가 현장의 총감독이었던 예전과는 달리, 현재 '도편수'는 건축의 목공과정 즉 구조물과 창호까지의 과정만을 총괄해서 감독합니다. 그리고, 창호는 전통적으로 창호와 가구를 전문으로 만들던 소목장들이 전통창호를 만듭니다. '치목'이라는 과정은 원목(원래는 한국 자생종인 육송이나 요즘은 북미산 더글라스 퍼를 주로 사용합니다.)을 재단하여 치수와 각종 부재에 맞게 장부의 자리를 파고 깍고 다듬는 과정입니다. 한국 전통 건축과 창호, 가구의 제조방식의 기본은 짜맞춤방식입니다. 기둥과 연결되는 창방, 도리, 대들보, 동자주, 중보, 대공 등등의 부재를 정해진 자리에 암,수의 장부를 파서 짜맞추는 방식이 한국전통목공의 기본입니다. 선생님께서 보신 부재들은 전부 '치목장'인 공장에서 미리 목수들에 의해 가공된 상태로 현장에 운송된 부재들입니다. 2. 한국전통가옥인 '한옥'은 기본적으로 떠있는 집입니다. 지면에 고정시키는 기둥을 박고, 기둥에 고정된 장선을 깔아서 내력벽체를 통해 하중을 받치는 서양의 방식과는 많이 다릅니다. 한옥은 다진 땅 위에 주춧돌을 놓고 주춧돌 위에 기둥을 세우는 떠있는 집이며, 기본적으로 지붕의 하중을 서까래와 보 그리고 기둥을 통해 받치는 기둥구조입니다. 그리고, 한옥은 긴 처마선을 가지기 때문에 기둥이 비에 젖어 썩을 일이 없습니다. 보통 벽면에서 1m 이상 떨어진 처마선을 가진다고 생각하시면 됩니다. 그리고, 한국은 흰개미로 인한 목조주택의 피해는 미미한 편입니다. 한옥의 모든 부재는 원래 칠을 하지 않습니다만, 요즘은 Oil Stain을 칠하기도 합니다. 하지만, 한국의 기후 때문에 기둥이 썩는 일은 거의 없습니다. 기둥이 썩었다는 것은 도편수가 처마선을 제대로 잡지 못했다는 뜻이기 때문입니다. ^^ 원래 한옥의 지붕은 습식지붕입니다. 서까래 위에 지붕판('개판')을 깔고, 치목을 하고 남은 나무의 잔재를 올리고 그 위에 황토와 석회를 섞은 흙을 덮고, 유약을 발라 구운 기와로 마감을 하는 방식이 전통적인 방식입니다. 그래서 지붕무게가 집을 누르고, 기둥이 주춧돌을 벗어나지 않습니다. 하지만, 요즘은 지붕의 단열문제, 기와의 파손이나 지붕 시공시 결함으로 인한 누수와 서까래 부식문제, 기와기술자의 기와시공의 비용문제 등등으로 인해 건식지붕을 많이 하는 추세로 넘어가고 있는 중 입니다. 3. 한옥을 포함한 한국의 모든 주택은 '온돌'이라는 보일러시스템을 통해 난방을 합니다. '온돌'이란 바닥의 돌을 데워 방바닥을 따뜻하게 해서 방을 데운다는 뜻입니다. 요즘의 한옥은 기본적으로 800mm 콘크리트 기초를 하기 때문에, 기초 공사를 할 때 바닥배관 공사를 미리 해둡니다. 지금 보신 현장은 기본적인 구조만 한옥의 형식을 따고 있고, 벽체는 패널라이징 방식으로 미리 만들어 온 벽체를 시공하는 방식입니다. 이건 현대적인 방식이죠. 원래는 저런 형식의 벽체를 현장에서 만듭니다. 벽체를 마감한 방식은 전통방식의 현대화라고 말씀드릴 수 있겠습니다. 황토와 시멘트 몰탈을 섞은 황토몰탈로 내벽을 마감하고, 외벽은 황토와 석회 시멘트 몰탈을 섞은 재료로 미장을 하고, 소석회 미장으로 마감을 했습니다. 지붕의 단열재는 쌀겨를 태운 왕겨숯이었습니다. 자주 쓰이는 재료는 아니고, 한국에서 친환경 단열재로 나온 실험작 중 하나라고 보시면 됩니다. 4. 저는 이 비디오 클립이 한국의 건축시장의 단면을 보여준 비디오 클립이라고 생각합니다. 친환경과 패시브 주택 그리고, 서구식 목조주택이 보급되면서 한국에 들어온 prefab공법등이 한국의 단독주택시장과 전통건축에 어떤 영향을 미치고 있는지를 잘 보여주고 있다고 생각합니다. 친환경 단열재로 쓰인 왕겨숯이나, 패널라이징된 벽체들, 생략되어 모양만 남은 '목귀연' 같은 것들을 보면 새로운 것과 없어지고 있는 것들의 대비가 선명하게 드러난다고 생각합니다. 아! 박공의 연결부위에 장식으로 박은 철물은 '지네철'이라는 이름을 가지고 있습니다. 박공사이의 틈을 가리기 위한 용도인데 모양이 지네처럼 생겼다고 해서 그렇게 부릅니다. ^^ 선생님의 비디오 클립을 세번정도 다시보며, 최대한 질문에 대답을 드리고자 노력했지만 충분했는지는 잘 모르겠습니다. 지금은 현대건축관련 일을 하고 있지만, 전통한옥목수를 12년 정도 했던 목수의 한 사람으로서, 제게 많은 가르침과 도움을 주셨던 선생님께 도움이 될까해서 이렇게 장문의 글을 남겨 봅니다. 건강하시고, 행복하시길 바라며, 앞으로도 좋은 비디오 클립을 많이 만들어 주시길 바랍니다. 고맙습니다.
Google translation: @mitramiru6450 2 days ago Hello, teacher. I am also a subscriber of yours, and I am grateful that I was able to learn a lot about Western wooden architecture from your video clips. I also liked the many useful tips related to woodworking. I am very happy that I have the opportunity to talk to you about our traditional Korean architecture. 1. Traditional Korean architecture sites start with cutting wood at a place called 'chimokjang' and making various materials needed for construction. Unlike in the past when the 'do-pyeon-su' who oversaw all the construction processes was the general supervisor of the site, the 'do-pyeon-su' currently oversees only the woodworking process of construction, that is, the structure and the window process. And traditional windows are made by woodworkers who traditionally specialized in making windows and furniture. The 'chimok' process is the process of cutting raw wood (originally Korean native pine, but these days, North American Douglas fir is mainly used) and carving, cutting, and trimming the space for the tenon according to the dimensions and various materials. The basic manufacturing method of Korean traditional architecture, windows, and furniture is the method of fitting. The basic method of fitting together the parts such as window frames, beams, main beams, dongjaju, jungbo, daegong, etc., which are connected to the pillars, by cutting male and female tenons in the designated places is the basic method of Korean traditional woodworking. The parts you saw were all parts that were processed by carpenters in advance at the 'chimokjang' factory and transported to the site. 2. The Korean traditional house, 'Hanok', is basically a floating house. It is very different from the Western method of installing pillars fixed to the ground, laying long lines fixed to the pillars, and supporting the load through the load-bearing wall. Hanok is a floating house where the foundation stone is placed on the compacted ground and the pillars are erected on top of the foundation stone, and it is basically a pillar structure that supports the load of the roof through the rafters, beams, and pillars. Also, since Hanok has a long eaves line, the pillars will not get wet and rot. Usually, you can think of it as having an eaves line that is more than 1m away from the wall. And, in Korea, the damage to wooden houses due to termites is minimal. Originally, all the parts of Hanok were not painted, but these days, they are sometimes painted with Oil Stain. However, due to the climate of Korea, pillars rarely rot. If the pillars rot, it means that the eaves line was not properly maintained. ^^ Originally, the roof of Hanok was a wet roof. The traditional method was to lay roof boards ('gaepan') on the rafters, place the remaining wood after the chimney, cover it with soil mixed with yellow soil and lime, and finish it with glazed and baked tiles. That's why the weight of the roof presses down on the house, and the pillars do not come off the foundation stone. However, these days, the trend is to move towards dry roofs due to issues with roof insulation, roof tile damage or roof construction defects, water leakage and rafter corrosion, and the cost of tile installation by tile technicians. 3. All Korean houses, including Hanok, are heated through a boiler system called 'Ondol'. 'Ondol' means that the floor is heated by heating the stones on the floor to warm the room. Since Hanok these days basically has an 800mm concrete foundation, the floor pipe work is done in advance when the foundation work is done. The site you saw now has only the basic structure of a Hanok, and the walls are made in advance using the paneling method. This is a modern method. Originally, walls of this type were made on site. The way the walls were finished can be said to be a modernization of the traditional method. The inner walls were finished with yellow clay mortar mixed with yellow clay and cement mortar, and the outer walls were plastered with a material mixed with yellow clay and lime cement mortar, and then finished with lime plaster. The insulation on the roof was rice husk charcoal made from burning rice bran. It is not a commonly used material, but you can think of it as one of the experimental eco-friendly insulation materials in Korea. 4. I think this video clip is a cross-section of the Korean construction market. I think it shows well how eco-friendly and passive housing, and prefabricated construction methods that have entered Korea as Western-style wooden houses have influenced the Korean single-family home market and traditional architecture. When you look at things like rice husk charcoal used as eco-friendly insulation, panelized walls, and 'mokguiyeon' that has been omitted and only the shape remains, I think the contrast between new and disappearing things is clearly revealed. Ah! The decorative ironwork that is attached to the joint of the gable is called 'jinecheol'. It is used to cover the gap between the gables, and it is called that because it looks like a gable. ^^ I watched the teacher's video clip three times and tried my best to answer the question, but I'm not sure if it was enough. I'm currently working in modern architecture, but as a carpenter who has been a traditional Korean house carpenter for about 12 years, I'm leaving this long message in the hopes that it will be helpful to the teacher who taught me and helped me a lot. I hope you stay healthy and happy, and I hope you continue to make great video clips in the future. Thank you.
I never thought i'd say this, but you, sir, have made the most enjoyable commentary video I've ever watched; Not much bias, digesting the way they do things, asking questions, thinking out loud, making connections. Nothing like a pure engineering mindset that transcends the boundaries of culture.
HTF does it not burst into flames if someone rubs their hands together too fast? JFC charcoal in the roof? It's beautiful and the craftsmanship is unreal but the flamibility factor...
@@michaelposey6529 😂 It’s not a charcoal briquette. This company is not JFC, but 유기산업 (Yugi Ind Co.). It’s an excellent flame retardant material and it follows South Korea’s construction safety standards.
I love construction based on mechanically interlocking. Rather than fastener dependent. Gravity holds the planet together. Sometimes limited movement is your friend. More of this content please.
It’s also much much stronger than stick construction. Timber frame really doesn’t cost that much more-30% maybe-but the structural gains are tremendous.
If it can bend it can resist forces that would break it. When we fasten things down to where they can't move, the energy from nature (hurricanes, tornados, earthquakes) has to go somewhere. If it's fastened down, it could break, but limited movement will allow the energy to bend the materials instead. Converting the energy to movement.
@@TheBockenator 30% more is a massive cost increase. Wtf are you talking about? Imagine if your landlord said a 30% rent increase doesn't cost much more.
Your willingness to look at crafts people from the world outside the US, to learn and appreciate different ways of doing things, makes you a great ambassador for your faith - and very refreshing. Thank you.
