This series is one of the most clear and informational guides for above ground pools on this platform. Very well done and it's MUCH appreciated.
Thank you very much.
Norman
I couldn’t agree more with the other commenters! I did a partial deck for my mother n law last year after watching this video. This year I will be doing my own! This is literally the most informative video across all platforms!
Thank you for your work and time you out into creating this video!
Rebecca,
I appreciate the nice comments and thanks so much for watching my video.
Norman
Awesome series. I just built a deck for an above ground pool using your exact method. I only had to build two support frames as it was only a small section of the pool. Your instructions were perfect and had every detail I needed. Because of that, took me less than 2 days to build the deck, cut the stringers and install steps. Thank you for this.
Amy,
Thank you for so much for watching my videos. It is really great you had success building your pool deck!
Norman
I am so glad to have found this tutorial. It is the clearest and most detailed video that I have seen. I am going to tackle this project for my 15' round pool this weekend, and feel more confident about it now.
Awesome! Thank you!
Feel free to ask me any questions once you get started, I will try to answer if I can. I hope you will have success in building your deck.
Thanks,
Norman
Out of all the videos on TH-cam you are by far the best thank you the way you teach my toddler could do this your so awesome thank you so much for making this video
Thank you!
Norman
So very welcome
Thank you for making an amazing step by step video...better than anything else on this topic on TH-cam!
Ricardo,
I appreciate you watching my video and the nice comments.
Thanks,
Norman
Thank you so much for the excellent videos and the question you answered about the details for the 24 ft round pool. I was trying to figure the math then I saw where you answered the question. Starting this weekend!!
Glad it was helpful!
Thanks for watching my video!
Norman
Where can I find the dimensions for the 24 ft I am lost and need help lol
This is so cool! I am getting an above ground pool next week and someday hope to have a deck completed
Kitty,
When you start your deck , you can ask me any questions if you need help.
Thanks,
Norman
Great video.
Glad you enjoyed it
Very descriptive!
Thanks
Norman
Hi Norman, Could you explain the compound miter cut for the diagonal braces parallel to the pool? We are having issues figuring out the cut to make it work.
Katie,
Clamp an uncut 2x4 a few inches past the top of the 4x4 post just above the bottom of the trapezoid frame, clamp the other end just above the perpendicular brace near the bottom of the next 4x4 post. Once the 2x4 is in the correct position, use a pencil and draw a line on the 2x4 using the center of the 4x4 as a guide, this will be the top angle, the other end of the 2x4 will be cut at the bottom center of the 4x4 post, use a square, place on the center of the post and draw a line on the 2x4; this will be the bottom angle. Remove the clamps and cut both ends of the 2x4 on the mark. Install the top end of the 2x4 first, clamp the bottom end of the 2x4 to hold in the correct position, hold the top end of the 2x4 on the center of the 4x4 post and install two screws, make sure the other end of the 2x4 is still in the correct position, install two screws.
Follow the same procedure for the remaining braces.
I hope this helps,
Thanks
Norman
That is an incredible deck build and very well explained! I was looking for a build that used the deck blocks when I saw this. I have a 12x24 rectangular pool and I'm only going to build a portion of a deck down each of 2 sides, but I was wondering how long I could make the support frames in that scenario? The deck attached to my house uses support posts every 6 1/2 feet, but those posts are buried. Do the deck blocks limit the length I could build each frame, or is 6 foot between posts viable?
If you are using 2X6 support boards and 4X4 posts, I suggest the spacing between deck blocks be 4ft. The maximum span should be no more than 5ft.
Local building codes may require 2ft. spacing when using deck blocks. I would check and make sure you can use deck blocks for support before proceeding with your deck plans. Thanks for your comments and have fun building your deck.
Norman
@@NormanGooch Thank you for your prompt and succinct reply. I bought the materials last night.
This is the greatest tutorial I've ever seen, thank you so much! I am building a 3" deck just like this for our 24' round pool that is recessed, except only for 5 pool wall sections. We want to do terraced steps the length of it so I'm wondering if doing the sections to match the 5' pool ribs would work with your plan? I'd be so appreciative to get your thoughts, please! Thanks again!
Bekki,
Before constructing the trapezoid framing, build 2 trapezoid templates out of 2x4's the size needed to match your pool's ribs. View my Part 3 video update to help you lay out the templates around your pool.
The trapezoid framing shown in the video will not work using the same dimensions.
When you change the width of the deck from 36” to 60” it alters the entire structural dynamics of the deck and the trapezoid frame. Building codes may not allow this size deck to be built on floating deck blocks, you may have to set the posts in concrete.
Check your local building codes, if they are allowed you will need to double the center support board and add two center posts to the trapezoid framing. Due to the size and weight change, you will also have to use construction screws to connect the trapezoids, connect to the top of the posts, and when attaching the diagonal bracing.
Additional diagonal bracing may be required.
I hope this helps you with your project.
Thank you for the nice comments and for watching my video!
Norman
Thank you so much for your response!! Now if only I were better at describing my project! Lol We are doing 36" deck , but I meant 5' trapezoid sections to match ribs/posts of the pool.
It's only going to be 26" off the ground because the pool is recessed so I'm hopeful the blocks will be sufficient (with diagonal bracing) I will definitely do as you suggested with the 2x4s, that's a great idea.
@@NormanGooch Well we finally finished it! I have to thank you again for the information you shared and how detailed it is. I couldn’t have accomplished this without it! We changed several small details to fit the specifics of plan I created but the thanks is still all to you. I only wish I could share a photo here to show you how it turned out! I made a short of it...hopefully you can view this link to it. Thanks again!!

