This is the best design I have seen for a dome because, as you clearly state, it maximizes the use of 4x8 sheets of plywood and eliminates the cost of hubs while providing enormous design convenience and flexibility. Really excellent work! Thanks for your willingness to share. It's wonderful to see innovation on display.
This is exactly the size I've been looking with the perfect height. Considering building a tiny home but I wanted the size of a yurt with a single story only. You have hit perfection.
Thank you for the time and effort you put into teaching people about this subject. I’ve learnt a lot and I’m looking forward to taking on this project.
I built this in my garden at a 0.57 scale factor so the footprint fit my garden. Had to raise it a little to make it so I could get in but it works perfectly. Great plans thank you for sharing Paul.
Holy shit this is awesome! I recently bought some plans from you but I'll be making this one first. Think I speak for everyone when I say thanks for making these opensource and FREE!! This is perfect for a modular tiny home on wheels I've been looking for!
This is the best design I have seen for any geodesic dome. I will build this one on a concrete platform so the door is square. The ability to combine multiple domes is amazing. Such a simple design with readily available materials.
I'm a draftsman an have been working through your tutorials Paul. Absolutely fantastic work on these, well done. I hope you do a tutorial on this, it looks like a lot of fun to model (and build). Wishing you all the best!
this by far seems the best. Paul thank you for simplifying! wathced tons of videos and hope to coordinate my plans to your site or here. this now is doable for any person of skill. best product to help a wondering human to find a humble home
Brilliant Paul I had been doing an octahedron breakdown for going into a corner and this dome does it. I am impressed and we will build one in Cullybackey N.I. Your are doing a fantastic service to the dome community Paul.
First, my respect to your kind heart for sharing your knowledge free. Also my appreciation for the brilliance of one-piece dome model. I saw your comment that wanger flanges could be expensive. You are a wonderful engineer but a bad salesman :)). God bless…
Excellent 👍. This is workable solution for many different applications that a homesteader may require. Easy fabricated in a shop during off times. Then assembled as needed. Thank you so much for your time and generosity.
Just discovered your channel and this video and am really impressed. This seems like some Buckminster Fuller-level innovation! Well done and thank you!
There isn't a cut list. A cut list would be awesome!!! I believe this is the most beautiful of all the domes to date! Thank you for sharing!!! It's a game changer.
Paul shares his plan including measurements plus hints and a how-to for free. and people like you still find something to complain about. use your head and go figue the cut list out for yourself. it is not rocket science.
Thank you Paul for your efforts and sharing your design. This is brilliant. Looking from above I notice that this design lends it self very well to stretching it into a tunnel.
Thank you for IDEAS THAT WORK, leading to other ideas that develop. I'm working on the ideas, and you implement your thoughts in a great sharing platform. Thank you for creating this site.
Thanks Paul, this is a wonderful design, with so many "features" in the result! Think I will try this with EMT, either 3/4 or 1 inch. Can even build in stages if rested into a corner, then flat wall, etc. Inspiring... thanks again.
I am looking for a dome plan for 2 persons, for a desert area, bolted to a slab, to serve as a hub for additional "add-on" daisy chain expansion. Glad I found your channel... was quick to subscribe! Thanks
Sure I can do that. But if you know what it is called, you can find one online. These type of domes are derived from catalan solids. This is for instance a disdyakis triacontahedron, which is a deltoidal hexecontahedron where the deltoids are split into two triangles. If you wikipedia them, you´ĺl see the similarity between the two. Here is a calculator for a deltoidal hexecontahedron: rechneronline.de/pi/deltoidal-hexecontahedron.php
You dont learn anything if everything is done for you. Any calculator can be used to find the chord factors , Strut Length / Radius equals Chord Factor. For a different size dome, Radius * Chord Factor equals Strut Length.
Great Job, very usefull for me ! Thank you so much for sharing and working for the community. I was looking for a good dome to build and this one is one of the best model I saw. I mean easier to construct for a good average size. Ideal for me. Thanks. I am still watching your channel with great attention and pleasure.