Terrific video! I've been all over Japan and as a once framing carpenter, and physics teacher, I poked my nose into every structure I could find. What I notice, might also apply here: Basic Chinese temple structure with some key elements missing (maybe). After I spent two months going all over Japan in 2016 I thought that diagonal bracing wasn't something often done in Japan. I was in Matsumoto a few days after the earthquake there. Saw a couple of collapsed structures. Old buildings, no diagonal bracing. (Windows right to the corner posts) They basically twisted and dropped. In Kyoto I saw a new office/retail building going up in between two existing buildings. No diagonals, but huge steel I beams. In the front where it might be all glass, sure. But on the blind sides? I think the huge steel beams and posts were basically bridge construction to add the rigidity. (I was then teaching at the RFK Ambassador schools in Los Angeles where the main building had huge diagonals. I would show my students out the window where the Hollywood Fault was and never worry.) In Japan I saw a few old barns and out buildings with the sides falling off, revealing no diagonal bracing. I thought I was learning something about Japan. My basic theory was this was Chinese Temple design taken a step too far. Last year we docked in Chosi , Chiba Prefecture, just up the coast from Tokyo. Walking around I again poked my nose everywhere I could get away with it... This time I saw diagonal bracing every where I looked. Newer structures. One thing that was different from American framing is the sole plate at the bottoms of the walls in garages. Very deep. Like 10 cm (4 inches) even though they rested on thick concrete footings raised above ground level. This was in garages where there was no sub floor structure. Civil engineering, bridges, highways, train stuff? To international standards, well built and no flaws that I could see. I'd have to say that as a general theory, my idea of no diagonal bracing isn't universal, but it does seem common. (I've never seen an American with a 16 ounce hammer put of any framed anything without at least tacking in a diagonal.) The basic idea in Chinese temple design is that the timbers are, like the house in the video, well connected so that if there is movement from an earthquake the building structure shifts with the forces but doesn't collapse. In Kobe, Japan many houses collapsed in the mid 1980s quake. The were built without heavy mortise and tenons, with a very heavy tile roof on top, the roofs moved differently from the walls and collapses. (American framed homes do well in part because most of our roofs are fairly light.) A long Shinkasen bridge to elevate the train collapsed in that quake because it was straight for too long, they quickly figured out to solve this problem. (I think some of these bridges they put a few twists, the trains all automatically stop if there's an earthquake.) If you do Chinese village mud wall construction, I've got lots of photos of buildings in partial collapse revealing how they were built/. People moved to the city, roofs weren't maintained, the walls melted in the rain. All in all to me it seemed like the Chinese even at the most basic level understood the building methods they used.
I had a home built in 🇯🇵 by a master carpenter and his son. Nails were purely decorative. Their joinery with only chisels was incredible to watch. No cost overruns or surprises. One of the greatest experiences in my life….
@@synckid - in my EU country, building contractors generally are very bad at cost calculations and often have conditions that facilitate cost overruns. So when they have a cost overrun, they charge more. Alternatively, fixed time and scope contracts often see quality issues, and fixed price contracts have duration and quality issues. An account manager of a large bank in the country told me about experiences with contractors as clients in the building industry. Not funny. They could not calculate the simplest projects but at the same time knew they could buy a very expensive car. And next be sent into the foreclosure department. In traditional building, based on a centuries old tradition, the masters precisely know what has to be done, the pitfalls in the work and site and materials needed and logistics thereof. Making a proposal that works well between client and contractor then is a piece of cake. In the research world of project management methodology the traditional way of building a house can be classified as a "paint by numbers" type project. It's clear what result has to be delivered and it's clear how it should be done. This takes both result and process uncertainty away. Been there, done that. Hit the ground running. The Gerries would say "senkrecht starten" (vertical take-off - that is, like a rocket). The man who came up with project risk classification (prof. Eddie Obeng), then distinguishes three other types: "making a movie" (result uncertainty - we know how it must be done), "the quest" (holy grail - we know when we have the result, just not how to get there), and "in the fog" (result uncertainty and process uncertainty). Many building projects start as a quest just because not enough planning went in, and then over time become "in the fog" when between contractor and client scope-changes happen. Such scope changes can be caused by a client changing their mind, but most likely happen when the contractor proposes a change because something turns out not to be available (either because it is not, or really because they assumed a much lower price or waited too long with ordering at a set price). In commercial building projects we see a large site with a contractor cabin in it and when you look into these cabins, you'll see full time planners working to make sure everything gets delivered in time, and if shift happens, they swap work packages in time to make sure the work continues. Contracts with vendors to the building-contractor have serious penalties.This also means the contractor will review the financial strength of their vendors, because any guarantee is worthless if using it means bankruptcy. As example of penalties, in my country, some governments when contracting a firm for roadworks, agree on a duration (calendar time) for the project that next is converted into a lease of the involved public infrastructure to the contractor, with the clause that the contractor can charge the government for the duration agreed in the first place. Such projects become a financial loss very quickly due to the expensive rent after the duration. And these projects never run over time. In other projects we see very long durations that may have been planned as a way to allow the contractor to use "cheaper" downtime to do the work, or as a way to teach citizens other, new to them, routes to commute.
@@garvinsimmons the something extra happens when you underbid on a job. When you are competing against half a dozen fly-by-night operations that all use dirt cheap Mexican labor, it's hard not to do.
I was not only impressed by the clever craftsmanship, but also the quiet synergy in which the crew worked. What a high level of economy of scale, organization, and efficiency displayed.
Having worked around the South Korean Rock Army! South Koreans are nothing short of impressive people! They work hard, smart, and make the most of the what they have. They’re amazing and we as Americans could learn a lot.
Over 50 years ago I was stationed in the Philippines. I have since stood in awe of the creativity and ingenuity. The Orient is far more fascinating than the west.
During my time at camp Humphrey’s I remember watching an about 60 year old man put a refrigerator on his back and walking down 6 flights of stairs because the elevator was turned off
Fascinating. Having studied Japanese carpentry, I expected the techniques shown would be similar, and this is because in ancient Japan, the best carpenters were said to be from Korea and many of their techniques were passed down after their tradesmen were invited over. Kongo Gumi for example, was the oldest company in the world, existing from 578 AD, and was started by Korean temple builders hired by Japan.
@@kenadrian27mix between china and korea but in modern time its looks very different, especially in entertainment culture, for huge example like idol culture its start in 1962 in japan and adapted by korean later on
@@kenadrian27 The structural technique shown is a version of 穿斗 carpentry, used in China since the Han dynasty, iirc, where the beam passes through the column and is locked in place by a cross beam, that also passes through the same column. What do you think Jingoist Chinese folks would think of Korean and Japanese architecture? It's mean and unnecessary to dismiss anyone's culture, like Japan did to Korea during WWII. Don't sink to that level.
just to add my two cents, from what I can see here in this footage, it's not entirely "traditional." no nail guns or even steel nails were used back in the days (even wooden peg nails were minimally used).
I did Italian plaster when I was younger. Those lads working on the walls DO have strong arms. Beautiful job. I need to show this to my old craftmaster, old man gonna love it. ♥️
Korean homes, especially the more traditional type ones such as this one, have built-in floor heating. It is fantastic during those cold, brutal winters. (Korea has four seasons to the max, spring and autumn is amazing, summers are humid and hot, winter are damn cold.) This home is beautiful and made with craftsmanship and pride.
@@jamesgeorge4874 There's more to do with climate than just latitude. Korea gets affected by high pressure systems from SIberia in the winter and the Pacific in the summer. I'm from NY and Korean weather definitely feels more extreme
@@jamesgeorge4874 To the north of the Korean Peninsula is Siberia, the coldest in the world. Initially, the United States did not have any supplies for cold weather during the Korean War, judging that Korea would be a savannah similar to West Africa, but as the Winter Front opened, many dead people occurred. South Korea's Gangwon State begins to snow from October to March, and North Korea's Kaema Plateu is where all the northern hemisphere's cold air currents gather due to westerly winds, so the temperature in the coldest month of the year is similar to that of Anchorage.
The structural engineering of traditional east Asian post-framed buildings is fundamentally different. They tie together the building with a box frame (made of heavy timbers with wood joinery) at the top half like a piece of furniture with legs, rather than using the ground for rigidity, make a whole assembly to spread load out on that box, put a heavy tile roof on top, and gravity plays a big part in keeping the thing together. This gives the whole building a little bit of flex in an earthquake where its center of mass can move relative to the ground without a lot of damage.
@@TrogdorBurnin8or strangely enough south eastern American cracker architecture is similar in many respects but because the floor is part of the structure above the pillars they don't need the heavy timbers for rigidity and weight. Unfortunately they face hurricanes so while the flexibility is extremely beneficial they ultimately rely on surrounding trees to avoid being blown off the pillars, but so long as they are surrounded by good trees they have survived countless hurricanes without using anything more than gravity to keep them on the pillars.
I've seen a doc of old Chinese buildings from thousands years ago without using a nail or screw. it was like a big Lego structure that can stand earthquake up to 9.0. Which it still stands today.
This explanation makes so much sense, while watching this video I was thinking, ok, the strength comes from all the joints coming together? Because the base seemed super unsecure, so it had to come from somewhere. Fascinating!
A natural stone plinth won't wick like concrete. My church in Virginia was built in 1840 and until recently it had original wood beams sitting on sandstone piers with no hold downs. Lasted 180 years that way - the original beams are still there, too. The only reason it changed is because we had so many people in there and got tired of the bounce house effect so we raised the whole thing to put more bracing & leveling in - but code wouldn't let us put it back down on sandstone blocks, so we had to build a CMU foundation and seal it before putting the church back down on it.
Depends on the stone, the temperature, humidity, and airflow I'd say, and if it's cracked of course. Water is a very tricky foe. If it's done right it is very possible. Usually wood underwater or in the dry tends to last, it's when air and water both have access you have issues.
@@joytotheworld9109 laws arent about the current condition most of the time, rather its about meeting a certain way of doing it, if using a stone isnt included or premitted to be used, then it will fail to meet the requirement regardless of the condition of the rock. like condition is only applicable to methods that are permitted.
The stone under the pillar is a foundation stone made of granite. The pillars do not come off the foundation stone because the heavy tiles and the heavy wooden structure press down with the weight of the entire house. The characteristic of traditional Korean houses is that the eaves are long, and because of these long eaves, the wooden pillars exposed to the outside dry well due to the light and are well ventilated, preventing them from rotting. On the contrary, the pillars inside the closed structure often rot. The exterior finish is made of yellow clay, sand, and lime. In the past, the pillars were trimmed and the remaining wood, yellow clay, and lime were sprinkled before the tiles were placed. but in modern times, ceiling insulation is done using rice husk charcoal. Since traditional Korean houses use floor heating, they use thick, eco-friendly insulation materials even if the insulation level is a little low.
In addition, HVAC inside the building is performed by natural ventilation. Communication and electric lines penetrate the walls and go up to the ceiling, and are distributed above the ceiling. The bathroom water line is finished by going up inside the separately installed masonry wall, and then the waterproofing process is performed. There seems to be no explanation for the sewage line, as it is a procedure that has already been performed in the foundation work and is already a widely used method.
As I wrote in another comment, this is very similar to the traditional Japanese way of building. I know that Korea and Japan have a complicated and controversial history of relations. But despite this, they are still close Asian cultures that have adopted many things from each other.
It's silly, but every time I see you confronted with knowledge that you're not familiar with, YOU ADMIT IT and say, "Hey, there's something I can learn." It makes your content so approachable to beginners, like I was, when i first watched your circular saw basics video years ago. I'm astounded that I can be proud to watch and learn from the content you create, even after all these years. P.s. I've rehabilitated a 100 year old school house into my home since I watched that first video, and Essential Craftsman always seems to be my first search when confronting a new challenge.
It's a rare thing to come across these days, and I've always seen admitting what you don't know as a true sign of intelligence. The smartest people I've known will be the first to say they're not certain what they're looking at and then they take the time to learn.
Scott, I liked your voice over. It was like I was sitting here with my brother watching this. These men are truly artists. The quality of the work and design is just awsome, I thought the black stuff in the roof was shredded tires, but I stand corrected after reading the comments. I am digging a bunch of that red clay out from my crawl space. That stuff gets so hard you could build a house without the framing. I have always said if we spent the money spent on wars on doing good things the whole world could have things like this. You started as a TH-cam creator passing on skills, ( as many others) and have become a friend to so many of us. Please do more of these, I really enjoyed it.
Charcoal rice husks - insulating but also resistant to infestation - the wall panels matts have this as well, whole house is breathable because the natural construction materials
IIRC Similar material is often used in some Japanese construction, particularly crawlspaces that don't need access. Charcoal is added for insect resistance as well as humidity, odor, and insulation as the charcoal is very porous. Not exactly activated charcoal but in the sheer volume they use, it does similarl things. Great video. Definitely demonstrates more broadly a certain economy of construction which lets each trade really focus on their particular skill set. I think also worth noting that in many parts of east Asia homes aren't so much valued compared to the land they sit on. I dont think most traditional construction methods sit around for more than 50 years without serious preservation like in the case of Temples. Just observations over the years, open to being corrected if I'm wrong.
Sir, I have never watched a video of a house put together BUT seeing how excited you were getting and your joy on reviewing the video genuinely put a smile on my face
18:00 Many if not all these Korean homes are heated by radiant heating from floor. In the old days it would've been the fire/heat stoked from the kitchen directly but "new" ones like this will be heated by hot water pipes buried in those (concrete) floors.
Also, broader context, almost no one in the world does residential HVAC the way they do in the US. Traditionally in Europe it's all radiator systems for heat (hot water, shared with the plumbing, circulated through physical radiators mounted to the floor in each room) and no cooling, while in Asia, they skipped right from traditional fuel burning to individual heating + cooling mini split units in each room. The fancy version of that is just combined outdoor units that drive 4-6 indoor units a piece, with super efficient heat pumps and variable speed motors. And all you need to run indoors is a slim little flexible pipe to carry coolant. Almost no one in the world bothers with all the ducting that the US does, and they all get temp per room controls!