Bekki,
Great job! Your deck looks nice. Looks like you used Trex decking. Very professional. Thanks for sharing your video.
I hope you can enjoy your deck for many years.
Norman
Hi, I hope you would answer a question for me. I love this idea for a deck and my pool is 15' with 10 sections. Would I use the same 10 degree cut? It seems in my case each section is 36 degrees so I was wondering if I should use an 18 degree cut? Thank you so much for your advice.
Amy,
You have to use 10 degree cuts if you are building a trapezoid framework no matter the circumference of the pool.
I built a round deck for a 15ft pool and have the dimensions I used. If you need them let me know.
Thanks,
Norman
Hi Norman! This video has quite a few years on it's back, but is still gold, thank you so much. Trying a partial version like this over here in Germany and I am wondering about the corner brackets and the joist hangers.. as the trapezoids don't have right angles - how did you make that fit?? Anything that works as a support in the corners is sold as right angles.. How did you do it?
Miriam,
The standard corner brackets and joist hangers will fit the trapezoid frame. Just place the corner brackets in each corner and secure with screws. They will spread a little to fit the corners. The joist hangers will install the same way on each end of the center support boards.
Thanks for watching my video.
Norman
It will be ok to start on the right but you must make sure the dimensions are accurate and the angles are correct especially if you have to build a different size trapezoid over the equipment panel, or as you add additional trapezoid frames, they will not line up properly and follow the correct flow around the pool.
Also, the round trapezoid design makes the structure extremely strong and safe. If you do not connect a complete circle around the pool, you will have to build additional support framing at each end of the deck. You should dig footings and set post in concrete if you plan on building a partial circle.
The reason a trapezoid design is safe on a floating foundation is because any force applied to the deck in any direction, the force is spread out to all 18 trapezoid frames. The trapezoid frames are connected to each other in a circle with no space between the frames, this eliminates any movement of the frames. When the beginning frame and ending frames are connected, it completes the circle.
Thanks
Norman
Hi Norman, Thanks for your detailed videos! We are doing a semi-circle around our pool. Would we need to make all of the footings be set in concrete or just a few at the end? Any details on additional support framing that you mention would be needed?
@@katiek6323
You will need to set all posts in concrete for a semi-circle. Also use construction screws for support instead of deck screws. Make sure you check your local building codes for specific instructions on spacing and hole depth..
Thanks for watching my videos.
Norman
Norman, if I want to build a similar setup but a wider deck than 36" (boards #4 &5 length).... what would you recommend? Prefer to be out 72" from the pool walls. Wondering how that affects the cutting template you have for the support boards.
Mike,
Unfortunately, you can't use the same build details shown in the video for the 36" deck build. Changing the size of the 36” deck alters the entire structural dynamics of the deck and the trapezoid frame size. When you change the width or length, it changes the trapezoid geometry completely.
The size deck you are wanting to build will require:
A new trapezoid size calculation.
Additional framing support.
The 4X4 post will have to be set in concrete footings.
You will have to use construction screws for framing.
You have to add additional 4X4 center support posts.
You will have to add additional bottom frame support.
Additional railing posts may also be required.
Check with your local county building code department and get the deck construction specifications to make sure you follow the building code before starting the build process.
I hope this helps,
Thanks,
Norman
Just curious as I get ready to do my own based on your awesome video.... I have a 30' round pool. Does that 10 degree cut differ with the larger diameter pool? I would think it may decrease but not sure about the geometry there.
The 10 degrees will be the same only the board length will change for a larger size.
Make sure you build templates first and check the fit before you build the trapezoid frames.
Thanks for watching my video
Norman
At 7 minutes 19 seconds into this video, my husband pointed out that the bracket on the center of the trapezoid looks different from the brackets on the top and bottom boards. Did you use something other than standard corner brackets? Something like joists brackets, perhaps, which would go under the center board of the trapezoid for central support like it appears to in the video? Clarification please as the brackets do look different. Thanks.
Yes, after the second round pool deck I built , I used two joist hangers on the center support board instead of the corner brackets. You can use either one for support. The reason I changed to the joist hangers is because it takes less time to install and build the frame.
Thanks,
Norman
I have a islander pool from Secard pools that comes out 18 inches of the ground on wood frame. I want to do a concrete deck, will the wooden frame be strong enough to hold the concrete
No, it is not recommended to pour a permanent concrete slab/ overlays over wood. The framing structure to carry the weight of the concrete is a specialized process using a specific engineering technique.
Thanks for watching my video!
Norman
How do you calculate the building adjustments for a 27 foot round pool. Do you build sections the same size
John,
You can build a round deck for any size pool.
You have to calculate the circumference of your pool to get the number of feet around the pool.
But you can’t just walk around and measure the distance. It must be calculated.
The equation for the circumference of a pool can be written in two ways:
C = 2πr
C = πd
Where: r represents the radius of the pool and d represents a pool's diameter.
The radius is the distance from the center of the pool to a point on the edge of the pool and the diameter is the largest distance across the pool. The diameter is always twice the length of the radius.
When calculating the circumference with a known radius use the first version of the circumference formula shown; when the diameter is known use the second version of the circumference formula shown.
If you plan to build a trapezoid-style frame - the angles on the trapezoids are 10 degrees.
1. Calculate the circumference of your pool.
2. Calculate the trapezoid size needed to cover the number of feet around the pool. (Based on the circumference calculation)
Once you complete the calculations, build two trapezoid templates out of 2X4’s. Layout the templates around your pool, test the fit, make any size adjustments needed, and test again.
It takes 18 trapezoids to complete a circle, the 18th trapezoid is custom built to fit the distance between the equipment panel and to connect to the 1st trapezoid frame.
Once your template layout is right, then you can build 18 trapezoid frames 17 all of the same size based on your calculations, and 1 trapezoid frame custom-built. (Trapezoid #18).