Maybe it looks like simple and from the math point and linking it is along with flat bottom. But there are actually 6 different pieces from engineering standpoint that has to be build, also triangles are bad gor any kind of openings like windows. I was thinking in the same direction but ultimately I came to a conclusion that less elements the better. My approach was mixing triangles penta and hexagon shapes to form modular structure. I ended up using only 5 elements with 3 od them not being prismatic (forming triangles) that are used for static load. Kudos for your work and sharing it. Really good work.
Paul you are amazing! Thank you endlessly for sharing your knowledge and plans with the world. We are a group of friends in Ontario and we want to collectively help each other build domes on each others properties. We love this plan due to the simplicity of only having the one size triangle, and the adaptable nature of this design, however we have a connection for free lumber of 3 feet in length (2x4 studs) we were hoping to utilize. Can this plan be modified, or you you have an alternate plan you would recommend us to use? Thank you kindly!!!
I really enjoy this dome style. The kite frame, with the single shape really simplifies it, plus the fact that the dome is dividable in 4 quadrants is really cool too! I'm planning to build a 4 season greenhouse dome and this might be my top choice. I plan to make a footing from ICF Blocks and insulate the north wall part way up. I'm curious if the dome size can be scaled up much without stressing the struts?
The 3 angles you might be looking for the kite triangle to make a jig are (it is not a right angle triangle): 86.97 degrees~87 59.13 degrees~59 33.90 degrees~34 It is derived from “Deltoidal hexecontahedron”
Was wondering about that, no 90 degree corner because when viewed in the plan view the corners appear to radiate out at 90 degrees. Paul mentioned that you could take a corner out or build onto a corner I just can’t see how that would work. I am wanting to build onto an interior corner could you or someone explain what I am not following.
@@fisheater844 probably it would work out since you have to fill the seem gaps with some a flexible material like silicon as a weather seal. So, I would not worry about it too much, it is though important to know the angles for building the dome as a whole. If you want to reduce the risk, build it on sketchup first and see how it would work. Good luck, and share results if possible
@@fisheater844 building on an inside corner you would only need a 1/4 of the dome, look at the plan view and divide it into 4 sections use 1 for an inside corner, 2 for a flat wall and 3 for an outside corner, 4 would be the stand alone dom
Definitely would like to have plans for this dome, I enjoyed the possibilities explored using Sketchup, and more importantly that this half-dome seats flat. That in itself simplifies a lot of issues.
Paul, this is a really cool plan, and I plan on building a scaled down version (with a knee wall) as a playhouse for my grandchildren. Thank you for sharing it. I have a question on the frame triangles though. I assumed from looking at the frame measurements diagram (on the 4th page) that the angle between the 1828mm side and the 1214mm side was a 90 degree angle. However, if I plug the three leg dimensions into a triangle calculator, I get that angle at 86.79 degrees and the other two angles at 34.56 degrees and 58.66 degrees. Is that correct? Thanks.
Fantastic Paul. I've been researching Geodesic domes for about 40 years. It's on my bucket list to build one. would love to talk to you about it if possible. Thank you.
This is awesome! Bang up job. Is there a Sketchup file available for scaling the dome? I'm looking to build an 8.5m half dome to cap a hoop house that I'm building around my camper and this is PERFECT! Thank you for sharing!
Amazing. My plan is for a 24 foot dome, and this is about 22, so I just need to put my thinking cap on and figure out the measurement changes to make that happen.
Thank you Paul for a great video and like Nicola Tesla you are a great humanitarian. I assume the framing is screwed together at various locations along each side. But it seem to me that the frame side that you show as 90 degrees would need a bevel also to create a circle dome? Have you actually built a dome from these plans? If plywood panels are used on top of the frame; I would assume the size of the panels would need to be expanded so all the corners fit together?
where is the sketchup Model? A friend and I are planning on scaling this up slightly and building it! How can you get the triangle dimentions, we want to form our own insulation inserts from Mycelium to fit in the triangle and overlap eachother like shingles. Coat them with liquid rubber on the outside and give it a sunken foundation
Haa! you are the best. Straight away an interesting build... Let me know how if this knocks up with the Joints you sell... I'm all in for the build, if so. thanks. I think Aircrete Harry and you should have a conversation, over a few beers.