Yep, I learned back in architecture history class during school that the Koreans had this stone based radiant floor heating system as far back as the Neolithic era or something. Kinda cool.
@@jyc313 Technically, only Northern Koreans had heated floors; Southern Koreans did not, as the climate was warm enough. It was not until the Little Ice Age of the 13th century that heated floors spreads to Central Korea. And not until the Little Ice Age of 17th century that heated floors spreads to Southern Korea. However, some rich landowners and the middle class used heated floors even before the Little Ice Age, and Koreans have definitely known about them since the 4th century BCE. FYI, Northern Korea means North Korea minus its capital region. Central Korea means the South Korean capital and the North Korean capital, plus one more province to the east. Southern Korea means the rest of Korea.
@@Isl33p True but, yes and no. There were evidence of homes in the southern parts of the peninsula that had “ondol” flooring, or something similar to it before ondol as we know it today. We just have to safely assume it may not have been used as often as their counterparts that lived more north. The entire peninsula in the winter gets really cold, even in the southern tips. So you’re not wrong, but also not 100% correct. The classes we took included seminars that focused on East Asian Architecture and guest lecturers on subjects taught the series.
Yes, between the Korean, Japanese, and Chinese, you have a LOT to learn. Remember there a lot of nail free buildings over 700-900 years old over there. Those panels in the walls are like our early wattle buildings - they use interwoven bamboo, paper and wood to create the wattle to provide insulation and hold the plaster. Those beams are interlocked by using mortise and tenon and wood pins. Yes, its a lot like our adobe but with more lime and clay. What you see are the typical pre-fab style homes there. Those beams etc. are cut and fitted in a warehouse style shop from an original design. What you saw was a custom pre-fab home.
I didn't know I would enjoy someone's commentary over a construction build. This was great. It was nice to hear your point of view as an expert. Made construction video much more enjoyable!
Very cool to see these old techniques still in practice! No rebar fixes in the foundation, and no steel brackets on the frame. Just make physics your plaything
There's a wonderful Korean House in Highland County Virginia It was disassembled and shipped from South Korea to 4,000 ft on a Mountain top in Virginia ❤
The crew who did the form and pour of the foundation and floor gets an award. All of the amazing joints are not valuable without perfection to begin with
Hi Scott, I have been watching your videos for years and always found them captivating, even more so since becoming a homeowner, but I've rarely been glued to content on youtube like I have been glued to this one. Watching a master craftsperson watching something unfamiliar and analyzing it is extremely rewarding, even if virtually none of this will ever be part of my own skillset. I have always been impressed by the open and sharp mind you have retained over a long life of work, but never more so than with this video. Thank you for doing this. I hope you can find more detailed clips of skilled work from different contexts like this to comment on. All the best to you and your family for the new year.
i am always envious of how our Asian brothers and sisters treat everything that they do like an art. I hope they never lose that part of their culture.
Don't be mistaken. They do have cold bleak concrete buildings too. Single family homes, especially in the countryside are a treasure and they are meant to look like one.
@@alis49281 oh i know that but you dont see these types of things in the West at all - like the old way of making chalk, ink, blades, etc. Lots of lost professions that we in the West just wont invest in for whatever reason.
@@The_Zilli A lot of it has to do with resources rather than art. Lack of metal is one of the major reasons why Japanese and Korean houses are made through joinery. Iron was an expensive commodity. China is the only Asian country that didn't use nails or iron due to complacency and stagnation. Rammed earth blocks were still the most common method of home building by the end of WWII.
@@brainplay8060 I understand resources are different in many of these Asian countries however that wasnt what i was referring to. As others have posted in the comments, this is not a common construction method however Ive found that only in Asian countries you will find things being produced the traditional way, be it ink, chalk, building, fishing, what not, Asian cultures take everything to the next level it seems. Like look at how the Japanese are with their fish market, etc. That's all, it's very unique and I hope it's something the Asian cultures never get rid of as technology develops.
@The_Zilli @The_Zilli it is one thing to improve methods, another to distort them that they fail their function. Wood frame houses are still built here in Europe, still the same materials, but machines helped and improved it all. (No, US American wood frame is an abomination of what wood frame is supposed to be) Sure, hand made clay shingles are nice, but what machines make is just as good. The problem with buildings lies mostly in the materials: not reusable, not even recyclable, some even toxic or cancerous. Currently we are in a revolution where old materials are exploited to their maximum and suddenly we have incredible properties unmatched by concrete. The Korean house in the Video uses technology for prefabricated elements made with old materials. Where Europe uses willow or hazel, they have bamboo. They even use bamboo where we use reed. The clay and lime plaster looks very familiar though!
About the wood post to concrete issue. Let's go to zig-zag style fence building and moisture. If you put a rock on the ground to hold up a fence post, the moisture will creep up and around that rock and into the post bottom. By stacking another rock on the first you have created a break. The moisture will not creep up the second rock. You can stack two flat ones on the lawn and see for yourself in the morning dew. In the foundation, that support block is loose, making a break. Also they can move around the seating to square up the upper frame. Perhaps the Koreans are thinking along that line. I've been doubling up the sill protection on some smaller jobs (garage, shed, gazebo, garden structure) by adding a layer of asphalt shingle (grit side down) to the strip seal, or two layers of shingle. What really helps is two layers of shingle in the pocket when using concrete "deck-blocks." I've been able to keep my eye on some sitting low to the ground, for over 15 yrs. I think it helps dry things up much faster after rain. Works great.
@@mousbleu I would agree, tract housing builders don't necessarily have a good quality build. But there are quality builders out there, we just need more of them.
This is all clay mortar. The outside finish could be coloured lime mortar or mortar made of white clay and white sand. The wall strukture is built without any moisture barrier and is able to carry moisture out and in. For those types of walls it is necessary to use only natural materials like clay, lime, straw, wood, etc. No modern coatings which could add a blocking layer into the wall system. The white textile on the roof system is just the packaging for the insulation. The one on top of the osb is a wind barrier (one could use OSB alone as well, if you tape and glue it). I built my house pretty similar to this and worked as a clay contractor for a few years here in southern germany.
I love the organization and cleanliness of the jobsite! I was impressed with how fit and healthy the workers looked. Being a plumbing contractor of 30 years I would have loved to see the phases of the plumbing, types of material and techniques. I have done a bit of plumbing in Europe on our properties there and find the differences interesting. Thank You for the look into Korean building, fascinating.
Natural clay plaster and lime plasters breathe and create a much healthier living experience. No off gassing and no moisture issues. These houses feel so much better for quality of life too. Thanks for sharing!
That's right The printing wood blocks of the Tripitaka Koreana and the microscopic Buddhist script, created in 1236, are still intact and preserved thanks to this technology
ya as you can see from the comment below in korean if you translate it to english the block under those posts is not concrete, it's cut granite, which doesnt transmit moisture like concrete does. so the granite is the moisture barrier, and a lot more durable of a moisture barrier than anything we'd use in the west. i also think the thing you said cant be dirt is exactly dirt with a high iron content. otherwise i share all your observations and questions. there is a lot to be appreciated in the way this thing is planned and executed and a number of things we'd wanna know before we tried to do anythng like that on our side of the world. suspect if we'd seen the foundation and bottom slab from beginning to end we'd have some answers
Thanks for this video. I like how the lumber comes pre-cut and made to fit like a glove. Its like putting together Ikea furniture on a grand scale. I am also impressed by the simple drawings, clean work & the neat housekeeping.
This is ridiculous. Hanok houses as we know them today date back to the late 15th century , they did not exist in that style before that and looked more traditional Chinese style.! That Hanok style was 100% taught to Koreans by Japanese during the Japanese invasion and occupation of Korea since 1595. There were no Hanok in this style in Korea before that. This is not Korean architecture, this is 100% traditional Japanese architecture !
@@Official-OpenAI This is actually really amusing that people seem to know so little about history at the time of the internet ! Thanks for the comment, i appreciate it. I have nothing against Korea, i just fin d it hilarious that Koreans would consider the Hanok style to be actually traditional Korean architecture. It would be like saying that the Alhambra in Spain is actually Spanish architecture, it is not, it is Moor architecture. Koreans have a tendency to do what the Spanish do here in Europe, they assume. The Spanish completely forget that they were arabic for much longer than they have been spanish and that spain was under Arabic administration for 700 years. 90% of what we con sider spanish today from Flamenco to Tapas to Paella to the Alhambra to the spanish language itself comes from arabic influence. Most of British and Irish and Scandinavian culture is not western or christian, it is Celt and Druidic. Korea's culture is mostly Chinese just like Japanese culture. Except Japanese have no problem acknowledging how China influenced Japan, but Koreans really have this injured pride thing which makes them act like they built the Egyptian pyramids. That's more funny and ridiculous than it is annoying.
@@chappy3125 You mean my 약 ? Because you see the funny thing is that Korean medicine as well comes from Chinese and Japanese medicine. Isn't that funny ! Just a quick search will confirm it to you ! Make no mistake, i know Korea very well.
In Iraq . The wires are run through the house . Then plastered over with raw gypsum paste . Outside walls are rock plastered over with mortar then painted white .
Scott said it correctly- sustainable but not energy efficient, living in an old Japanese farm house I can affirm that there are gaps between the timber frame and plastered walls, it is drafty hehe The relief cuts in the ceiling boards are to prevent cupping. Great video! would love to see more of that style ❤
The homes being preserved in the UK that have a similar construction they use a rope made out of wool and dip it in animal grease as a seal between post and panel before putting the earthen stucco to prevent drafts, just like they did back in the day.
Yeah, Japanese didn’t bother with the underfloor heating the Korean’s invented. Korean’s don’t really understand that😂 Korean farm houses are a lot warmer
@@clareryan3843 Yes...The Japanese culture has developed and normative belief in a principle of localized or "self heat" often using something like a 炬燵 "kotatsu." A very different mindset and approach to living that many cultures in the world...
This was such a treat. Thank you for enriching us. Liked, subscribed, and making the rare comment in hopes that the algorithm brings me more content like this. Happy New Year to everyone!
To see a Japanese carpenter build a home I highly recommend Shoyan Japanese Carpenter, I believe he is on his 5th house building series for TH-cam. He dubs all of his videos in English and mostly build timber framed homes built to modern air tightness standards.
Just found this channel and absolutely loved it. Can we get more reactions to overseas construction videos/techniques? It is pretty fun to see someone who has been doing similar work, reacting to the same type of work from across the pond. Asian construction especially because those cultures have some of the oldest buildings on the planet, and they still exist for a reason. In some extreme cases, some have been through typhoons, heatwaves, extreme cold and severe earthquakes for hundreds to thousands of years. Thanks for the enjoyable video.
As a former residential contractor. I've seen Korean residential construction videos before and I am fascinated and enthralled by the building systems and beauty. This was a relatively simple build compared to the curved structures I'm seen built before. I'm a big proponent of simple roof lines and low pitches which, as evidenced by this video can be as beautiful or even more so with the last lasting roof tiles, The US is in sore need of a rethink of our construction techniques. I say all this as someone who is disgusted by the garbage, garage front facade boxes being foisted on US homebuyers.
If Mr. Wadsworth is up to, I think it would be fun to hear his opinion/observations on Shoyan or The Carpentry Life, they are channels focused on japanese style carpentry. And I completely agree, I started watching this channel because of the differences on how we build houses where I live compared to the US, and so far I have learned more than I could have imagined. Merry Christmas!!
I know nothing about building, other than having been a home owner and had to fix, repair or replace just about EVERYTHING! I loved the aesthetic of the building. Your questions were the same that occurred to me. This was fun to watch, thk you!!😂❤ Grandma in Texas
Great commentary. Thank you for reposting this video so that we can all learn from each other across many cultures. Please do more of these from all around the world. There is so much to learn for each of us.
Great video. I hope you can do more of these EC! It's actually educational and helps broaden our worldview here which, lets be honest, can be a bit myopic at times in the USA:);).
