I live in Normandy and spend most summers re-pointing in natural lime and repairing the colombage (mud,lime,cow dung infill) on people's properties. Absolutely love restoring something that's been attacked by ciment and silicone, and putting it back to how it should be.
We bought an apartment in a timber framed building in Bergerac and learned a fascinating fact. Centuries ago they used to transport goods up and down the Dordogne on floating vessels called gabarre and when they'd finished with them, they were dismantled and all the wood was used for the timbers in the buildings. Amazing
Interesting reference to the 'gabarre' as the Scots word (in 17th c. Ayr at least) is 'gabar'. Ayr, on the west coast of Scotland, had considerable trade with France for centuries.
The 16th century timber frame building was the outcome of thousands of years of experience. With people building houses and applying not just local materials, but the technology and knowledge built up over centuries.
In terms of overhang for protection of the building, that is true regarding the roof. The overhang created by the joists for the first floor are overhung to facilitate smaller timbers to be used over a wide span. The overhang counter balanced the internal floor weight. (Thing of the seesaw principle.)
Interesting Roger, as always, one thing is for certain the new builds by the developers will not last anywhere near as long. Had to get that one in, 😂, plus they have zero architectural merit or charm. For all the supposed advances in building technology, it’s now a rather inferior result. And breathability is the key definition, and Lime is an absolutely essential ingredient in mortars & renders absolutely avoid cement rich mortars, we used to gauge our lime mortars according to aspect. That is, if deemed necessary and depending on exposure we would add a proportion of Portland White to the mortar mix but the mixes were always lime rich. And when using Lime mortars never use builders sand it has to be sharp sand to maintain the voids in the mortar hence its resistance to cracking. I’ve been back to jobs we did many moons ago & all is sound. Lime great stuff.
So true about the DPC, we live in a 300 year old thatched cottage and we’ve just had to replace two rotten sole plates and this was due to cement being used on a course of bricks underneath, if lime had been used, I think it may have been okay, put the cement had rotted the bottom pieces of timber like you wouldn’t believe.
@@nonoyorbusnessmaybe not even 5 because new houses are built with flammable and light types of wood, they could easily go up in flames if a dumb person starts a kitchen fire for example
Great video, pretty houses. This is why i'm dead set against the coming "retrofit" revolution - it's going to ruin so many homes with people changing the specifications of these buildings beyond what the designer ever anticipated. I know that we have to save energy, but there's not really any point in saving energy if all the built heritage falls to bits/rots.
retrofit can work provided it's done sensitively with compatible materials, though of course the first strategy should always be preventative maintenance...
I'm surprised the dampproof course was a problem. In the US there's a metal flashing between the stone foundation and the timber frame (as a termite shield), and we frame EVERYthing with timber.
Hi Roger, loving your videos!, i live in a 1650 water mill and need to blacken up/restore the oak timber frame, but having trouble finding an answer on what to use, and advice gratefully received, Mick
Good old Portland Cement, he's never far away from rotting timber or trapped moisture is he? I'd love a video on the history of Portland Cement and how on earth it managed to gain such prominance so quickly? Early example of corporate interests perhaps?
It is easy to work with and you can build a lot faster. I don't think it is a bad thing per se, I just think it needs using in a weaker concentration and with lime to give buildings a bit more movement
Perhaps the sole plate issue goes even further where it was possible to get air right underneath that by using overhang foundations to sit the uprights on, with the sole plate mounted to the uprights not the ground via the founsations, keeping all wood and infill dry. It may be a mistake filling that in too much at all if it's not structurally necessary , , they were heavy wood but that's for the wall weight above them . You can form a tacit seal to a thick wall by not filling that ( now hidden ?) vent under the sole plate in.
"they just used whatever they could find"... and some of it lasted for 4,5 even 600 years.... yet with all the transportation of materials and "scientific advancement", the modern house will last 50 years if you are lucky.... 400 years will grow a multitude of huge oaks... sounds fundamentally sustainable... as long as you plant some trees.
Another interesting video Roger, correct me if I'm wrong, it was always my understanding that they built overhangs to increase floor space without incurring extra taxes on ground space back in the days.
I paint bitumen on sole plates of my stud walls, plastic dpm in my opinion can sweat and hold water onto the timber, especially if you have had a leak from above or a flood,
It's the "tannings" the oak contains, it may also have something to do with the organic compounds in the oils what where used to protect the oak reacting with them too Abit like what Rodger said about iron fixings
I just read a book about social planning after the war Austerity Britain 45-51 by a fella called Kynaston. (My commie ex girlfriend gave me it) In one part it describes how architects and planners were told to design properties to last 15/30 years. That way they could be done cheaply, quickly and also keep the economy going with endless repairs and renovations. I'm not sure I think it was a good idea in the long run. But I'm just a humble wood butcher, what do I know
I would have thought that was self evident. We are talking about external walls here. The dpc is better in the brickwork and not directly under the timber.
Skill Builder Elves I had a customer with a south facing lounge terrible dormer above. Knocked it out extended the upstairs over the lounge by 600mm Triple floor joists right beck into the building as a counter balance. 2 results less glaring sun in the lounge and larger bedroom and en-suite Happy client oops 3 results. Planners could not see the idea at first.. That was where the stumbling block was, the Penny did drop and they were Oh we see now!
My guess is that brick most often would be an expansion later on. Otherwise, the brick with timber would be simply cost saving- like putting in windows is done to save dough on a new brick building in modern times.
not my expertise at all, what you just said is all I know about it know ;) was/is limed oak just a fasionable thing or did it have perpose. that shop front looked slightly limed or paint stripped, might of just been a hipsters shop.