Hi Paul, thanks for this bang up job, excellent work and very interesting. As you can split it into halves and quarters so easily, would this not make a great tunnel as well? I remember from your previous tunnel videos that was a difficulty with some of the 3V because they don't have a flat bottom and difficult to slice. Indeed this done would solve those problems the way I'm seeing it. I'll see if I can have a crack at it on Sketchup :) thanks for the plans! it is really appreciated!
Out of interest how rigid is this compared with a geodesic dome? I saw some stress testing somewhere in the past for a geodesic dome (may even have been this channel) so would be interesting to compare the strut stresses with this style of dome. Cheers.
@@Geo-Dome If you do get around to testing this, I'd be more interested in how well it copes with some struts missing. So eg this dome (minus struts for door) vs traditional dome (minus struts for door). It wouldn't surprise me if this dome is stronger once the doorway is factored in!
@@Geo-Dome I built a model in paper, seems to be quite floppy until you put the last bits in place and even then it doesn´t take a lot of side force. The shallow angle decagons have a tendency to invert.
I love this channel Paul and I want to build a dome . With any of my projects, I start with a model before taking on something major.The mirror triangle for your unity dome is brilliant however.... I want to build a diameter of 16 ft 5 in. instead of the suggested 22 ft .After scaling down the frame measurements to a factor of .082057---- for the model, I must have had the apex angle wrong because they do not fit . If there are 5 mirror panels with 10 triangles ,I presume that the angle at the top of each triangle should be 36 deg. ?(360 deg divided by 10) and the bottom should be 70 deg? since no angles are given on the plans. Thanks again for your devotion to domes.
I have downloaded your excellent plans. Thanks tremendously. Since each side is a mirror image, could a one or two meter extension be added at the seven nodes to elongate the design? Thanks in advance for your reply. I really enjoy your videos.
Firstly, I want to thank you! And I have a question. What is dimensions of wood material? Not length, but width. Ex. 5x5 cm, or 7x7 cm...? I think is need to have some width for this dimension...
Rule of thumb for timber domes is the depth of timber should not be less than 1/24th of the strut length. For a 6ft strut that would be 3". The timber width should allow for minimal deflection, rip the struts from stock that will provide 2" of timber width when the two panel edges are screwed together. The strength will be equivalent to using 6ft and 4ft *3x2`s (*finished size) to build the dome.
@@JohnGuest45 Thanks for the guideline. So if the longest strut in this build is 7', the finished size of the timber would need to be 1" w x 3.5"d x 7' long?
Interesting structure! Thanks! It seems that it would be possible to build the dome using a combination of four corner kites and the two triangles only where you want the dome to meet the ground or a wall. Each kite is flat, the curve of the dome is created only where kites or single triangles meet. Would it weaken the dome a lot to take out the two middle sticks in each kite?
Paul thank you again for for the content and hard work, i have a question about making frames, can we use a regular 2x4 to build the frames or does it need to be a narrower ripped board? Thank you again!!!
I just found this, and love the design and what seems as the easiest dome construct I found to date. I have one question... This is for a 6,7m dome, covered in plywood sheets Would it be possible/advisable for me to add a percentage to the material thickness/lengths to enlarge the dome to the size I would like ? (I would like to make a dome with this system of diameter 10m or so
Hi Paul, Thanks for your time and for sharing so nice ideas with us. Just a little stupid question. I first imagined all triangles were right-angled triangles, but then I went on the slide concerning the frame measurements and 1214, 1828 and 2137 do not fit with Pythagore! May be I misunderstood or perhaps these dimensions are not in the same plane.
I am building a dome but covering it with polyethylene and growing ivy over it. No maintenance and the ivy will eventually become structural. I am doing the same thing in Portugal with cork oaks to produce a house that requires no heating or cooling at all.
I don't recommend 2x4 as it's the wrong ratio, just a bit wide for getting screws into. You can use 3x2 cut with the bevel angle down the centre and get two pieces, or 2x2 same cut down the centre.
@@Geo-Dome I can only get 3x2 in 8' lengths. For these struts could I rip a 2x6 to 2x3 (actual size 1 1/2" x 2 3/4") then cut the bevel down the center of the 1 1/2" width? Would a 2 3/4" depth be strong enough for the 7' length struts? Thanks for all you do to make the world less square!