Thanks so much for this revealing look at Asian construction. I've enjoyed several of your videos, but this one is the best yet. In the 90's I worked for Roland Schweitzer, an architect in Paris. As a Parisian, Roland Schweitzer came to his love of wood architecture through his love of Japanese architecture, and he hired me in - in part - because I was a Californian familiar with wood construction. I subsequently learned how different the ancient Japanese and modern California methods were. Whether you see it as a good thing or not, the truth is the US is - by global standards - somewhat obsessed with using industrial developments to improve safety. I'm proud of many of our US developments and the US instinct to tinker, improvise and improve things. Still, it also disturbs me that there is often a loss of craft in our industrial approach to buildings. Also, industrial improvements are sometimes implemented for a speculative, gimmicky entrepreneur to make a buck in concert with a code upgrade. The reality is that this lack of craftsmanship and the presence of this entrepreneurial speculation have some safety ramifications, too. Whatever the case, Roland Schweitzer made sure I understood that many shake table tests have been performed in Asia with posts and lintel construction. What they discovered - certainly not intended to be an exhaustive condemnation of shear walls - is that placing a shear wall between the lintel greatly increased the likelihood the lintel would fall and the structure would collapse. The lesson I was to draw from this experiment was that some flexibility in a structure is valuable in an earthquake. Our US method of construction is not built around this model. We build rigid structures designed to absorb the relatively unmitigated force of the building's sideways force. The approaches (post and lintel versus shear wall) are very different. While flexible buildings have merits, they are also tough to analyze and have fallen out of modern deterministic favor.
I remember watching the video's for how this house was constructed and I absolutely loved every moment of it. No nail guns in sight for main framing, everything fits together. Wouldn't it be nice if New Zealand builders had the skills to build this way..
Where has this channel been. I’m glad TH-cam finally got it together and recommended you. Your passion for your craft is tangible and your input is so thoughtful and adds to the content you are watching. Nice stuff 👍🏻
I admire how you embrace the artistry of people from around the world, appreciating their unique techniques. It’s a testament to your faith and a breath of fresh air.
I have my gripes about the build as well, but one thing I really admire was the attention to detail everyone had here. I feel like my jobsites are filled with people and subs who just don't care. I've seen roofers blow nails out through the patio and don't bother to fix it, hvac beat the heck out of boots to where you have air leakage issues, and many others. Even the lumber looked so much better and so much less waste than what I buy. I would feel so relieved to have a crew like them building my client's homes.
Western construction methods give so much structural strength that you can get away with using mediocre wood. Joinery cannot say the same. The box frame design requires high quality wood cut to very exact measurements or risk serious failure. The lack of quality control that we see with a lot of developers is due to poor management who aren't actually supervising and reviewing the work. Easier and less costly to hide it than replace and redo something.
Much construction in America is very degraded by greed. Pathetic people hired for cheap wages and unsupervised. No pride. No integrity. Then there are also high quality builders. Probably the same all over the world.
@@jimmock1155 With tract homes and national builders I tend to agree, because their focus is on fast and "cheap." As a gc who builds custom and semi-custom homes and is there working with basically every crew everyday I'm still noticing quality has dropped dramatically. The subs I used, know and respected over the years eventually hire newer workers. The older guys I trust retire or go on to be supers, and newer guys take their place. Unfortunately, as a early 30's millennial myself, I'm disgusted by my generations work ethic. While many just need more training and work experience, most do not ask for help and will bash their way to the end of the day, get paid and dip. My job has become a babysitter and it feels demeaning because I want to be their to assist and build a home my clients love and now I've turned into a full time inspector/judge. I hope it changes, I really do, because even the subs throw their hands up at this new work ethic and are still ending up calling in the old guys to fix the mistakes.
This could be a video series a really successful one of going the different countries learning how they do first hand from them with the Foreman telling you how it's done.
13:44 Gravity does not hold the field together. The edge and ridgeline are fastened and the interlocked field creates unified mechanical strength. Like binding a layer of boxes on a pallete with a ratchet strap will let you pick up the whole layer and while the boxes in the center of the layer hold their place by shearing friction, except this is even stronger because of the interlocking of the field.
@ryandekalands3842 Nope. As long as the outer edges stay bound the inner field will stay interlocked. And if the roof gets flipped upside down you got a whole lot of bigger fish to fry xD
While not designed to resist earthquakes, hanok’s lightweight and flexible construction can actually help absorb seismic shocks, reducing the risk of damage. Thats the reason they dont tie structure to the foundation
@@SingleStackedfrom what I saw their typhoons are MUCH more gentle than hurricanes... But they are in mountains so flooding and landslides are the problem not the wind.
I am an expat living in the countryside here in South Korea and the level of craftsmenship and materials is far superior to some the stuff the US uses. I have a half hanok style house similar to the house in this video. It will last centuries compared to a North American home.
Señor he visto muchos de sus videos y me agrada el hecho de ver que una persona como usted a pesar de su experiencia puede ver fuera de la caja y seguir aprendiendo cosas nuevas y de otros lugares por supuesto. Este video ya lo había visto yo anteriormente y si ciertamente me causó curiosidad verlo en sus videos. Sinceramente un aprendiz más aquí mirando sus videos les agradezco por su humildad para enseñar sus conocimientos
wow Im Korean, but never seen anything like this.. I visited my dad last year and he has told me so many Korean traditional house contructions because he's retired urban planner and he's fire egg (Best Friend) is a constructor in Korea does a lot of these kind of house builds. He would really enjoy this video, and I think I'm going to show this one to him and see if he can tell me any of it! Looked amazing!
First time on this channel, Very captivating Introduction. I think I have entered a stage in my life where houses and yard trimming seems very satisfying and something to look forward to. Cheers and Much Love
Whoa. I am, at once, amazed and also not surprised at all to see this type of craftsmanship being used on this part of the world. I built a kitchen island for a client once using basically the same technique. Totally out of my comfort zone, but the client was on board and I just picked away at sorting out where to put what kind of joinery. Castle joints on top where the aprons all tied together, draw bore tenons holding the stretchers together, and dovetails holding the interior stretchers together. They did this exact thing, except bigger, and better, and proooobably quicker too😬
I actually looked up how to call Hwang-Toh (황토) in English. It's Ochre. It's the yellow dirt-like material that was applied to the wall. You were curious, and I was, too :)
Good morning merry Christmas, you would be surprised how construccion takes place in other countries, for instance Mexico 🇲🇽, I know a little about construccion and you would have a heart attack about how a lot of houses are built here where I live, specially because regulations are not followed, I wish I had enough money so I could hire you to come down here and help me build a house, God bless you and your family. Saludos
El canal de CotaParedes y el de Appaloosa Arquitectura son muy buenos canales mexicanos para aprender algo de arquitectura y mano de obra. Saludos desde Texas
@@THE_BaconPirateyes it prevents insects as they do not like pure carbon. And yes, if a fire source were to start it would generally not propagate unless there was another fuel source. The material is not dense enough and doesn’t have enough unburied material on the outside to hold a flame unless superheated. And I believe it’s essentially the same material sandwiched inside the wall segments.
@@218philip - Organic leather! Clearly better. Like "Corinthian Leather" in the old Chryslers when Ricardo Montalban was pushing them (it was a 100% fabricated marketing thing!).
Clay like it was used on half timbered houses here in europe. It gains popularity as it is a breathing material for unique room climate because its not a moisture barrier.
I find your presence very comforting. I am a building enthusiast, never got a chance to go to school for architecture. This is very nice content. Thank you!
Fan of your channel. Appreciate the new perspective. Would be great to see you get out a bit more. There’s a whole ‘nother world out there beyond 2x4, plywood, and drywall when it comes to house construction.
It's timber framing.. It's not too common, but timber framing is done in the US.. I'm quite sure the typical Scandinavian methods are similar to what's done in the US. In fact, I'm sure there's inspiration from there in the US.
The weather on the Korean Peninsula is harsh. Its annual temperature range ranks within the top 5 globally. The difference between seasons is extreme - summers are hot and humid while winters are cold and dry. Even people from Africa say it's hotter than their homeland when they come to Korea, while Russians say it's colder than their homeland. Moreover, there is a monsoon season that doesn't exist in Western countries. Korea's summer monsoon rainfall is ten times higher than Europe which evenly distributed precipitation pattern throughout the year. Understanding these climatic characteristics helps us to better understand traditional Korean building techniques. Traditional Korean wooden buildings (Hanok) originally did not use nails at all. Instead, they used joining techniques to fit wood pilllars together like 2:28 which allowed the wood to expand and contract naturally with the wild changes in humidity. There are said to have been around 80 different types of these techniques. 12:55 The traditional roof was originally structured with alternating male (convex) and female (concave) tiles, and their placement were carefully designed to withstand the massive rainfall during the summer monsoon season while ensuring proper drainage, and the angle of the eaves was carefully adjusted to ensure proper drying of the woods in the sunlight. The ondol (floor heating system), which wasn't shown in the video, was also a product of adaptation to these environmental conditions. While times have changed, Western construction methods have been adopted, and materials have evolved, the climate remains unchanged. Korea's environment, which requires adaptation not just to one distinctive season but to two extremely different seasons, became a major reason for developing construction methods different from those in the West.
So those bags of back material that they put on the roof were rice hulls/husks that have been turned to charcoal..... and the wall panels are also rice hulls/husks, (but not as charcoal LOL) I THINK .... we didn't really get to see it close up, but I've seen them being made, and they wrap them in a thin sheet and it's all sewn together... and there are piece of bamboo sort of woven together around that, and then the mod layer is put on that... the bamboo is used to help hold the mud on.... I saw how they do in Japan and have been under the impression it's essentially the same in South Korea, but I'm not expert on Asian House Mud lol 0 I really fins it all just so fascinating.... but you will should look into the South Korean tradition home heating systems... it really is ingenious and incredible!
Hello from South Korea:) very traditional and not a typical house in Korea these days. yet I'm happy that the traditional technique is still in practice and you enjoyed it😊 that roof insulation was rice husk charcoal. I'm learning something new, too! Walls were constructed with clay or clay/durt mixture. No concrete stuff at all except for the white top surface, I think (it was limewash). You can pressure wash and the walls can be taken down😅 but that's the traditional way. I believe the house is not fasten to the ground. Gravity only, and moisture prevention method is the square piece of rock isolating wood from the ground moisuture, traditionally. I'm pretty sure that floor of this house is heated via water pipe installed in the concrete slab, making it kinda moisuture proof during the cold season? Real traditional houses were constructed with a system that circulated hot exhaust from fireplace under the floor usually built in the kitchen as cook/heat dual purpose or separately for the purpose of heating the house. Floors were constructed with clay and rock slabs called "ohn-dohll" (sorry for miss spelling, ondol is the right term) which literally means "heat stone" which help regulate and sustain heat for a long period of time once heated. Those are replaced with water boiler system these days. I'm not a construction worker, so not sure what wood or treating technique was used. This is some of the answers I can give you! Long time subscriber of ur channel and love the stuff you and your son present to the world. Watching the construction with your reaction at the same time was a dang good end-of-year present. Thank you and happy new year🎉
Nice info thanks
The white coating looked like limewash, which makes me wonder how well it would perform over the brown plaster, as when lime plaster dries, it's much harder than the mud-based plaster.
@@AkbarZeb-p6f yes the other Korean dude explained that it is limewash! learned something new:) idk about the performance..
The only thing that bothers me about using gravity-only to hold the posts on the foundation is that they're right up against the edge. If any shifting does occur... one side or the other has nowhere to safely shuffle to. I know people wouldn't like how it looks, but I would seriously want a few cm of extra foundation to allow it to adjust over time without collapsing.
rice husk charcoal has a use outside fireworks? Huh...I guess that makes sense. Dunno about the fire safety.
Enjoying an American commentary on a Korean construction from Europe is the glory the internet was meant for!
Peak globalization

i dig that xD greetings from switzerland
선생님. 안녕하십니까? 저도 선생님의 구독자로서, 선생님의 여러 비디오 클립들에서 서구목조건축에 관해 많은 것들을 배울 수 있어서 감사했습니다. 또한 목공과 관련한 여러가지 유용한 팁들도 좋았습니다. 그런 제가 선생님께 우리 한국 전통건축에 대해 말씀드릴 기회가 생겨서 아주 많이 기쁩니다.
1. 한국의 전통건축현장은 '치목장'이라는 곳에서 나무를 재단하고, 건축에 필요한 각종 부재를 만드는 과정으로 시작합니다.
모든 건축과정을 총괄하던 '도편수'가 현장의 총감독이었던 예전과는 달리, 현재 '도편수'는 건축의 목공과정 즉 구조물과 창호까지의 과정만을 총괄해서 감독합니다. 그리고, 창호는 전통적으로 창호와 가구를 전문으로 만들던 소목장들이 전통창호를 만듭니다.
'치목'이라는 과정은 원목(원래는 한국 자생종인 육송이나 요즘은 북미산 더글라스 퍼를 주로 사용합니다.)을 재단하여 치수와 각종 부재에 맞게 장부의 자리를 파고 깍고 다듬는 과정입니다. 한국 전통 건축과 창호, 가구의 제조방식의 기본은 짜맞춤방식입니다.
