- An overview of a large 12m diameter dome I built recently, there are no metal hubs in this dome, no timber is larger than 2x2 or longer than 6' 6". There is no glue just several hundred wood screws holding it together

Stunning! The construction looks impeccable.
The drone effect...Spectacular Paul, I bought your plan a while ago, someday I will catch up on my other projects and built my own dome
Well done, Paul. Congratulations
Thank you for all you work on and greet share! You’re my source when I’m ready to build! Thank you!!!
Wow! Awesome design!
That is fantastic Paul. I am nearing completion of my 4.5 metre dome. All the wood is cut and milled for the last of the triangles and we should start covering with plastic this weekend. I have always harboured a dream of building a 15 metre dome but thought it would be outside of my capabilities but having watched your videos on building the 12 metre dome I can see that it is indeed very possible for me to build a big dome. I will be buying a set of plans very soon. I will send you some pictures of the dome when it is done.
Beautiful!
Awesome work!
the use of screws sounds like a feature - this may work here however generally properly designed glue connections are superior in terms of e.g. longevity. Obviously depending on the usecase and the construction. Totally impressive nevertheless. Thumbs up.
Very good job amazing achèvement. Just i would like to know if all triangle had te same size please ?. Thank you
wonderful content!
Your work inspires.Now can buy a plan?
Hello from Russia.
In my opinion, Good Karma, the best type of compound Connector without beams. And you are no "cold bridges", what is important in our climate zone.
Amazing!
beautiful
Awesome domes Paul. How do i figure out what the angle of the moldings are supposed to be? Is it dependent on the frequency? 360 degrees divided by number of base segments around the full dome base times .5 ? am looking to make a small 3 season room off my small livingroom with only an entrance from the living room..1/4 Sphere.
sweet, love the entrance.
Cool music, enjoyed the video...
paul blarting like a boss
Thanks for the tip Paul. 3x3 is not common here and I have about 300 2x4 laying around...lol... I'll find a way... And I'm looking into using a layer of ETFE or double layered polycarbonate.
Looks great!
Just a couple of questions:
- how tall is the dome (ie what fraction of a sphere it is)? It looks wider than taller
- do you know roughly the max. load the nodes can take?
Hi Paul, and thanks again for the awesome video. I've read alot of case studies suggesting the walls of a dome should have a min thickness of 4.2% of the diameter. Question, when you build your domes, do you always keep to such rule, or does it depend on the material used?
That is truly amazing, and it looks like very exacting precision work since you are not using any metal huge or connectors. 6'6" is still pretty large, especially when it is all connected together! Great job! I cannot believe you, or someone, is walking on the top of that! Scary!
I am trying to get up to speed on constructing domes. What is a good resources to use. My end idea is to build a nature house, that is to cover a regular house, small one of course, with a transparent dome to resist the cold and rainy weather. Maybe snow, as I see people are concerned about snow loads. It would be good to know how to cover the dome as well.
One idea I had was to find a way to scale the dome in the vertical direction, so that it is higher, and most of the walls are steeper
I would start with one of pauls plans to get the idea of it.
Hello Paul. Are your dome plans simple enough for a newby to domes to build? I’m super eager to get start and am not easily discouraged. Saved up money and purchased some land about a month ago and want to build a 13m GD62 on it. I will.
frecuencia?? es un v5 ??
The plastic appears to be a continuous membrane across the triangular sections. Is it? Or does each triangle have its own separate sheet? Beautiful dome and inspirational work!
Wish he would give an answer on that .... it's been a year
It's not. He has a video somewhere of him making it. He puts sections together and wraps those, Screws wrapped sections together and uses polythene tape to "flash" the joints.
You built it yourself?
2 comments: First of all, I wouldn't use Polyethylene (or whatever type of plastic sheeting you use) to cover domes. I have been covering the windows of my porch with this stuff, and the wind knocks it out in about 2 years. I mean, it looks nice at first, but the stuff doesn't last. Secondly, I always assumed that if you start getting into higher frequency domes, you risk having sections pop in because the dihedral angles get so flat combined with the unavoidable inaccuracies and the lack of rigidity of the struts. I always thought for higher frequency domes you would have to go to a double layer, like Fuller's Montreal Expo Biosphere. I do see that this dome you are showing here is 8v and you are shown walking up it. Well, that's very impressive!