Can this be built from electrical conduit? The each conduit strut serves as a side to two panels. What is the biggest dome that can be made with 10 ft pieces of conduit? Each 10 ft piece of conduit usually gives you two struts of varying length. For a standard dome: Largest Dome made from 10’ stock: length of strut ( number of struts) = length of conduit piece; 64.198”(20) + 47.990”(30) = 115.188”; 61.350” (80) + 55.644” (35) = 119.994”. A 10 ft conduit is obviously 120” I got a bunch of conduit from an electrician who was retiring. I plan to sheath it in used boat heat shrink plastic and maybe spray foam the inside or outside. If you spray foam the outside, you can cover the foam with more plastic, and maybe dismantle the dome framework inside! I don’t know how strong that would be, though. 1.5” Added for strut ends
Absolutely Awesome again Paul, May I ask, if I was to reduced the 1214 struts to 1200 as most uk sized timber comes in 2.4, how would I re-dimension the other sides to at lease get 2 x cuts from a length. As it would need 3 sticks per triangle as it stands for now. Many thanks in advance Sir
Paul, I have a question about the angles in the triangles. Based on the 1214/1828/2137 lengths, instead of 30°/60°/90°, they're ~34.5°/~58.5°/~87° (much more complicated to cut and inefficient to cover with right-angled plywood, fabric, etc). Was this for reasons intentional, was it simply by chance, or is it an unintended rounding error? If we can use 30°/60°/90°, it would be a lot easier to fabricate (fewer cuts) and cheaper to source (as we could make more optimal utilization of right-angle substrate sources). We'd probably have to reset the bevel angles, however - but maybe that would not be a hardship. Your thoughts? Thank you!
Ah yes a very interesting question, if we changed the angles to 30°/60°/90° we could only produce a flat tiled surface. The small difference in face angle makes it possible to tile a sphere. If I force the 90° angle the others have to be 31.7° and 58.3° respectively and form the faces of a Rhombic Triacontahedron divided in four. Hope this helps.
It would be nice to have Imperial measurements but not necessarily needed. I wonder what it would take to make this into a tunnel type structure? Being roughly 20 feet in diameter it's not enough room to build a 17 foot kayak and get around it. Adding 6 to 8 feet in the middle would be sweet.
You can actually do this build a hoop house with two ends ending in a half dome. If you want an easier tunnel, look at the icosahedron. That middle part will just repeat endlessly giving you a tunnel.
hi Paul, I have recently found your channel, and it's awesome, thank you so much :-) may i ask a silly question; how do you secure the wooden base to a concrete foundation and waterproof it?
I sure would like to get the imperial measurements and would like to know if this design is structurally sound as I have read with more complex designs.? and thanks for Your knowledge, In san diego Calif
A very interesting plan, Paul. Where would you suggest that I place the windows, if I want them to open. I plan to make one or maybe two (one 3 meters in diameter and one 5 meters in diameter) greeenhouse models with solid polycarbonate, both of them with a higher base, than shown.

Haa! you are the best. Straight away an interesting build... Let me know how if this knocks up with the Joints you sell... I'm all in for the build, if so. thanks.
I think Aircrete Harry and you should have a conversation, over a few beers.
This one is really beautiful
Hi Paul, thanks for this bang up job, excellent work and very interesting. As you can split it into halves and quarters so easily, would this not make a great tunnel as well? I remember from your previous tunnel videos that was a difficulty with some of the 3V because they don't have a flat bottom and difficult to slice. Indeed this done would solve those problems the way I'm seeing it. I'll see if I can have a crack at it on Sketchup :) thanks for the plans! it is really appreciated!
Thanks Paul. Great information. Useful building.
Out of interest how rigid is this compared with a geodesic dome? I saw some stress testing somewhere in the past for a geodesic dome (may even have been this channel) so would be interesting to compare the strut stresses with this style of dome. Cheers.
I would say more rigid, it has all great circles which will guid forces down to the ground. I would need to do some tests though.