기둥과 연결되는 창방, 도리, 대들보, 동자주, 중보, 대공 등등의 부재를 정해진 자리에 암,수의 장부를 파서 짜맞추는 방식이 한국전통목공의 기본입니다.
선생님께서 보신 부재들은 전부 '치목장'인 공장에서 미리 목수들에 의해 가공된 상태로 현장에 운송된 부재들입니다.
2. 한국전통가옥인 '한옥'은 기본적으로 떠있는 집입니다. 지면에 고정시키는 기둥을 박고, 기둥에 고정된 장선을 깔아서 내력벽체를 통해 하중을 받치는 서양의 방식과는 많이 다릅니다. 한옥은 다진 땅 위에 주춧돌을 놓고 주춧돌 위에 기둥을 세우는 떠있는 집이며, 기본적으로 지붕의 하중을 서까래와 보 그리고 기둥을 통해 받치는 기둥구조입니다. 그리고, 한옥은 긴 처마선을 가지기 때문에 기둥이 비에 젖어 썩을 일이 없습니다. 보통 벽면에서 1m 이상 떨어진 처마선을 가진다고 생각하시면 됩니다. 그리고, 한국은 흰개미로 인한 목조주택의 피해는 미미한 편입니다.
한옥의 모든 부재는 원래 칠을 하지 않습니다만, 요즘은 Oil Stain을 칠하기도 합니다. 하지만, 한국의 기후 때문에 기둥이 썩는 일은 거의 없습니다. 기둥이 썩었다는 것은 도편수가 처마선을 제대로 잡지 못했다는 뜻이기 때문입니다. ^^
원래 한옥의 지붕은 습식지붕입니다. 서까래 위에 지붕판('개판')을 깔고, 치목을 하고 남은 나무의 잔재를 올리고 그 위에 황토와 석회를 섞은 흙을 덮고, 유약을 발라 구운 기와로 마감을 하는 방식이 전통적인 방식입니다. 그래서 지붕무게가 집을 누르고, 기둥이 주춧돌을 벗어나지 않습니다.
하지만, 요즘은 지붕의 단열문제, 기와의 파손이나 지붕 시공시 결함으로 인한 누수와 서까래 부식문제, 기와기술자의 기와시공의 비용문제 등등으로 인해 건식지붕을 많이 하는 추세로 넘어가고 있는 중 입니다.
3. 한옥을 포함한 한국의 모든 주택은 '온돌'이라는 보일러시스템을 통해 난방을 합니다. '온돌'이란 바닥의 돌을 데워 방바닥을 따뜻하게 해서 방을 데운다는 뜻입니다.
요즘의 한옥은 기본적으로 800mm 콘크리트 기초를 하기 때문에, 기초 공사를 할 때 바닥배관 공사를 미리 해둡니다.
지금 보신 현장은 기본적인 구조만 한옥의 형식을 따고 있고, 벽체는 패널라이징 방식으로 미리 만들어 온 벽체를 시공하는 방식입니다. 이건 현대적인 방식이죠. 원래는 저런 형식의 벽체를 현장에서 만듭니다. 벽체를 마감한 방식은 전통방식의 현대화라고 말씀드릴 수 있겠습니다. 황토와 시멘트 몰탈을 섞은 황토몰탈로 내벽을 마감하고, 외벽은 황토와 석회 시멘트 몰탈을 섞은 재료로 미장을 하고, 소석회 미장으로 마감을 했습니다.
지붕의 단열재는 쌀겨를 태운 왕겨숯이었습니다. 자주 쓰이는 재료는 아니고, 한국에서 친환경 단열재로 나온 실험작 중 하나라고 보시면 됩니다.
4. 저는 이 비디오 클립이 한국의 건축시장의 단면을 보여준 비디오 클립이라고 생각합니다. 친환경과 패시브 주택 그리고, 서구식 목조주택이 보급되면서 한국에 들어온 prefab공법등이 한국의 단독주택시장과 전통건축에 어떤 영향을 미치고 있는지를 잘 보여주고 있다고 생각합니다. 친환경 단열재로 쓰인 왕겨숯이나, 패널라이징된 벽체들, 생략되어 모양만 남은 '목귀연' 같은 것들을 보면 새로운 것과 없어지고 있는 것들의 대비가 선명하게 드러난다고 생각합니다.

Hello, teacher. I am also a subscriber of yours, and I am grateful that I was able to learn a lot about Western wooden architecture from your video clips. I also liked the many useful tips related to woodworking. I am very happy that I have the opportunity to talk to you about our traditional Korean architecture.
1. Traditional Korean architecture sites start with cutting wood at a place called 'chimokjang' and making various materials needed for construction.
Unlike in the past when the 'do-pyeon-su' who oversaw all the construction processes was the general supervisor of the site, the 'do-pyeon-su' currently oversees only the woodworking process of construction, that is, the structure and the window process. And traditional windows are made by woodworkers who traditionally specialized in making windows and furniture.
The 'chimok' process is the process of cutting raw wood (originally Korean native pine, but these days, North American Douglas fir is mainly used) and carving, cutting, and trimming the space for the tenon according to the dimensions and various materials. The basic manufacturing method of Korean traditional architecture, windows, and furniture is the method of fitting.
The basic method of fitting together the parts such as window frames, beams, main beams, dongjaju, jungbo, daegong, etc., which are connected to the pillars, by cutting male and female tenons in the designated places is the basic method of Korean traditional woodworking.
The parts you saw were all parts that were processed by carpenters in advance at the 'chimokjang' factory and transported to the site.
2. The Korean traditional house, 'Hanok', is basically a floating house. It is very different from the Western method of installing pillars fixed to the ground, laying long lines fixed to the pillars, and supporting the load through the load-bearing wall. Hanok is a floating house where the foundation stone is placed on the compacted ground and the pillars are erected on top of the foundation stone, and it is basically a pillar structure that supports the load of the roof through the rafters, beams, and pillars. Also, since Hanok has a long eaves line, the pillars will not get wet and rot. Usually, you can think of it as having an eaves line that is more than 1m away from the wall. And, in Korea, the damage to wooden houses due to termites is minimal.
Originally, all the parts of Hanok were not painted, but these days, they are sometimes painted with Oil Stain. However, due to the climate of Korea, pillars rarely rot. If the pillars rot, it means that the eaves line was not properly maintained. ^^
Originally, the roof of Hanok was a wet roof. The traditional method was to lay roof boards ('gaepan') on the rafters, place the remaining wood after the chimney, cover it with soil mixed with yellow soil and lime, and finish it with glazed and baked tiles. That's why the weight of the roof presses down on the house, and the pillars do not come off the foundation stone.
However, these days, the trend is to move towards dry roofs due to issues with roof insulation, roof tile damage or roof construction defects, water leakage and rafter corrosion, and the cost of tile installation by tile technicians.
3. All Korean houses, including Hanok, are heated through a boiler system called 'Ondol'. 'Ondol' means that the floor is heated by heating the stones on the floor to warm the room.
Since Hanok these days basically has an 800mm concrete foundation, the floor pipe work is done in advance when the foundation work is done.
The site you saw now has only the basic structure of a Hanok, and the walls are made in advance using the paneling method. This is a modern method. Originally, walls of this type were made on site. The way the walls were finished can be said to be a modernization of the traditional method. The inner walls were finished with yellow clay mortar mixed with yellow clay and cement mortar, and the outer walls were plastered with a material mixed with yellow clay and lime cement mortar, and then finished with lime plaster.
The insulation on the roof was rice husk charcoal made from burning rice bran. It is not a commonly used material, but you can think of it as one of the experimental eco-friendly insulation materials in Korea.
4. I think this video clip is a cross-section of the Korean construction market. I think it shows well how eco-friendly and passive housing, and prefabricated construction methods that have entered Korea as Western-style wooden houses have influenced the Korean single-family home market and traditional architecture. When you look at things like rice husk charcoal used as eco-friendly insulation, panelized walls, and 'mokguiyeon' that has been omitted and only the shape remains, I think the contrast between new and disappearing things is clearly revealed.
Ah! The decorative ironwork that is attached to the joint of the gable is called 'jinecheol'. It is used to cover the gap between the gables, and it is called that because it looks like a gable. ^^
I watched the teacher's video clip three times and tried my best to answer the question, but I'm not sure if it was enough.
I'm currently working in modern architecture, but as a carpenter who has been a traditional Korean house carpenter for about 12 years, I'm leaving this long message in the hopes that it will be helpful to the teacher who taught me and helped me a lot.
I hope you stay healthy and happy, and I hope you continue to make great video clips in the future. Thank you.
Check this comment out guys! Great stuff!
I never thought i'd say this, but you, sir, have made the most enjoyable commentary video I've ever watched;
Not much bias, digesting the way they do things, asking questions, thinking out loud, making connections.
Nothing like a pure engineering mindset that transcends the boundaries of culture.
Ditto!
That's actually normal behavior. People have forgotten

9:44 That’s charcoal made of organic rice husk. It helps control moisture and humidity, and keeps pests away.
HTF does it not burst into flames if someone rubs their hands together too fast? JFC charcoal in the roof? It's beautiful and the craftsmanship is unreal but the flamibility factor...
@@michaelposey6529 😂 It’s not a charcoal briquette. This company is not JFC, but 유기산업 (Yugi Ind Co.). It’s an excellent flame retardant material and it follows South Korea’s construction safety standards.
I love construction based on mechanically interlocking.
Rather than fastener dependent.
Gravity holds the planet together. Sometimes limited movement is your friend. More of this content please.
It's why Japanese wood joinery is so interesting
It’s also much much stronger than stick construction. Timber frame really doesn’t cost that much more-30% maybe-but the structural gains are tremendous.
If it can bend it can resist forces that would break it. When we fasten things down to where they can't move, the energy from nature (hurricanes, tornados, earthquakes) has to go somewhere. If it's fastened down, it could break, but limited movement will allow the energy to bend the materials instead. Converting the energy to movement.
@@TheBockenator 30% more is a massive cost increase. Wtf are you talking about? Imagine if your landlord said a 30% rent increase doesn't cost much more.
Gravity holds the planet together. Im mostly not a dummy lol but I have never considered that concept. Cool way of looking at gravity.
Your willingness to look at crafts people from the world outside the US, to learn and appreciate different ways of doing things, makes you a great ambassador for your faith - and very refreshing. Thank you.
Terrific video! I've been all over Japan and as a once framing carpenter, and physics teacher, I poked my nose into every structure I could find. What I notice, might also apply here: Basic Chinese temple structure with some key elements missing (maybe). After I spent two months going all over Japan in 2016 I thought that diagonal bracing wasn't something often done in Japan. I was in Matsumoto a few days after the earthquake there. Saw a couple of collapsed structures. Old buildings, no diagonal bracing. (Windows right to the corner posts) They basically twisted and dropped. In Kyoto I saw a new office/retail building going up in between two existing buildings. No diagonals, but huge steel I beams. In the front where it might be all glass, sure. But on the blind sides? I think the huge steel beams and posts were basically bridge construction to add the rigidity. (I was then teaching at the RFK Ambassador schools in Los Angeles where the main building had huge diagonals. I would show my students out the window where the Hollywood Fault was and never worry.)
In Japan I saw a few old barns and out buildings with the sides falling off, revealing no diagonal bracing. I thought I was learning something about Japan. My basic theory was this was Chinese Temple design taken a step too far.
Last year we docked in Chosi , Chiba Prefecture, just up the coast from Tokyo. Walking around I again poked my nose everywhere I could get away with it... This time I saw diagonal bracing every where I looked. Newer structures. One thing that was different from American framing is the sole plate at the bottoms of the walls in garages. Very deep. Like 10 cm (4 inches) even though they rested on thick concrete footings raised above ground level. This was in garages where there was no sub floor structure. Civil engineering, bridges, highways, train stuff? To international standards, well built and no flaws that I could see.
I'd have to say that as a general theory, my idea of no diagonal bracing isn't universal, but it does seem common. (I've never seen an American with a 16 ounce hammer put of any framed anything without at least tacking in a diagonal.) The basic idea in Chinese temple design is that the timbers are, like the house in the video, well connected so that if there is movement from an earthquake the building structure shifts with the forces but doesn't collapse. In Kobe, Japan many houses collapsed in the mid 1980s quake. The were built without heavy mortise and tenons, with a very heavy tile roof on top, the roofs moved differently from the walls and collapses. (American framed homes do well in part because most of our roofs are fairly light.) A long Shinkasen bridge to elevate the train collapsed in that quake because it was straight for too long, they quickly figured out to solve this problem. (I think some of these bridges they put a few twists, the trains all automatically stop if there's an earthquake.)