Hi John
I was there a couple of weeks ago, what a pity I couldn't film you.
@@SkillBuilder Currently working on a building built in 1069, will be there for the next year, welcome to pop over any time.
Great offer there Roger! Would love to see John in action. All the best to u both.
@@SkillBuilder that is for another video! 👍
Oh wow! Don't suppose you travel to Bergerac? Got rotten timbers galore here! 😟

@@JamesBrown-mt5ru wow! Coincidentally, the guy we bought it from was Scottish! And so the trade continues😄
Peter Ward has a word or two on this subject👍
Nice one Roger👍
Love your travels around exploring the old style buildings, Roger-baby. Too bad you're not doing enough of them.
We have more coming
Thanks Roger! Watching from America, there is a great joy in getting a peek at UK structures. I appreciate your channel
Glad you enjoyed it, we are mindful of those watching from abroad and try to put in a little bit of local colour.

We can't say that our 'new builds' will last 500 years.
5 years, yes!

I thought it was for when they slopped out in the mornings the front door didn't get covered in the proverbial.
La Dolce Vita You are right, it was a land grab
I paint bitumen on sole plates of my stud walls, plastic dpm in my opinion can sweat and hold water onto the timber, especially if you have had a leak from above or a flood,
Something I've always wondered was what made the timbers black?
It's the "tannings" the oak contains, it may also have something to do with the organic compounds in the oils what where used to protect the oak reacting with them too Abit like what Rodger said about iron fixings
There's a process called charring
where in essex was that rodger ,seen stuff like that round the thaxted area
The pictures came from all over. Thaxted was where I did the course.
Get some O'Keefe's Roger!
I have some
Half timber ... used to call em _gingerbread_ . 😁
England and Normandy are the same. Normandy is not french.

I'm not sure I think it was a good idea in the long run.
But I'm just a humble wood butcher, what do I know
It's standard practice to put plastic between wood and masonry. It's just not a good idea when the timber itself is exposed to the weather?
I would have thought that was self evident. We are talking about external walls here. The dpc is better in the brickwork and not directly under the timber.
The old saying is that they don’t make them the way they use too
Yep, that cow dung can last forever, almost as long as horse shit. 😂
Skill Builder Elves I had a customer with a south facing lounge terrible dormer above.

sorry roger! no d
Maybe the question sounds stupid, but if they had bricks, why didn't they just make the houses out of bricks?
My guess is that brick most often would be an expansion later on. Otherwise, the brick with timber would be simply cost saving- like putting in windows is done to save dough on a new brick building in modern times.
Always makes me cringe when I see people wrap joist ends or the like in dpc. Just creates the absolute perfect environment for rot
not my expertise at all, what you just said is all I know about it know ;)
was/is limed oak just a fasionable thing or did it have perpose. that shop front looked slightly limed or paint stripped, might of just been a hipsters shop.
Absolutely ZERO videos that show a tour of these things.