@@Geo-Dome If you do get around to testing this, I'd be more interested in how well it copes with some struts missing. So eg this dome (minus struts for door) vs traditional dome (minus struts for door). It wouldn't surprise me if this dome is stronger once the doorway is factored in!
@@Geo-Dome I built a model in paper, seems to be quite floppy until you put the last bits in place and even then it doesn´t take a lot of side force. The shallow angle decagons have a tendency to invert.
I love this channel Paul and I want to build a dome . With any of my projects, I start with a model before taking on something major.The mirror triangle for your unity dome is brilliant however.... I want to build a diameter of 16 ft 5 in. instead of the suggested 22 ft .After scaling down the frame measurements to a factor of .082057---- for the model, I must have had the apex angle wrong because they do not fit . If there are 5 mirror panels with 10 triangles ,I presume that the angle at the top of each triangle should be 36 deg. ?(360 deg divided by 10) and the bottom should be 70 deg? since no angles are given on the plans. Thanks again for your devotion to domes.
I have downloaded your excellent plans. Thanks tremendously. Since each side is a mirror image, could a one or two meter extension be added at the seven nodes to elongate the design? Thanks in advance for your reply. I really enjoy your videos.
Firstly, I want to thank you! And I have a question. What is dimensions of wood material? Not length, but width. Ex. 5x5 cm, or 7x7 cm...? I think is need to have some width for this dimension...
Rule of thumb for timber domes is the depth of timber should not be less than 1/24th of the strut length. For a 6ft strut that would be 3". The timber width should allow for minimal deflection, rip the struts from stock that will provide 2" of timber width when the two panel edges are screwed together. The strength will be equivalent to using 6ft and 4ft *3x2`s (*finished size) to build the dome.
8x4 = roughly 10x20cm, then cut it ( as shown from 3rd minute on )
... Well, to my understanding anyway.
Thank You, Paul !!!
@@dariostarsky8124
8x4 is 8ft x 4ft , in some places its only 1200mm x 2400mm
I would be interested in that also ! Can t see the answers ... all in private. Thanks for this great dome pre work!
@@JohnGuest45 Thanks for the guideline. So if the longest strut in this build is 7', the finished size of the timber would need to be 1" w x 3.5"d x 7' long?
Brilliant!! Thank you for the free plans.
I wonder if this will transform into a tunnel as neat as the dome itself. I really do like the way the triangles look in this dome.
Interesting structure! Thanks! It seems that it would be possible to build the dome using a combination of four corner kites and the two triangles only where you want the dome to meet the ground or a wall. Each kite is flat, the curve of the dome is created only where kites or single triangles meet. Would it weaken the dome a lot to take out the two middle sticks in each kite?
What are the angles of frame triangle? by given measurements it doesn't look to be 90 degree triangle. Thanks for response!
Paul thank you again for for the content and hard work, i have a question about making frames, can we use a regular 2x4 to build the frames or does it need to be a narrower ripped board? Thank you again!!!
I just found this, and love the design and what seems as the easiest dome construct I found to date.
I have one question...
This is for a 6,7m dome, covered in plywood sheets
Would it be possible/advisable for me to add a percentage to the material thickness/lengths to enlarge the dome to the size I would like ?
(I would like to make a dome with this system of diameter 10m or so
Hi Paul, Thanks for your time and for sharing so nice ideas with us. Just a little stupid question. I first imagined all triangles were right-angled triangles, but then I went on the slide concerning the frame measurements and 1214, 1828 and 2137 do not fit with Pythagore! May be I misunderstood or perhaps these dimensions are not in the same plane.
I am building a dome but covering it with polyethylene and growing ivy over it. No maintenance and the ivy will eventually become structural. I am doing the same thing in Portugal with cork oaks to produce a house that requires no heating or cooling at all.
Are you planning on building one of those any time, Paul? Cheers for everything you do!!
This is AWESOME, Paul... thank you for sharing! Quick question... would you recommend 2x4 for struts or would 2x2 be ok?
I don't recommend 2x4 as it's the wrong ratio, just a bit wide for getting screws into. You can use 3x2 cut with the bevel angle down the centre and get two pieces, or 2x2 same cut down the centre.
@@Geo-Dome That's a big help, Paul! Looking forward to making a model first... beautiful and simple design...