I hope this helps
Thanks,
Norman
I have another question i have the same pool buts 24 foot and only want to go avout 32 around it should i cut your material list in half or what do you think
Ralph,
You can build a partial deck around your pool but you can’t use the same build details as shown in the video.
If you do not build a complete circle around your pool and connect all 18 trapezoid frames, you lose the deck’s structural integrity.
When you connect all 18 trapezoid frames set on 4X4 posts in a 360-degree circle, any force or pressure is spread over all frames no matter which direction the force or pressure is applied. Each trapezoid frame structure will push against each other making a very solid and stable deck frame around a pool.
When building a partial circle, you have no support on each end of the deck frame. Nothing is stopping the deck frame from moving right or left. The deck would not be safe on a floating block support system.
Building a semi-circle or any size partial circle using trapezoid framing will require posts set in concrete, additional support framing, and construction screws used in the frame build.
There may be other requirements as well, check with your local building inspector’s office for code requirements in your county and state.
I hope this helps
Thanks,
Norman
Can you math out the supply list for a 24’ round?
Materials List For 24 ft - 3ft Deck.
The circumference of a 24 ft round pool is 75.382 - Based on the number of square feet use the measurements below to build two trapezoid templates out of 2X4s.
The size trapezoid needed to cover the square feet around the pool:
Board 1 - 38 ¾
Board 2 - 44 ¾
Board 3 - 51”
Board 4 - 36 ½”
Board 5 - 36 ½”
Building the trapezoid Frame
Make sure you cut boards 1-2-& 3 at a 10-degree angle on both ends.
You will need: 3 - 2X6 boards to build one trapezoid frame.
From one 2X6X8 cut boards 2 - 3
From two 2X6X10 cut boards 1 - 4 - 5
Below is a suggested list of materials to build a 3ft deck for a 24ft pool.
36 - Concrete Deck Blocks
18 - 2X4X8
36 - 2X6X10
18 - 4X4X8
66 - 5/4-in X 6 X 12 Deck Boards
72 - Corner Brackets
72 - Joist Hangers
2 ½” Deck Screws - 5 Boxes
1 ½” Joist Nails - 3 Boxes
The above material list does not include the custom build for the 18th trapezoid frame, deck railing, steps, or boards to enclose around the bottom of the deck.
Build Templates First!
Build two trapezoid templates out of 2X4’s. Layout the templates around your pool and test the fit, make any size adjustments needed, and test again.
It takes 18 trapezoids to complete a circle, the 18th trapezoid is custom built to fit the distance between the equipment panel and to connect to the 1st trapezoid frame.
Once your template layout is right, then you can build 17 trapezoid frames all the same size and 1 trapezoid frame custom-built to connect to the first frame. (Trapezoid #18).

@@NormanGooch I didn’t even expect this reply! Thank you sooooo much Mr. Gooch, much appreciated!
Will the dimension of the support frames be the same for a 24 ft pool?

Do those blocks pass building codes? I thought you had to bury posts to below the frost line with footer.
Troy,
They are approved in certain parts of the US. Each state and each county in each state have different restrictions on floating deck construction. Usually states where the frost line is more than 18 inches will not allow deck blocks above the ground. Any time you plan a deck construction project you must check with your local building inspection department to make sure your plans meet code. Where this pool deck is built, the above ground deck blocks meet county building code.
Thanks,
Norman
Most likely if you live in the city limits there will be more restrictions and building codes if you live way out in the rural suburbs you can get away with it.
just an awesome very helpful video , thanks so much Norman for taking the time to put all your knowledge together to help others like myself. Question ? do i need a table saw or just mitre saw or both ? i have a 24' round pool do i need 23 support frame created ? thank you !
Eric,
You will need a circular saw and It would be much easier if you had a miter saw as well to cut the angles needed throughout the deck build. Even though you can cut the angles with the circular saw, the miter saw will be much faster and more accurate.
Adding extra trapezoids will not work. The trapezoid size will need to be changed.

If you are not sure how to calculate the trapezoid size for your pool, the calculations below will give you a starting point.
Since I have not built a 24 ft. round deck and tested the trapezoid size, I can only give you suggested measurements to use for your pool. All calculations need to be tested first, before building all 17 trapezoid frames.
The circumference of the 24ft pool is 75.382ft
Based on this number, build two trapezoid templates out of 2X4s using the measurements below:
Look at the Part 3 video for the board diagram number.
Board 1 - 38 3/4""
Board 2 - 44 3/4"
Board 3 - 51"
Board 4 - 36 ½”
Board 5 - 36 ½”
Test the trapezoid templates and make size adjustments until you get the measurements right before you build all 17 frames.