If you do Chinese village mud wall construction, I've got lots of photos of buildings in partial collapse revealing how they were built/. People moved to the city, roofs weren't maintained, the walls melted in the rain. All in all to me it seemed like the Chinese even at the most basic level understood the building methods they used.
@trinitytoo -Amen! Good observation and perspective.
Exactly what i tought after the intro. An open mind is a big part of a great person!
His willingness to watch a youtube video. What a joke. I guess he must be enlightened.
@@joeeley5354 Sorry you got coal for Christmas.
I had a home built in 🇯🇵 by a master carpenter and his son. Nails were purely decorative. Their joinery with only chisels was incredible to watch. No cost overruns or surprises. One of the greatest experiences in my life….
But how?! How do they make money without those extra surprises 😂
@@synckid 😂😂😂😂😅😅 always something extra
@@synckid - in my EU country, building contractors generally are very bad at cost calculations and often have conditions that facilitate cost overruns. So when they have a cost overrun, they charge more. Alternatively, fixed time and scope contracts often see quality issues, and fixed price contracts have duration and quality issues.
An account manager of a large bank in the country told me about experiences with contractors as clients in the building industry. Not funny. They could not calculate the simplest projects but at the same time knew they could buy a very expensive car. And next be sent into the foreclosure department.
In traditional building, based on a centuries old tradition, the masters precisely know what has to be done, the pitfalls in the work and site and materials needed and logistics thereof. Making a proposal that works well between client and contractor then is a piece of cake.
In the research world of project management methodology the traditional way of building a house can be classified as a "paint by numbers" type project. It's clear what result has to be delivered and it's clear how it should be done. This takes both result and process uncertainty away. Been there, done that. Hit the ground running. The Gerries would say "senkrecht starten" (vertical take-off - that is, like a rocket).
The man who came up with project risk classification (prof. Eddie Obeng), then distinguishes three other types: "making a movie" (result uncertainty - we know how it must be done), "the quest" (holy grail - we know when we have the result, just not how to get there), and "in the fog" (result uncertainty and process uncertainty). Many building projects start as a quest just because not enough planning went in, and then over time become "in the fog" when between contractor and client scope-changes happen. Such scope changes can be caused by a client changing their mind, but most likely happen when the contractor proposes a change because something turns out not to be available (either because it is not, or really because they assumed a much lower price or waited too long with ordering at a set price).
In commercial building projects we see a large site with a contractor cabin in it and when you look into these cabins, you'll see full time planners working to make sure everything gets delivered in time, and if shift happens, they swap work packages in time to make sure the work continues. Contracts with vendors to the building-contractor have serious penalties.This also means the contractor will review the financial strength of their vendors, because any guarantee is worthless if using it means bankruptcy.
As example of penalties, in my country, some governments when contracting a firm for roadworks, agree on a duration (calendar time) for the project that next is converted into a lease of the involved public infrastructure to the contractor, with the clause that the contractor can charge the government for the duration agreed in the first place. Such projects become a financial loss very quickly due to the expensive rent after the duration. And these projects never run over time.
In other projects we see very long durations that may have been planned as a way to allow the contractor to use "cheaper" downtime to do the work, or as a way to teach citizens other, new to them, routes to commute.
Decorative nails, lmao
@@garvinsimmons the something extra happens when you underbid on a job. When you are competing against half a dozen fly-by-night operations that all use dirt cheap Mexican labor, it's hard not to do.
I was not only impressed by the clever craftsmanship, but also the quiet synergy in which the crew worked. What a high level of economy of scale, organization, and efficiency displayed.
Having worked around the South Korean Rock Army! South Koreans are nothing short of impressive people! They work hard, smart, and make the most of the what they have. They’re amazing and we as Americans could learn a lot.
Over 50 years ago I was stationed in the Philippines. I have since stood in awe of the creativity and ingenuity. The Orient is far more fascinating than the west.
What a thrill to watch

During my time at camp Humphrey’s I remember watching an about 60 year old man put a refrigerator on his back and walking down 6 flights of stairs because the elevator was turned off
please do more of these from around the world. i watch them on my own time but to get your input and thoughts adds to much to the video.
Fascinating. Having studied Japanese carpentry, I expected the techniques shown would be similar, and this is because in ancient Japan, the best carpenters were said to be from Korea and many of their techniques were passed down after their tradesmen were invited over. Kongo Gumi for example, was the oldest company in the world, existing from 578 AD, and was started by Korean temple builders hired by Japan.
Damn that's interesting little tid bit of info!
Japanese culture and arts are largely korean
@@kenadrian27mix between china and korea but in modern time its looks very different, especially in entertainment culture, for huge example like idol culture its start in 1962 in japan and adapted by korean later on
@@kenadrian27 The structural technique shown is a version of 穿斗 carpentry, used in China since the Han dynasty, iirc, where the beam passes through the column and is locked in place by a cross beam, that also passes through the same column.
What do you think Jingoist Chinese folks would think of Korean and Japanese architecture?
It's mean and unnecessary to dismiss anyone's culture, like Japan did to Korea during WWII. Don't sink to that level.
just to add my two cents, from what I can see here in this footage, it's not entirely "traditional." no nail guns or even steel nails were used back in the days (even wooden peg nails were minimally used).
One of the best videos ever. Do more like this, i believe this suits you 100%, commenting of different building techniques
Agreed. Love EC's regular content, but this was really great to watch.
What Mr. Hellenas23 said.
He's got the perfect voice, timing, and input for voicing over it, too. Hehehe
More please!!
Brilliant!
I did Italian plaster when I was younger. Those lads working on the walls DO have strong arms. Beautiful job. I need to show this to my old craftmaster, old man gonna love it. ♥️
All homes are plastered in UK except for these new buildings now . They use chalk and paper boards , plaster boards.
Korean homes, especially the more traditional type ones such as this one, have built-in floor heating. It is fantastic during those cold, brutal winters. (Korea has four seasons to the max, spring and autumn is amazing, summers are humid and hot, winter are damn cold.) This home is beautiful and made with craftsmanship and pride.

@@jamesgeorge4874 There's more to do with climate than just latitude. Korea gets affected by high pressure systems from SIberia in the winter and the Pacific in the summer. I'm from NY and Korean weather definitely feels more extreme
@@jamesgeorge4874 To the north of the Korean Peninsula is Siberia, the coldest in the world. Initially, the United States did not have any supplies for cold weather during the Korean War, judging that Korea would be a savannah similar to West Africa, but as the Winter Front opened, many dead people occurred.
South Korea's Gangwon State begins to snow from October to March, and North Korea's Kaema Plateu is where all the northern hemisphere's cold air currents gather due to westerly winds, so the temperature in the coldest month of the year is similar to that of Anchorage.
The structural engineering of traditional east Asian post-framed buildings is fundamentally different. They tie together the building with a box frame (made of heavy timbers with wood joinery) at the top half like a piece of furniture with legs, rather than using the ground for rigidity, make a whole assembly to spread load out on that box, put a heavy tile roof on top, and gravity plays a big part in keeping the thing together. This gives the whole building a little bit of flex in an earthquake where its center of mass can move relative to the ground without a lot of damage.
Wow!
@@TrogdorBurnin8or strangely enough south eastern American cracker architecture is similar in many respects but because the floor is part of the structure above the pillars they don't need the heavy timbers for rigidity and weight. Unfortunately they face hurricanes so while the flexibility is extremely beneficial they ultimately rely on surrounding trees to avoid being blown off the pillars, but so long as they are surrounded by good trees they have survived countless hurricanes without using anything more than gravity to keep them on the pillars.
I've seen a doc of old Chinese buildings from thousands years ago without using a nail or screw. it was like a big Lego structure that can stand earthquake up to 9.0. Which it still stands today.
@@notchit3542 Japanese temples are that way and with the counterweight pendulums hanging in the center, its amazing how well they do in earthquakes
This explanation makes so much sense, while watching this video I was thinking, ok, the strength comes from all the joints coming together? Because the base seemed super unsecure, so it had to come from somewhere. Fascinating!
A natural stone plinth won't wick like concrete. My church in Virginia was built in 1840 and until recently it had original wood beams sitting on sandstone piers with no hold downs. Lasted 180 years that way - the original beams are still there, too. The only reason it changed is because we had so many people in there and got tired of the bounce house effect so we raised the whole thing to put more bracing & leveling in - but code wouldn't let us put it back down on sandstone blocks, so we had to build a CMU foundation and seal it before putting the church back down on it.
Yes because it was not good enough to last 200 years you have to put it back to code that lasts 30 years :)
😂@@BrianEhrler
Depends on the stone, the temperature, humidity, and airflow I'd say, and if it's cracked of course. Water is a very tricky foe. If it's done right it is very possible. Usually wood underwater or in the dry tends to last, it's when air and water both have access you have issues.
Can I ask where in Virginia?
@@joytotheworld9109 laws arent about the current condition most of the time, rather its about meeting a certain way of doing it, if using a stone isnt included or premitted to be used, then it will fail to meet the requirement regardless of the condition of the rock.

Google translate is not doing a good job here. Need some help please.😂
@kwcnasa Idk man it makes perfect sense to me....
The stone under the pillar is a foundation stone made of granite.
The pillars do not come off the foundation stone because the heavy tiles and the heavy wooden structure press down with the weight of the entire house.
The characteristic of traditional Korean houses is that the eaves are long, and because of these long eaves, the wooden pillars exposed to the outside dry well due to the light and are well ventilated, preventing them from rotting.
On the contrary, the pillars inside the closed structure often rot.
The exterior finish is made of yellow clay, sand, and lime.
In the past, the pillars were trimmed and the remaining wood, yellow clay, and lime were sprinkled before the tiles were placed. but in modern times, ceiling insulation is done using rice husk charcoal.
Since traditional Korean houses use floor heating, they use thick, eco-friendly insulation materials even if the insulation level is a little low.
In addition,
HVAC inside the building is performed by natural ventilation.
Communication and electric lines penetrate the walls and go up to the ceiling, and are distributed above the ceiling.
The bathroom water line is finished by going up inside the separately installed masonry wall, and then the waterproofing process is performed.
There seems to be no explanation for the sewage line, as it is a procedure that has already been performed in the foundation work and is already a widely used method.
As I wrote in another comment, this is very similar to the traditional Japanese way of building. I know that Korea and Japan have a complicated and controversial history of relations. But despite this, they are still close Asian cultures that have adopted many things from each other.
I love the algorithm, this is the best visit (and here to stay) to a new channel in a while.
absolutely loved this video and the commentary. the additional explanations from knowledgable Koreans are equally pleasing
It's silly, but every time I see you confronted with knowledge that you're not familiar with, YOU ADMIT IT and say, "Hey, there's something I can learn." It makes your content so approachable to beginners, like I was, when i first watched your circular saw basics video years ago. I'm astounded that I can be proud to watch and learn from the content you create, even after all these years. P.s. I've rehabilitated a 100 year old school house into my home since I watched that first video, and Essential Craftsman always seems to be my first search when confronting a new challenge.
It's a rare thing to come across these days, and I've always seen admitting what you don't know as a true sign of intelligence. The smartest people I've known will be the first to say they're not certain what they're looking at and then they take the time to learn.
Scott, I liked your voice over. It was like I was sitting here with my brother watching this. These men are truly artists. The quality of the work and design is just awsome, I thought the black stuff in the roof was shredded tires, but I stand corrected after reading the comments. I am digging a bunch of that red clay out from my crawl space. That stuff gets so hard you could build a house without the framing. I have always said if we spent the money spent on wars on doing good things the whole world could have things like this. You started as a TH-cam creator passing on skills, ( as many others) and have become a friend to so many of us. Please do more of these, I really enjoyed it.
Yes, and I think they know that they are artists ;-)
Charcoal rice husks - insulating but also resistant to infestation - the wall panels matts have this as well, whole house is breathable because the natural construction materials
IIRC Similar material is often used in some Japanese construction, particularly crawlspaces that don't need access. Charcoal is added for insect resistance as well as humidity, odor, and insulation as the charcoal is very porous. Not exactly activated charcoal but in the sheer volume they use, it does similarl things. Great video. Definitely demonstrates more broadly a certain economy of construction which lets each trade really focus on their particular skill set.
I think also worth noting that in many parts of east Asia homes aren't so much valued compared to the land they sit on. I dont think most traditional construction methods sit around for more than 50 years without serious preservation like in the case of Temples. Just observations over the years, open to being corrected if I'm wrong.
are they not extremely flamable?
@@narmale if it;s rice husk then no, those things hardly burn specially when they already are charcoal.
Charcoal made of any bio material is very flammable. It doesn’t necessarily light easily but that’s how charcoal grills work.