I use horticultural polythene, I'm getting over ten years from a cover: czcams.com/video/3gthC16NvlQ/video.html
Oh the 40ft dome is actually a 4v with internal studding to each triangle frame, making it look like an 8v (well spotted by the way) all the angles are the same as a 4v so no risk of inversions, this article explains: geo-dome.co.uk/article.asp?uname=sudo_domes I would agree, bigger would need a double layer.
Here in Quebec we have important snow loads. Do you think 2''x 2'' are strong enough or should I use 2'' x 4'' that are standard here?
+Michel Loisel 2x2 would be strong enough if the lengths are short or you build a double layer, to get an idea about snow loads you can use this tool: geo-dome.co.uk/snowload_tool.asp enter radius in meters and depth of snow in cm to get an idea about total weight. The only thing I would say about 2x4 timber is as you go down the dome from top to bottom each board rotates so the bottom ones are on there side. Better to use 3x3 if you can get it in my opinion.
ok time for multiple domes on top of each other you should grow a bamboo forest in that!
Hello. Thanks for your videos. Whether you use sealant, between triangles?
Andrey Andrey No i don't use sealant because it won't stick to the polythene, I use polythene repair tape on the joints but make sure to use s credit card or similar to remove all air between the tape and polythene.
Thanks, I am glad you mentioned what the skin is made of ... but how on Earth did you get that around and so tight around the whole dome ... it's amazing?
Look absolutely amazing. Is it in your garden? What will you use it for?
forfengeligfaen No it's not in my garden ( I would like one though) it was for a local customer who grows banana plants and other larger tropical plants.
Please tell me what material you use to cover the domes? Polyethylene or polyvinyl chloride? The thickness or density ... Thank you.
Whatever it is, it is pretty strong, that dude is up there walking on the top of it. But if it breaks, I'd hate to have to repair it. That thing is huge!
Absolutely beautiful !
What frequency, method and class is it ?
mike wazowski It's my own geometry close to a 4v icosa details here: geo-dome.co.uk/article.asp?uname=new4v_design and a bit about the subdivision method here: geo-dome.co.uk/article.asp?uname=Regular_subdivision
Paul Roinson Thanks Paul ! I'll check them out !
Thanks.
what is the frequency?
Awsome! I am planning to build 12m dome with good carma type
This is awesome. What purpose will this dome have? Greenhouse, or just to show off? (which btw works)
***** It's a bit of both, the customer has large banana plants and other tropical plants that need to overwinter undercover, but it's also a reading room and party structure.
what plastic was used? polycarbonate? what thickness? what did it cost?
This is horticultural polythene, same as on a poly-tunnel. Cost would be maybe £300 for the whole dome, £25 for repair tape on the joints.
When you say 2x2 do you really mean 1.5" x 1.5"? You rip a 2x3 in half or a 2x4 in half?
I've been working my way through all Paul's video's. He does explain in one of them that he usually uses a standard 2x2, which is approximately 1.5" in North America, but is a little larger in the UK (still smaller than 2"). Then he rips them down the centre at a specific angle. I have also seen him use a 2x3 ripped the same way for some domes.
Brilliant! That's the best looking geodesic dome I've ever seen. Mind if I ask the cost?
Ray OfMinneapolis Materials cost about £2000 and it took me two months to make it, pretty cheap for the size of it I think.
+Paul Roinson absolutely amazing build
What is the cover material?
UPGardenr Cover material is horticultural polythene stretched and stapled over the timber frame.
How long did you build it?
MARK M It took 2 months to build in my workshop and 9 hours to erect it on site with four people.
You build some very nice geodesic domes. Why don't you use any wood glue?
It makes pulling a panel out for repairs a serious pain in the ass.