@@NormanGooch do you see any problem building a 6' privacy wall using 4' decking and 2 ' lattice instead of a railing ?
@@NormanGooch thanks so much :)
Eric,
If you change the width from 3ft to 4ft you cannot use the build instructions shown in the video. Extending the width changes the structure significantly vs a 3ft deck.
Floating deck blocks may not be allowed, you may have to set the post in concrete, add additional support, use construction screws for the deck framing, attach railing with steel post supports (no half-lap joints allowed), and add additional diagonal bracing.
The trapezoid frame will need to be reinforced with 2 additional 4X4 posts on double center supports. You must use construction screws to build the trapezoid frames.
Check with your local county building code department and get the deck construction specifications to make sure you follow the building code before starting the build process.
If you decide to build the 3ft deck, you can add lattice panels to the 3ft deck railings. However,
Half-lap joints are no longer allowed in most counties. Use steel post connectors to attach the 4X4 posts to the deck framing.
I hope this helps,
Thanks,
Norman
@@NormanGooch sorry , no i would like to replace your 4' railing with balisters with a full 6' privacy wall :)
Any idea what the board lengths would need to be for the trapezoids for a 24 foot round pool? I tried doing the math, but my numbers don't sound right. I'm getting about 47.5 inches for board 1, which is bigger than your suggestion for a 27 foot pool.
I can’t seem to get the dimensions right either. I have no idea what to do
Casey,
I have not built a 24 ft round pool deck. After calculating the size trapezoid needed, you start by buiilding two templates out of 2 X 4"s. Lay the first trapezoid support frame to the left of your equipment panel and the second trapezoid support frame next to the first. Make sure the front of the support frames are at least 2 inches from your pool’s top rail. Place a stake at each end of the trapezoid support frames. (wide ends) 3 Stakes.
Move the two trapezoid support frame templates to the next position.
Place a stake at each end of the trapezoid support frames. Making sure you stay 2 inches from
the pool’s top rail
Continue moving and staking the ends of the support frames until you reach the right side of your equipment panel. That should be 17 support frames to this point.
Make sure the trapezoid support frames are forming the correct circle around your pool as you go. Look at the stakes they should flow evenly around your pool.
This is only a suggestion on the size of trapezoid you should start with for a 24 ft. pool. Do not build 17 support frames using these dimensions, use templates, test, and make adjustments until you get it right before you build all 17 frames.
Look at the video for board diagram number.
Board 1 - 38 ¾
Board 2 - 44 ¾
Board 3 - 51”
Board 4 - 36 ½”
Board 5 - 36 ½”
Make sure you cut 1-2-& 3 at a 10-degree angle on both ends.
I hope this helps.
Thanks,
Norman

Is the lenght of the boards for the trapezoid the bottom lenght or the top lenght.

Ok so I’m wanting to build this same deck but my pool has 14 sides and my first board will be 59 inches how do I figure out the length of the outside parallel board? And the two that runs nearly perpendicular at 25.7 degrees? My brain has melted over this and there isn’t any help online or any apps that I could find.
I need additional information in order to answer your question: Is your pool round? What are the 14 sides? Why is the first board 59"? Let me know and I will try to help.

I used these measurements which worked out perfect for the first trapezoid. I also went ahead and built steps on the front side of the first one. However I went to build the second trapezoid and since I didn’t center the first one between the pool posts the second trapezoid is hitting the pole on the pool and not lining up with the first frame.
Should I move the frame back a few inches to allow the other trapezoid frame to miss the pole? Or should I center the first frame between the two poles?
With a 27ft round pool and a circumference of 84.82. How would I calculate the length of the bases of the trapezoid? I found a calculator for area but how do I plug in these numbers?
Since I have not built a 27 ft. round deck and tested the trapezoid size, I cannot give you measurements to use for your pool. Even the best calculations need to be tested first, before building. I suggest you build two trapezoid support frame templates out of 2 x 4’s. Make sure the support frames are square.
Lay the first trapezoid support frame to the left of your equipment panel and the second trapezoid support frame next to the first. Make sure the front of the support frames are at least 2 inches from your pool’s top rail.
Place a stake at each end of the trapezoid support frames. (wide ends) 3 Stakes
Move the two trapezoid support frame templates to the next position.
Place a stake at each end of the trapezoid support frames. Making sure you stay 2 inches from the pool’s top rail
Continue moving and staking the ends of the support frames until you reach the right side of your equipment panel. That should be 17 support frames to this point.
Make sure the trapezoid support frames are forming the correct circle around your pool as you go. Look at the stakes they should flow evenly around your pool.
If the trapezoid support frames are not following and even flow around your pool, you need to adjust the dimensions. If the frames are moving out from the pool you need to reduce the size of the trapezoid, if it is moving in before it gets all the way around to the equipment panel, increase the size of the trapezoid.
If the 17th frame forms a circle around your pool, measure the distance between the 17th support frame to the first support frame this will be support frame 18, which is custom built to fit over or under your skimmer, pump and return and connect to the first support frame.
This is only a suggestion on the size of trapezoid you should start with for a 27 ft. pool. Do not build 17 support frames using these dimensions, please build two templates first, then test, and make adjustments until you get it right before you build all 17 frames.
Look at the video for board diagram number
Board 1 - 41 ¾
Board 2 - 47 ¾

and making any adjustments necessary before building the 17 trapezoid frames.
Thanks,