Sir, I have never watched a video of a house put together BUT seeing how excited you were getting and your joy on reviewing the video genuinely put a smile on my face
Amazing.
I've worked on a lot of houses (always as an assistant but you still absorb everything) and gotta say seeing this come together is a thing of beauty.
Fascinating video. I really love traditional Korean homes. So beautiful.
18:00 Many if not all these Korean homes are heated by radiant heating from floor. In the old days it would've been the fire/heat stoked from the kitchen directly but "new" ones like this will be heated by hot water pipes buried in those (concrete) floors.
Also, broader context, almost no one in the world does residential HVAC the way they do in the US. Traditionally in Europe it's all radiator systems for heat (hot water, shared with the plumbing, circulated through physical radiators mounted to the floor in each room) and no cooling, while in Asia, they skipped right from traditional fuel burning to individual heating + cooling mini split units in each room. The fancy version of that is just combined outdoor units that drive 4-6 indoor units a piece, with super efficient heat pumps and variable speed motors. And all you need to run indoors is a slim little flexible pipe to carry coolant. Almost no one in the world bothers with all the ducting that the US does, and they all get temp per room controls!
Yep, I learned back in architecture history class during school that the Koreans had this stone based radiant floor heating system as far back as the Neolithic era or something. Kinda cool.
@@jyc313
Technically, only Northern Koreans had heated floors; Southern Koreans did not, as the climate was warm enough. It was not until the Little Ice Age of the 13th century that heated floors spreads to Central Korea. And not until the Little Ice Age of 17th century that heated floors spreads to Southern Korea.
However, some rich landowners and the middle class used heated floors even before the Little Ice Age, and Koreans have definitely known about them since the 4th century BCE.
FYI, Northern Korea means North Korea minus its capital region.
Central Korea means the South Korean capital and the North Korean capital, plus one more province to the east.
Southern Korea means the rest of Korea.
@@Isl33p True but, yes and no. There were evidence of homes in the southern parts of the peninsula that had “ondol” flooring, or something similar to it before ondol as we know it today. We just have to safely assume it may not have been used as often as their counterparts that lived more north. The entire peninsula in the winter gets really cold, even in the southern tips.
So you’re not wrong, but also not 100% correct. The classes we took included seminars that focused on East Asian Architecture and guest lecturers on subjects taught the series.
Yes, between the Korean, Japanese, and Chinese, you have a LOT to learn. Remember there a lot of nail free buildings over 700-900 years old over there. Those panels in the walls are like our early wattle buildings - they use interwoven bamboo, paper and wood to create the wattle to provide insulation and hold the plaster. Those beams are interlocked by using mortise and tenon and wood pins. Yes, its a lot like our adobe but with more lime and clay. What you see are the typical pre-fab style homes there. Those beams etc. are cut and fitted in a warehouse style shop from an original design. What you saw was a custom pre-fab home.
I didn't know I would enjoy someone's commentary over a construction build. This was great. It was nice to hear your point of view as an expert. Made construction video much more enjoyable!
Stunning product. Beautiful house.
Seeing entire sections slot together so beautifully is incredibly satisfying. Beautiful workmanship.
Very cool to see these old techniques still in practice! No rebar fixes in the foundation, and no steel brackets on the frame. Just make physics your plaything

This type of construction is art. Loved watching this with my morning coffee.
Hi Scott, I have been watching your videos for years and always found them captivating, even more so since becoming a homeowner, but I've rarely been glued to content on youtube like I have been glued to this one. Watching a master craftsperson watching something unfamiliar and analyzing it is extremely rewarding, even if virtually none of this will ever be part of my own skillset. I have always been impressed by the open and sharp mind you have retained over a long life of work, but never more so than with this video. Thank you for doing this. I hope you can find more detailed clips of skilled work from different contexts like this to comment on. All the best to you and your family for the new year.
i am always envious of how our Asian brothers and sisters treat everything that they do like an art. I hope they never lose that part of their culture.
Don't be mistaken. They do have cold bleak concrete buildings too. Single family homes, especially in the countryside are a treasure and they are meant to look like one.
@@alis49281 oh i know that but you dont see these types of things in the West at all - like the old way of making chalk, ink, blades, etc. Lots of lost professions that we in the West just wont invest in for whatever reason.
@@The_Zilli A lot of it has to do with resources rather than art. Lack of metal is one of the major reasons why Japanese and Korean houses are made through joinery. Iron was an expensive commodity. China is the only Asian country that didn't use nails or iron due to complacency and stagnation. Rammed earth blocks were still the most common method of home building by the end of WWII.
@@brainplay8060 I understand resources are different in many of these Asian countries however that wasnt what i was referring to. As others have posted in the comments, this is not a common construction method however Ive found that only in Asian countries you will find things being produced the traditional way, be it ink, chalk, building, fishing, what not, Asian cultures take everything to the next level it seems. Like look at how the Japanese are with their fish market, etc. That's all, it's very unique and I hope it's something the Asian cultures never get rid of as technology develops.
@The_Zilli @The_Zilli it is one thing to improve methods, another to distort them that they fail their function. Wood frame houses are still built here in Europe, still the same materials, but machines helped and improved it all. (No, US American wood frame is an abomination of what wood frame is supposed to be)
Sure, hand made clay shingles are nice, but what machines make is just as good.
The problem with buildings lies mostly in the materials: not reusable, not even recyclable, some even toxic or cancerous. Currently we are in a revolution where old materials are exploited to their maximum and suddenly we have incredible properties unmatched by concrete.
The Korean house in the Video uses technology for prefabricated elements made with old materials. Where Europe uses willow or hazel, they have bamboo. They even use bamboo where we use reed. The clay and lime plaster looks very familiar though!
About the wood post to concrete issue. Let's go to zig-zag style fence building and moisture. If you put a rock on the ground to hold up a fence post, the moisture will creep up and around that rock and into the post bottom. By stacking another rock on the first you have created a break. The moisture will not creep up the second rock. You can stack two flat ones on the lawn and see for yourself in the morning dew. In the foundation, that support block is loose, making a break. Also they can move around the seating to square up the upper frame. Perhaps the Koreans are thinking along that line. I've been doubling up the sill protection on some smaller jobs (garage, shed, gazebo, garden structure) by adding a layer of asphalt shingle (grit side down) to the strip seal, or two layers of shingle. What really helps is two layers of shingle in the pocket when using concrete "deck-blocks." I've been able to keep my eye on some sitting low to the ground, for over 15 yrs. I think it helps dry things up much faster after rain. Works great.
The wood they use is either Red pine or Korean pine. It is the lumber of choice on the Korean peninsula. In house construction that is.
I love the "work smarter not harder" approach. Very smart and interesting.
Essential Craftsman can be found all over the world...please keep up the good work of showing the craftsmanship of others!
I mean no offense but American standards on average house construction are quite low.
@@mousbleu I would agree, tract housing builders don't necessarily have a good quality build. But there are quality builders out there, we just need more of them.
This is all clay mortar. The outside finish could be coloured lime mortar or mortar made of white clay and white sand. The wall strukture is built without any moisture barrier and is able to carry moisture out and in. For those types of walls it is necessary to use only natural materials like clay, lime, straw, wood, etc. No modern coatings which could add a blocking layer into the wall system.
The white textile on the roof system is just the packaging for the insulation. The one on top of the osb is a wind barrier (one could use OSB alone as well, if you tape and glue it).
I built my house pretty similar to this and worked as a clay contractor for a few years here in southern germany.
😅 Danke für deine ausführliche Erklärung. Bin hier im Allgäu und betreibe ebenfalls Lehmbau, und wollte gerade einen ähnlichen Roman verfassen.
🤔 So the clay walls essentially become a flat vertical clay pot material??
I wonder if the mortar/plaster has any lime in it, or if the lime is in the topcoat only
I was skipping around you tube and was mesmerized by this video great commentary.
YT suggested this video to me. What a gem. How can I not "like", comment, and subscribe?
Everything appeared to be planned and cut beautifully prior…. Even the vapor barriers. Amazing. Good for you learning new things!! Fun video!!!
I love the organization and cleanliness of the jobsite! I was impressed with how fit and healthy the workers looked. Being a plumbing contractor of 30 years I would have loved to see the phases of the plumbing, types of material and techniques. I have done a bit of plumbing in Europe on our properties there and find the differences interesting. Thank You for the look into Korean building, fascinating.
Natural clay plaster and lime plasters breathe and create a much healthier living experience. No off gassing and no moisture issues. These houses feel so much better for quality of life too. Thanks for sharing!
its loam not clay
@@peterswalmen the red/yellow earth has clay in composition. id guess like 30-40%
That's right
The printing wood blocks of the Tripitaka Koreana and the microscopic Buddhist script, created in 1236, are still intact and preserved thanks to this technology
ya as you can see from the comment below in korean if you translate it to english the block under those posts is not concrete, it's cut granite, which doesnt transmit moisture like concrete does. so the granite is the moisture barrier, and a lot more durable of a moisture barrier than anything we'd use in the west. i also think the thing you said cant be dirt is exactly dirt with a high iron content. otherwise i share all your observations and questions. there is a lot to be appreciated in the way this thing is planned and executed and a number of things we'd wanna know before we tried to do anythng like that on our side of the world. suspect if we'd seen the foundation and bottom slab from beginning to end we'd have some answers
Please do more of these. Really a pleasure to watch!
Thanks for this video. I like how the lumber comes pre-cut and made to fit like a glove. Its like putting together Ikea furniture on a grand scale. I am also impressed by the simple drawings, clean work & the neat housekeeping.
Koreans have such a natural beauty in their culture love seeing them do anything ❤❤
This is ridiculous. Hanok houses as we know them today date back to the late 15th century , they did not exist in that style before that and looked more traditional Chinese style.!
That Hanok style was 100% taught to Koreans by Japanese during the Japanese invasion and occupation of Korea since 1595. There were no Hanok in this style in Korea before that.
This is not Korean architecture, this is 100% traditional Japanese architecture !
@Hannari-xt6nr go take your medicine
@@Hannari-xt6nr It's sad that you get trashed on for only speaking the truth. But welcome to the internet.
@@Official-OpenAI This is actually really amusing that people seem to know so little about history at the time of the internet !
Thanks for the comment, i appreciate it. I have nothing against Korea, i just fin d it hilarious that Koreans would consider the Hanok style to be actually traditional Korean architecture.
It would be like saying that the Alhambra in Spain is actually Spanish architecture, it is not, it is Moor architecture. Koreans have a tendency to do what the Spanish do here in Europe, they assume. The Spanish completely forget that they were arabic for much longer than they have been spanish and that spain was under Arabic administration for 700 years. 90% of what we con sider spanish today from Flamenco to Tapas to Paella to the Alhambra to the spanish language itself comes from arabic influence. Most of British and Irish and Scandinavian culture is not western or christian, it is Celt and Druidic. Korea's culture is mostly Chinese just like Japanese culture. Except Japanese have no problem acknowledging how China influenced Japan, but Koreans really have this injured pride thing which makes them act like they built the Egyptian pyramids. That's more funny and ridiculous than it is annoying.
@@chappy3125 You mean my 약 ? Because you see the funny thing is that Korean medicine as well comes from Chinese and Japanese medicine. Isn't that funny !
Just a quick search will confirm it to you !
Make no mistake, i know Korea very well.
In Iraq . The wires are run through the house . Then plastered over with raw gypsum paste . Outside walls are rock plastered over with mortar then painted white .
Scott said it correctly- sustainable but not energy efficient, living in an old Japanese farm house I can affirm that there are gaps between the timber frame and plastered walls, it is drafty hehe
The relief cuts in the ceiling boards are to prevent cupping.
Great video! would love to see more of that style ❤
Cram in backer rod or wool-denim insulation.
Actually these are very energy efficient often meeting or even surpassing modern standards of thermal resistance...
The homes being preserved in the UK that have a similar construction they use a rope made out of wool and dip it in animal grease as a seal between post and panel before putting the earthen stucco to prevent drafts, just like they did back in the day.
Yeah, Japanese didn’t bother with the underfloor heating the Korean’s invented. Korean’s don’t really understand that😂 Korean farm houses are a lot warmer
@@clareryan3843 Yes...The Japanese culture has developed and normative belief in a principle of localized or "self heat" often using something like a 炬燵 "kotatsu." A very different mindset and approach to living that many cultures in the world...
Great video! Love how you are fascinated on their techniques rather than looking down on them for using weaker joints in some areas.
This was such a treat. Thank you for enriching us. Liked, subscribed, and making the rare comment in hopes that the algorithm brings me more content like this. Happy New Year to everyone!

To see a Japanese carpenter build a home I highly recommend Shoyan Japanese Carpenter, I believe he is on his 5th house building series for TH-cam. He dubs all of his videos in English and mostly build timber framed homes built to modern air tightness standards.