@@Geo-Dome I can only get 3x2 in 8' lengths. For these struts could I rip a 2x6 to 2x3 (actual size 1 1/2" x 2 3/4") then cut the bevel down the center of the 1 1/2" width? Would a 2 3/4" depth be strong enough for the 7' length struts? Thanks for all you do to make the world less square!
Can this be built from electrical conduit? The each conduit strut serves as a side to two panels. What is the biggest dome that can be made with 10 ft pieces of conduit? Each 10 ft piece of conduit usually gives you two struts of varying length.
For a standard dome: Largest Dome made from 10’ stock: length of strut ( number of struts) = length of conduit piece; 64.198”(20) + 47.990”(30) = 115.188”; 61.350” (80) + 55.644” (35) = 119.994”. A 10 ft conduit is obviously 120”
I got a bunch of conduit from an electrician who was retiring. I plan to sheath it in used boat heat shrink plastic and maybe spray foam the inside or outside. If you spray foam the outside, you can cover the foam with more plastic, and maybe dismantle the dome framework inside! I don’t know how strong that would be, though.
1.5” Added for strut ends
thank you for sharing, any chances of getting a set of plan with imperial measurements?
How do I cut this down to have a footprint no bigger than 108 sq ft. This way I can avoid building permits.
Any updates to this? More details? looks great!
This is what the ibternet was made for! Thank you!
Can this be built with wanger flanges?
Yes the geometry is no problem but I think it would be expensive, you would need maybe 300 or so, Let me just check and get back to you...
Absolutely Awesome again Paul, May I ask, if I was to reduced the 1214 struts to 1200 as most uk sized timber comes in 2.4, how would I re-dimension the other sides to at lease get 2 x cuts from a length. As it would need 3 sticks per triangle as it stands for now.
Many thanks in advance Sir
Paul, I have a question about the angles in the triangles. Based on the 1214/1828/2137 lengths, instead of 30°/60°/90°, they're ~34.5°/~58.5°/~87° (much more complicated to cut and inefficient to cover with right-angled plywood, fabric, etc).
Was this for reasons intentional, was it simply by chance, or is it an unintended rounding error?
If we can use 30°/60°/90°, it would be a lot easier to fabricate (fewer cuts) and cheaper to source (as we could make more optimal utilization of right-angle substrate sources). We'd probably have to reset the bevel angles, however - but maybe that would not be a hardship.
Your thoughts?
Thank you!
Ah yes a very interesting question, if we changed the angles to 30°/60°/90° we could only produce a flat tiled surface. The small difference in face angle makes it possible to tile a sphere. If I force the 90° angle the others have to be 31.7° and 58.3° respectively and form the faces of a Rhombic Triacontahedron divided in four. Hope this helps.
It would be nice to have Imperial measurements but not necessarily needed.
I wonder what it would take to make this into a tunnel type structure? Being roughly 20 feet in diameter it's not enough room to build a 17 foot kayak and get around it. Adding 6 to 8 feet in the middle would be sweet.
You can actually do this build a hoop house with two ends ending in a half dome. If you want an easier tunnel, look at the icosahedron. That middle part will just repeat endlessly giving you a tunnel.
Would scaling back the frames change the angles? Assuming all the lengths are scaled back in an equal ratio ie. 20%?
Good design! Thank you!
Instead of taking those 2 panels out and putting in that door frame, could you just add hinges to those panels and make them into a door?
hi Paul, I have recently found your channel, and it's awesome, thank you so much :-)
may i ask a silly question; how do you secure the wooden base to a concrete foundation and waterproof it?
Thank you for share,AMAIZING
I sure would like to get the imperial measurements and would like to know if this design is structurally sound as I have read with more complex designs.? and thanks for Your knowledge, In san diego Calif
A very interesting plan, Paul. Where would you suggest that I place the windows, if I want them to open. I plan to make one or maybe two (one 3 meters in diameter and one 5 meters in diameter) greeenhouse models with solid polycarbonate, both of them with a higher base, than shown.
By the way, does your UA-cam name (pauly1060) give away, that you were born in October 1960? If, then happy 60 years anniversary very soon.
thats awesome thanks mate! from NZ