The trapezoid calculations below will give you the approximate size trapezoid frame to build around your pool. You will have to test your calculations by building two templates out of 2x4s first. For additional help on how to layout the templates around your pool, please watch my Part 3 Pool Construction Video Update.
Here are the calculation steps:
Calculate the number of feet around the perimeter of the pool.
Example: A pool with a diameter of 21ft.
The formula for circumference is πd, meaning pi (~3.14) times the diameter of the pool. Plugging in 21 for d, you get π (21), which equals 65.973 ft.
The formula for adding a 3 ft. deck around the perimeter.
Adding a 3ft wide deck increases the pool’s perimeter to: Formula = 21+3+3 = 27 ft. in diameter.
Formula:
Area of the added 3ft deck minus the original pool perimeter =
π (27)2 Minus (21)2 = Area of the deck = 72 π ≈ 226.2 sq. ft.
2 2
The trapezoid frames will need to cover the square footage above.
The formula for the area of a trapezoid
= A = ½ (a + b) h
The area of a trapezoid is the space contained within its 4 sides. To find out the area of a trapezoid, you need to know the length of two parallel sides and the distance (height) between them. The sides should be measured in feet for square footage calculations.
where (A) is the area of a trapezoid, 'a' and 'b' are the bases (parallel sides), and 'h' is the height (the perpendicular distance between a and b)
For a 3ft deck, the parallel sides will be 36 ½”.
You have the known a and b.
Trapezoid height formula
The height of a trapezoid is the distance between its bases. And the bases are the parallel sides of the trapezoid.
There are two methods of calculating the height of a trapezoid, when the area is known and when the area is unknown.
The height of a trapezoid using the area
When calculating the height of a trapezoid using the area, you also need the measurement of the bases a and b
The formula method uses bases a and b along with the area of a trapezoid to determine its height:
h = (a+b) / 2A
Input:
a - 1st base of the trapezoid
b - 2nd Base of the trapezoid
A - Area of the trapezoid
The second formula for determining the height of the trapezoid using the non-parallel sides and angles:
h = c × sin ∠α
h = d × sin ∠δ
Input:
h-Height of the trapezoid
c - non-parallel leg c
d - non-parallel leg d and
sin - The sine function (the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle.
Building the Isosceles Trapezoid:
The sum of all the angles in a trapezoid is equal to 360°. The sum of the angles on the same side is equal to 180°.
To build a deck around a round pool you will need 18 trapezoids. The Base - Center and Top support boards must be cut at a 10-degree angle on both ends. The two parallel side-boards are straight cut and must be the same length.
You have 226.2 ft. to cover around the pool - determine the size trapezoid by calculating the area one trapezoid will cover.
I hope this helps
Thank you for watching my video

good video. Decking screws aren't meant for structural support, wouldn't galvanized structural exterior screws be better?
Yes, you certainly can use construction screws instead of deck screws to assemble the deck frame, however, they are not necessary for this type of structure and will increase the cost of the deck build. When you connect 18 trapezoid frames on top of the 4x4 posts in a complete circle, any force or pressure applied in any direction will be evenly distributed across all frames. This creates a very sturdy and stable deck frame surrounding the pool, as each trapezoid structure supports the others.
The screws in some deck frames are subjected to enormous pressure or force, like rectangular or semi-circle deck frames. Trapezoid designs whether it is a building or deck are very solid.
The pool deck featured in the video was built in 2007 and has withstood many pool parties, lots of foot traffic, two hurricanes, snow storms, Ice, and strong winds all without losing its strength and stability, even after 17 years only the top decking has been replaced.
Today, floating deck blocks, half-lap 4X4 posts, deck railing height, bolts, and other construction hardware are no longer approved in some states and counties. When this deck was built, it was considered a non-permanent structure, and all the above was approved.
I always tell anyone before they start building a deck to please consult with their local building inspector's office to determine the specific code requirements for their county and state.
I hope this helps
Thanks for watching my video!

We are putting this around a 15 foot pool, only 2/3 around and was planning on using the dimensions/cuts you listed in video but then I read comments and your replies so I am guessing that won’t work. I can figure out the diameter but have no clue how to determine the calculation for the trapezoid cuts. Can you help on calculation? Thank you.
I built a 15ft. round pool deck about 4 years ago, I still have the measurements I used to build the trapezoids. I am out of town and will return
On Thursday. I will locate my file and let you know the dimensions when I return.
Thanks,

Christina,
Below are the dimensions to build a 3-ft round deck around a 15 ft. pool.
These dimensions are accurate and will fit perfectly around your pool as I have already built a deck for a 15 ft. pool a few years ago.
Key points to remember:
Always start to the left of your equipment panel with the first trapezoid.
If you build a deck completely around the pool, the 18th trapezoid will be custom made to fit the remaining space from the right side of the equipment panel to connect to the first trapezoid.
• Make sure you have access to the connection points of your top rail so it can be removed without having to take apart
your deck.
• Follow the instructions in the video on how to set the blocks and position of the trapezoids on top of the 4X4 posts.
• Make sure you level each block and 4X4 posts as you go. The first trapezoid, blocks, and posts are critical in being
absolute level in all directions because from this trapezoid, all other frames will be matched.
• Check your local building codes and make sure you can use a floating foundation deck block system and use code
approve fasteners required for your area.