Cannot agree more with your recommendation. These two are peas in a pod.
Shoyan is the Best!

@@OldMan_PJ definitely will have to check that out
Spot on. Essential craftsman and Shoyan are two of my favorite channel on youtube. They share the same positive vibe i admire.
Just found this channel and absolutely loved it. Can we get more reactions to overseas construction videos/techniques? It is pretty fun to see someone who has been doing similar work, reacting to the same type of work from across the pond. Asian construction especially because those cultures have some of the oldest buildings on the planet, and they still exist for a reason. In some extreme cases, some have been through typhoons, heatwaves, extreme cold and severe earthquakes for hundreds to thousands of years. Thanks for the enjoyable video.
As a former residential contractor. I've seen Korean residential construction videos before and I am fascinated and enthralled by the building systems and beauty. This was a relatively simple build compared to the curved structures I'm seen built before. I'm a big proponent of simple roof lines and low pitches which, as evidenced by this video can be as beautiful or even more so with the last lasting roof tiles, The US is in sore need of a rethink of our construction techniques. I say all this as someone who is disgusted by the garbage, garage front facade boxes being foisted on US homebuyers.
If Mr. Wadsworth is up to, I think it would be fun to hear his opinion/observations on Shoyan or The Carpentry Life, they are channels focused on japanese style carpentry. And I completely agree, I started watching this channel because of the differences on how we build houses where I live compared to the US, and so far I have learned more than I could have imagined. Merry Christmas!!
Shoyan's a legend!
@TheMansley He is indeed! Happy Holidays!
I know nothing about building, other than having been a home owner and had to fix, repair or replace just about EVERYTHING! I loved the aesthetic of the building. Your questions were the same that occurred to me. This was fun to watch, thk you!!😂❤ Grandma in Texas
🌸Thank you for this video. Your curiosity and respect for something different are really inspiring. Thank you🌸
Great commentary. Thank you for reposting this video so that we can all learn from each other across many cultures.
Please do more of these from all around the world. There is so much to learn for each of us.
this is gorgeous....nothing like australian homes. thanks as always Larry for broadening construction horizons.
Great video. I hope you can do more of these EC! It's actually educational and helps broaden our worldview here which, lets be honest, can be a bit myopic at times in the USA:);).
Thanks so much for this revealing look at Asian construction. I've enjoyed several of your videos, but this one is the best yet.
In the 90's I worked for Roland Schweitzer, an architect in Paris. As a Parisian, Roland Schweitzer came to his love of wood architecture through his love of Japanese architecture, and he hired me in - in part - because I was a Californian familiar with wood construction. I subsequently learned how different the ancient Japanese and modern California methods were. Whether you see it as a good thing or not, the truth is the US is - by global standards - somewhat obsessed with using industrial developments to improve safety. I'm proud of many of our US developments and the US instinct to tinker, improvise and improve things. Still, it also disturbs me that there is often a loss of craft in our industrial approach to buildings. Also, industrial improvements are sometimes implemented for a speculative, gimmicky entrepreneur to make a buck in concert with a code upgrade. The reality is that this lack of craftsmanship and the presence of this entrepreneurial speculation have some safety ramifications, too.
Whatever the case, Roland Schweitzer made sure I understood that many shake table tests have been performed in Asia with posts and lintel construction. What they discovered - certainly not intended to be an exhaustive condemnation of shear walls - is that placing a shear wall between the lintel greatly increased the likelihood the lintel would fall and the structure would collapse. The lesson I was to draw from this experiment was that some flexibility in a structure is valuable in an earthquake.
Our US method of construction is not built around this model. We build rigid structures designed to absorb the relatively unmitigated force of the building's sideways force. The approaches (post and lintel versus shear wall) are very different. While flexible buildings have merits, they are also tough to analyze and have fallen out of modern deterministic favor.
I remember watching the video's for how this house was constructed and I absolutely loved every moment of it. No nail guns in sight for main framing, everything fits together. Wouldn't it be nice if New Zealand builders had the skills to build this way..
Where has this channel been. I’m glad TH-cam finally got it together and recommended you. Your passion for your craft is tangible and your input is so thoughtful and adds to the content you are watching. Nice stuff 👍🏻
I admire how you embrace the artistry of people from around the world, appreciating their unique techniques. It’s a testament to your faith and a breath of fresh air.
I have my gripes about the build as well, but one thing I really admire was the attention to detail everyone had here. I feel like my jobsites are filled with people and subs who just don't care. I've seen roofers blow nails out through the patio and don't bother to fix it, hvac beat the heck out of boots to where you have air leakage issues, and many others. Even the lumber looked so much better and so much less waste than what I buy. I would feel so relieved to have a crew like them building my client's homes.
Western construction methods give so much structural strength that you can get away with using mediocre wood. Joinery cannot say the same. The box frame design requires high quality wood cut to very exact measurements or risk serious failure.
The lack of quality control that we see with a lot of developers is due to poor management who aren't actually supervising and reviewing the work. Easier and less costly to hide it than replace and redo something.
Much construction in America is very degraded by greed. Pathetic people hired for cheap wages and unsupervised. No pride. No integrity. Then there are also high quality builders. Probably the same all over the world.
@@jimmock1155 With tract homes and national builders I tend to agree, because their focus is on fast and "cheap." As a gc who builds custom and semi-custom homes and is there working with basically every crew everyday I'm still noticing quality has dropped dramatically. The subs I used, know and respected over the years eventually hire newer workers. The older guys I trust retire or go on to be supers, and newer guys take their place. Unfortunately, as a early 30's millennial myself, I'm disgusted by my generations work ethic. While many just need more training and work experience, most do not ask for help and will bash their way to the end of the day, get paid and dip. My job has become a babysitter and it feels demeaning because I want to be their to assist and build a home my clients love and now I've turned into a full time inspector/judge. I hope it changes, I really do, because even the subs throw their hands up at this new work ethic and are still ending up calling in the old guys to fix the mistakes.
This could be a video series a really successful one of going the different countries learning how they do first hand from them with the Foreman telling you how it's done.
13:44 Gravity does not hold the field together. The edge and ridgeline are fastened and the interlocked field creates unified mechanical strength. Like binding a layer of boxes on a pallete with a ratchet strap will let you pick up the whole layer and while the boxes in the center of the layer hold their place by shearing friction, except this is even stronger because of the interlocking of the field.
But if you turned it upside down they would fall out so......
@ryandekalands3842 Nope. As long as the outer edges stay bound the inner field will stay interlocked. And if the roof gets flipped upside down you got a whole lot of bigger fish to fry xD

Thank you good sir.
Its so heart warming to see how much excitement and passion Scott shows when watching this video and learning about it. Thank you so much!
While not designed to resist earthquakes, hanok’s lightweight and flexible construction can actually help absorb seismic shocks, reducing the risk of damage. Thats the reason they dont tie structure to the foundation
...so it is designed to resist earthquakes
Something quite applicable to the Pacific Northwest
I guess they don't have hurricanes there.
@@SingleStackedfrom what I saw their typhoons are MUCH more gentle than hurricanes... But they are in mountains so flooding and landslides are the problem not the wind.
@@SingleStackedTyphoons sometimes. But most of them will be quite weak while reaching Korea.
I am an expat living in the countryside here in South Korea and the level of craftsmenship and materials is far superior to some the stuff the US uses. I have a half hanok style house similar to the house in this video. It will last centuries compared to a North American home.
If I'm ever lucky enough to have my home built, it will not be a made by HomeDepot house.
Posts look like hard stone, like granite. Insulation looked like carburized rice/wheat husk.

Whoa. I am, at once, amazed and also not surprised at all to see this type of craftsmanship being used on this part of the world. I built a kitchen island for a client once using basically the same technique. Totally out of my comfort zone, but the client was on board and I just picked away at sorting out where to put what kind of joinery. Castle joints on top where the aprons all tied together, draw bore tenons holding the stretchers together, and dovetails holding the interior stretchers together. They did this exact thing, except bigger, and better, and proooobably quicker too😬
I actually looked up how to call Hwang-Toh (황토) in English. It's Ochre. It's the yellow dirt-like material that was applied to the wall. You were curious, and I was, too :)
Great video idea about doing building techniques around the world… You got me hooked Scott!
Good morning merry Christmas, you would be surprised how construccion takes place in other countries, for instance Mexico 🇲🇽, I know a little about construccion and you would have a heart attack about how a lot of houses are built here where I live, specially because regulations are not followed, I wish I had enough money so I could hire you to come down here and help me build a house, God bless you and your family.

@10:00 - side of the bag - "Organic rice husks"
Yep, it's rice husk charcoal.
@@gavinhay6627😮 so even the rice hull is burned ( Shou Sugi ban?) (forgive my misspelling) to keep it from rotting??
@@THE_BaconPirateyes it prevents insects as they do not like pure carbon. And yes, if a fire source were to start it would generally not propagate unless there was another fuel source. The material is not dense enough and doesn’t have enough unburied material on the outside to hold a flame unless superheated. And I believe it’s essentially the same material sandwiched inside the wall segments.
Like in the US, the description [organic] must make it better, something like organic leather.I appreciate organic food, it is better.
@@218philip - Organic leather! Clearly better. Like "Corinthian Leather" in the old Chryslers when Ricardo Montalban was pushing them (it was a 100% fabricated marketing thing!).
I love this construction it's like Lincoln logs.
20:05 the plaster is clay, it's actually dirt and the top coat outside was probably lime
Clay like it was used on half timbered houses here in europe. It gains popularity as it is a breathing material for unique room climate because its not a moisture barrier.
I find your presence very comforting. I am a building enthusiast, never got a chance to go to school for architecture. This is very nice content. Thank you!
No saw on the sight because everything was precut at the factory! Fits together like Lincoln Logs! 😊❤🙏Beautiful work!
Fan of your channel. Appreciate the new perspective. Would be great to see you get out a bit more. There’s a whole ‘nother world out there beyond 2x4, plywood, and drywall when it comes to house construction.
Lol, how ignorant do you think he actually is?
You need to take a trip to see it live… then go to Scandinavia and check those guys out…. Will blow your mind :)
Oh man yeah. The Scandinavians are probably the best builders in history.
It's timber framing.. It's not too common, but timber framing is done in the US.. I'm quite sure the typical Scandinavian methods are similar to what's done in the US. In fact, I'm sure there's inspiration from there in the US.
Id assume older countries would have more experience in building. Love to see it all.
? Clay lime sand that lets walls transfer moisture in and out, similar to hempcrete would be my guess.
Great show as always, my brother. U have brought to the forefront what having an open should be.
That roofing insulation translates to "Charred rice shells"
The weather on the Korean Peninsula is harsh. Its annual temperature range ranks within the top 5 globally. The difference between seasons is extreme - summers are hot and humid while winters are cold and dry. Even people from Africa say it's hotter than their homeland when they come to Korea, while Russians say it's colder than their homeland. Moreover, there is a monsoon season that doesn't exist in Western countries. Korea's summer monsoon rainfall is ten times higher than Europe which evenly distributed precipitation pattern throughout the year.
Understanding these climatic characteristics helps us to better understand traditional Korean building techniques. Traditional Korean wooden buildings (Hanok) originally did not use nails at all. Instead, they used joining techniques to fit wood pilllars together like 2:28 which allowed the wood to expand and contract naturally with the wild changes in humidity. There are said to have been around 80 different types of these techniques.
12:55 The traditional roof was originally structured with alternating male (convex) and female (concave) tiles, and their placement were carefully designed to withstand the massive rainfall during the summer monsoon season while ensuring proper drainage, and the angle of the eaves was carefully adjusted to ensure proper drying of the woods in the sunlight.
The ondol (floor heating system), which wasn't shown in the video, was also a product of adaptation to these environmental conditions. While times have changed, Western construction methods have been adopted, and materials have evolved, the climate remains unchanged. Korea's environment, which requires adaptation not just to one distinctive season but to two extremely different seasons, became a major reason for developing construction methods different from those in the West.
So those bags of back material that they put on the roof were rice hulls/husks that have been turned to charcoal..... and the wall panels are also rice hulls/husks, (but not as charcoal LOL) I THINK .... we didn't really get to see it close up, but I've seen them being made, and they wrap them in a thin sheet and it's all sewn together... and there are piece of bamboo sort of woven together around that, and then the mod layer is put on that... the bamboo is used to help hold the mud on.... I saw how they do in Japan and have been under the impression it's essentially the same in South Korea, but I'm not expert on Asian House Mud lol 0 I really fins it all just so fascinating.... but you will should look into the South Korean tradition home heating systems... it really is ingenious and incredible!