Board 1 - 29 ¾”
Board 2 - 35 ¾”

Our pool is 12x20 oval. I want to put a deck on only one of the curved ends. The distance between each pool support leg is 44 inches. Can you help with the dimensions for 4 trapezoids, if I want the deck to be 5 feet wide?
I don’t think you can use a trapezoid frame system on an oval pool. However, I haven’t looked at this type of pool for a trapezoid deck plan. I am out of town until Friday. When I get home I will take a look at my deck plans and see if it may be possible and let you know.
Thanks
Norman
I checked my files and do not have any trapezoid deck plans for an oval pool. However, you can build a partial deck at the end of your oval pool, but you can’t use the same build details and calculations shown in the video.
When building a partial circle, you have no support on each end of the deck frame. There is nothing stopping the deck frame from moving right or left.
Building a semi-circle or any size partial circle using trapezoid framing will require posts set in concrete, additional support framing, and construction screws used in the frame build.
Changing the width of the deck from 36” to 60” alters the entire structural dynamics of the trapezoid frame.
It would be easier and more cost-effective for you to build your deck using standard deck framing construction.
There are simple deck plans available for around $5.00 that would help you with your oval pool deck build. You can use these plans as they are, or modify the plans to fit the size you want to build.
I have used these plans in the past for round pools and they were very helpful in my deck construction.

For a 24' pool would you need a different trapezoid layout or just more of them?
You will need the same number of trapezoid frames but the dimensions will be different. A 24 ft pool has 6 additional feet of radius compared to an 18 ft pool. If you build using the 18 ft pool calculations, your trapezoid frame would turn short before you get all the around your pool.
Thanks,
Norman
@@NormanGooch how would you calculate for a 24' round pool?
Currently I have a deck, rectangle shape to the pool and only will need to wrap around about 3/4's of the remaining pool and tie in with the other side of the deck. Is there a formula?
Yes there is a formula and it's complicated. First you need to calculate the circumference. Write down the formula for finding the circumference of a pool using the diameter. The formula is simply this: C = πd. In this equation, "C" represents the circumference of the pool, and "d" represents its diameter. That is to say, you can find the circumference of a pool just by multiplying the diameter by pi. Plugging π into your calculator will give you its numerical value, which is a closer approximation of 3.14 or 22/7.[1] - 3.14 times 24. = 75.36 feet. this is the perimeter of a 24 ft round pool. The circumference of a pool is how far you would walk if you started at one point on the pool and then walked all the way around the pool until you got back to the starting point. You can't actually walk around the pool, measuring as you go. you must always calculate a pool's circumference based off its radius or its diameter. Next you have to determine the size of the trapezoid. Use an online calculator to figure the area of a trapezoid. The trapezoids will cover the 75.36 feet around the pool. It will take 18 to make a circle. You will build 17 trapezoid frames and the 18th will be custom built to fit between pump and skimmer set up.

What if I wanted to go 4’ on a 24’ round
Mike,
Please note that if you decide to increase the width from 3ft to 4ft, the build instructions shown in the video will not be applicable. Extending the width significantly alters the structure compared to a 3ft deck. It's important to consider that the use of floating deck blocks may not be allowed, requiring you to set the post in concrete, add additional support, use construction screws for the deck framing, attach railing with steel post supports (half-lap joints are not allowed), and include additional diagonal bracing. Furthermore, the trapezoid frame will need to be reinforced with 2 additional 4X4 posts on double center supports, with construction screws being a requirement for building the trapezoid frames. Before beginning the build process, I strongly advise checking with your local county building code department to obtain the deck construction specifications and ensure full compliance with the building code.
I hope this helps,
Thanks for watching my video!

Can you help me I am going to build this deck around a 30ft pool and I am need to figure up my material. Is there a formula? Asking because with all the angles I am just unsure.
Thanks
Melisa,
The material and hardware list are going to be based on your local county building code specifications for pool deck construction.
I can calculate the materials and hardware needed to be based on the same materials and hardware used in the video.
It will take me some time to estimate what you will need to build a 3ft deck for a 30 ft. pool. Before you purchase the lumber and hardware, make sure you check your local code requirements.
Will be back in touch with you soon.
Thanks for watching my video
Norman
Melisa,
I can only give you suggested measurements to use for your pool. The calculations need to be tested first, before building.
The circumference of a 30 ft. round pool is about 94’3” - Based on the number of square feet use the measurements below to build two trapezoid templates out of 2X4s.
The size trapezoid needed to cover the square feet around the pool:
Board 1 - 44 ¾
Board 2 - 50 ¾
Board 3 - 57”
Board 4 - 36 ½”
Board 5 - 36 ½”
Building the trapezoid Frame
Make sure you cut boards 1-2-& 3 at a 10-degree angle on both ends.
You will need: 2 - 2X6X10 boards to build one trapezoid frame.
From one 2X6X10 cut boards 2 - 3
From one 2X6X10 cut boards 1 - 4 - 5
Below is a suggested list of materials to build a 3ft deck for a 30ft pool.
36 - Concrete Deck Blocks
18 - 2X4X8
36 - 2X6X10
18 - 4X4X8
66 - 5/4-in X 6 X 12 Deck Boards
72 - Corner Brackets
72 - Joist Hangers
2 ½” Deck Screws - 5 Boxes
1 ½” Joist Nails - 3 Boxes
The above material list does not include the 18th trapezoid frame, deck railing, steps, or boards to enclose around the bottom of the deck.
Build Templates First!
Build two trapezoid templates out of 2X4’s. Layout the templates around your pool and test the fit, make any size adjustments needed, and test again.
It takes 18 trapezoids to complete a circle, the 18th trapezoid is custom built to fit the distance between the equipment panel and to connect to the 1st trapezoid frame.
Once your template layout is right, then you can build 17 trapezoid frames all the same size and 1 trapezoid frame custom-built to connect to the first frame. (Trapezoid #18).
For template layout help, View my Part 3 - Pool Deck Construction Update Video.
I hope this helps.

You used deck blocks on your pool design just wondering how stable they were because most of the time they say you don't use deck blocks on anything that's his height
Russ,
There are certain building code specifications for using a floating deck support system. Deck construction information can be found at your local county's building inspection department. It also depends on the type of deck structure that is built. Some counties do not allow a floating deck system.
The pool deck shown in the video is 58" high at its highest point. The deck is now 12 years old, but it is still stable and solid.
Thanks for watching my video,

If I make the length of 4 and 5 a foot longer at 48 1/2 will I need to adjust the lengths of the other boards
Henry,
You can't use the same build details shown in the video for the 36" deck build. Changing the width of the deck from 36” alters the entire structural dynamics of the deck and the trapezoid frame size.
The size deck you are wanting to build will require:
A new trapezoid size calculation.
Additional framing support.
The 4X4 post will have to be set in concrete footings.
You will have to use construction screws for framing.
You have to add additional 4X4 center support posts.
You will have to add additional bottom frame support.
Additional railing posts may also be required.
Check with your local county building code department and get the deck construction specifications to make sure you follow the building code before starting the build process.
I hope this helps,
Thanks,

Thank you for the quick response Norman, did the 3 foot width of the deck give you enough space around the pool?
@@henrymcwhorter1541
I have built several decks around pools and find that 3 ft is plenty of room to walk around the pool, easier to clean the pool, sitting benches allows up to 12 people to sit at the same time, room for toys, etc. The 3ft deck section around the pool is made for walking around the pool and for easy pool access. Attaching the 3ft round deck to a larger deck is where you build it big enough for tables, chairs, grills, etc.
Thanks,

Do you have a cut list for this video? With angles.
Sheila,
The construction specifications are for an 18-foot round pool. You can modify the dimensions and material list to fit your specific pool size.
Support Frames
You will start by building 17 support frames in the shape of a trapezoid. An 18ft round pool will take 18 support frames. The last frame will be cut-to-fit due to differences of pool sizes and construction procedures. For some pools, the filters will affect the framing of the deck. This is great location for the last custom support frame.
The diagram shows how to cut the boards to build the support frames.
• From a full 8ft. 2X6 support board cut A and B. Each end must be cut at a 10-degree angle.
• From a full 10ft. 2X6 support board cut C, D and E. Board C must be cut at a 10-degree angle. Boards 4 and 5 are the same size
These are the 5 board sizes needed to build one support frame.
Square” the Support Frame by adjusting the outside boards until the distance between opposite corners is equal.
After the Support Frame is “squared,” center and secure board # 2Install with 2 1/2” deck screws.
Secure with two additional 2 1/2” deck screws at each of the four corners of the Support Frame.
Install a galvanized metal corner bracket in each corner of the support frame and one 2X6 joist hanger each side of the center support board # 2

Around how much will this cost?
Juana,
The cost of materials to build the 3-ft. deck around the pool is around $1, 638.00. This does not include the cost of expanding the deck to your house, the railing, and enclosing around the deck. To add the railing the cost will be around $1,175. To enclose the bottom the cost will be around $890.00. (Total $3,703.00). The deck expansion (Connecting to the house ) shown in the video cost around, $1,543.00. The cost will vary as the price of lumber changes frequently. Also, the quality of the lumber you buy will be a factor in the cost. I only used high quality lumber for the pool deck project.

No the dimensions will not be the same. The trapezoid frames will begin to close in on your pool wall before you get all the way around to the right side of the equipment panel. You need to recalculate the square footage, pools circumference plus the additional 3ft deck width to determine the total square feet, then calculate the trapezoid size to cover the the square footage to fit a 21 ft pool. If you need help with calculations, let me know and I will help.

@@NormanGooch where can I look for the formula to figure that out?
I'm doing 3/4 around 21 foot pool 6 feet wide around 3/4 of pool
Marc,
Here are the steps:
Step 1
Calculate the number of feet around the perimeter of the pool.
Example: Pool diameter 21ft.
The formula for circumference is πd, meaning pi (~3.14) times the diameter of the pool. Plugging in 21 for d, you get π (21), which equals 65.973 ft.
Step 2
The formula for adding a 3ft deck around the perimeter
Adding a 3ft wide deck increases the pool’s perimeter to 21+3+3 = 27 ft in diameter.
Area of the added 3ft deck minus the original pool perimeter =
π (27)2 Minus (21)2 = Area of the deck = 72 π ≈ 226.2 sq ft
2 2
The trapezoid frame will need to cover the square footage above. (note this is for a 3ft deck)
Step 3
The formula for the area of a trapezoid
= A = ½ (a + b) h
The area of a trapezoid is the space contained within its 4 sides. To find out the area of a trapezoid, you need to know the length of two parallel sides and the distance (height) between them. The sides should be measured in feet (ft) for square footage calculations.
where (A) is the area of a trapezoid, 'a' and 'b' are the bases (parallel sides), and 'h' is the height (the perpendicular distance between a and b)
For a 3ft deck the parallel sides will be 36 ½”. You have the known a and b.
Step 4
Trapezoid height formula
The height of a trapezoid is the distance between its bases. And the bases are the parallel sides of the trapezoid.
There are two methods of calculating the height of a trapezoid, when the area is known and when the area is unknown.
The height of a trapezoid using the area
When calculating the height of a trapezoid using the area, you also need the measurement of the bases a and b
The formula method uses bases a and b along with the area of a trapezoid to determine its height:
h = (a+b) / 2A
Input:
a - 1st base of the trapezoid
b - 2nd Base of the trapezoid
A - Area of the trapezoid
The second formula for determining the height of the trapezoid using the non-parallel sides and angles:
h = c × sin ∠α
h = d × sin ∠δ
Input:
h-Height of the trapezoid
c - non-parallel leg c
d - non-parallel leg d and
sin - The sine function (the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle.
Step 5
Building the Isosceles Trapezoid:
The sum of all the angles in a trapezoid is equal to 360°. The sum of the angles on the same side is equal to 180°.
To build a deck around a round pool you will need 18 trapezoids. The Base - Center and Top support boards must be cut at a 10-degree angle on both ends. The two parallel side-boards are straight cut and must be the same length.
You have 226.2 ft to cover around the pool - determine the size trapezoid by calculating the area one trapezoid will cover.
I hope this helps,
Thanks,
Norman
Marc,
The type of deck you are planning on constructing cannot use the same build information shown in the video. The deck width and size cannot use a floating block support system.
Thanks,
Norman
How did you come up with that. Would you mind helping out with the measurements for a 30’ pool.
Michael,
You can't use the same build details shown in the video for a 30ft pool. First, check with your local building inspection department and get the material requirements and build specifications for deck construction in your county. They may not allow above-ground deck blocks (floating deck) for this size pool. Half-lap joints are no longer allowed for mounting 4X4 post railing supports, complete 4X4 posts will need to be bolted to the inside corners of the frame. There may be other or additional materials and build requirements needed to meet the code.
As for determining the size trapezoid frame for your pool, I have to do some additional calculations and will reply by the end of next week. (I am on vacation this week.)
Thanks for watching my videos,
Norman
Awesome! You are the man. Thank you so much.
I understand and I appreciate it. If you could by any chance get it for me beginning of the week I could pay you for your time.
I will try to get it to you if possible.
Thanks,
Norman
Thanks a bunch. I have a deck im trying to start for a customer.
Nice deck. Wish I could've seen the process and not just the progress.
I agree, I should have included video segments each step of the way. By the time I decided to put this on TH-cam, I already done most of the work and only had photos of various steps in the process.
Thanks for watching my video

I'm not sure what building codes you have in your neck of the woods but deck screws should not be used in the way that you have done as they are not designed to withstand shear loads.
Codes are different in each county and everyone has to check with their own inspection department for building structure approval. There is no load on the deck screws in the trapezoid deck structure. The load is all supported by the 4 x 4 posts. The trapezoids sit on top of the posts, the deck screws only hold the trapezoids in place as each are connected with 8 screws until a complete 360 degree circle is completed. Once a complete 360 degree circle is connected with a total of 18 trapezoids, the trapezoid deck structure is very solid and strong.
Thanks,
Norman
Apparently using your calculations for a 15', 18' and 24' you are basically adding 3" to boards 1,2,& 3 starting with 15'. At least that's what it looks like to me. So 21' diameter
board 1 (35 3/4), board 2 (41 3/4), and board 3 (48)
That is a starting point calculation to build a template. Depending on pump and return orientation and equipment panel size adjustments up or down may be necessary.
Thanks
Norman
You should be a professor
Thanks for watching my video!

A 3 inch deck? 🤯
Should be 3 foot deck.
Thanks
Norman
Your last name tho. 😆🤣😂😹😆🤣😂😹😆🤣😂😹😆🤣😂😹
Not sure what you are asking for?
That's an automatic code failure here. Here, pier blocks cannot be used on freestanding deck with a height of 20" or more in any 36" span. I cannot reiterate enough to viewers that you MUST consult your local codes and verify that your plans are code compliant.
I appreciate your response so other viewers can read and know they must check local building codes before constructing any size pool deck.
A decade ago, when this deck was built, a floating block system was approved up to 48” H if the structure was not permanent. Since this was an above-ground pool and the deck encircled the pool, the deck was considered a non-permanent structure.
