In this video I show you step by step how to build a geodesic dome using the most beautiful, least expensive method that exists.
I have been designing and building wooden geodesic domes for years. Due to popular demand I have come out with plans for my most popular designs, and will be adding more. The techniques I present in this document will allow a hobbyist or professional of any skill level to build an incredibly unique a beautiful geodesic dome.
Included in the plans are all the specifications and measurements needed to complete the project, a list of needed tools, a materials list, and a thorough 15-page step-by-step walkthrough of how to build the dome of your dreams!
Quick overview of time, materials and tools:
--Tools needed: Beyond a table saw, miter saw and screw gun, only very basic tools are required.
--Material cost: Depending on where you source materials the 15' and 20' Dome will cost around $500-$1000 in materials. 10' Dome around $300-$600
--Time to build: This varies wildly between people. Give yourself a few weeks to complete if building in your spare time. But something like the 10' dome can be done in 2 or 3 days once you get the hang of the process.
These ideas are backed up by years of experience and many happy customers. After being asked online endlessly for tutorials and details, I have finally given it the time, so that the magic of dome building with this simple and beautiful method can be shared far and wide. IF you run into any trouble, don't hesitate to reach out.
These structures can be used for green houses, sauna, cabin, tiny house, glamping, off grid, trellis, garden art, etc!

As a septuagenarian I find myself watching your video thinking about the 60’s and 70’s when B.F. was in high form and popularizing the geodesic dome. Embraced by the back to the earth movement and other self reliant minded individuals many domes were built. Most not very well constructed, but some absolutely beautifully appointed finished structures. I am pleased that you posted this video and to witness someone of your generation carrying on the tradition and offering your knowledge for anyone willing to take the challenge. This struck me in a very positive way.

[@trilliumdomes]

Wow! I'm so happy you feel that way. Thanks for sharing those kind words :) We will do our best to continue the legacy!

[@Davett53]

Just a year shy of being 70,....I was in high school when those great books came out. Dome Books 1 & 2,.... ( and The Whole Earth Catalogs), we experimented with them in high school and the following years while I was in college. I was into the whole Ecology movement, too. Predating all the recycling going on these days,..it was a shame it took so long to be adopted. In high school we built "test domes" out of alternative materials, like heavy duty cardboard tubes, and card board sheet goods, PVC pipe, and wood. Buckminster Fuller used lecture on college campuses,.....I've see serval films on him, predating videos. He was a genius and wasn't appreciated, and mocked and called a con-man. A view I do not hold. After college in 1975,...my friends bought cheap land in Southern Ohio, and some learned to build cabins, like the earliest Pioneers,....others built Geodesic Domes. One friend built a dome and raised his family in it,...it was a constant learning experience, as there were no kits, or companies manufacturing, parts, connectors or juncture hardware. That has changed considerably since then.

[@anim8torfiddler871]

I'm just at the first FRAME of this video... Absolutely Thunderstruck am I. This is gorgeous. Really makes me appreciate the excellent work of the man cutting all the struts. You have to be able to work methodically and love the process. In both music and animation, I finally learned that there are some things that will work ONLY if you're able to apply Disciplined Precision, and other areas that reward creative excursions from that discipline... within LIMITS. I've never worked with an animator or a musician that was able to improvise, without having invested countless hours in rigorous exploration of the craft. And I don't mean just doing mind-melting scales, but at least taking the time to really master certain mechanical or _"structural"_ fundamentals. The worst that could happen with fiddling was having a string break and smack your face. With animation -- a paper cut. I took welding & metal fabrication classes, and saw some *turble* injuries from people "screwing around," or just losing focus.

This video provides a thorough description of the exact steps that need to be taken to construct a geodesic dome! I love the level of detail that you have provided!

[@gaminawulfsdottir3253]

I disagree. This video gives a good explanation of how to make the cuts (and on an assembly-line basis), but if you don't already know what you're building, you are quickly completely lost in trying to follow. The video starts with the assumption that you already know what size and shape to make the triangles. It's not a step-by-step of building a dome; it's about how to make the beveled and angled cuts -- assuming you already know what cuts you need to make and why they need to be beveled and angled.

[@andrewbagguley8289]

I have an interest in geodesic domes, and to see the care and attention paid here, not just to the design and build, but to the imparting of information to us is wonderful.

Years and years ago, I built an 12' foot diameter elliptical greenhouse dome from the strut tables in "Domebook II". It cost me a six-pack and a few hours of time with a math-oriented friend that had a HP calculator, I used old 2x2 tomato stakes and PVC hubs. The finished structure was beautiful but the doorway was impractical due to the strut design. Looking at your elegant hub-less design and construction jig brings back a lot of good memories. Thanks for your expertise and sharing! John T - ex Peaceful Glen Organics.

[@KingTesticus]

Nicely done. My first dome was a 4-frequency that was 1 meter in dia. It came out so good I decided to duplicate it at 6 meters diameter. I made it so it sets up & breaks down reasonably quickly. One person can set it up in under 2 hours, and break down is very fast, like 40 minutes. Since then I have made several domes, but the easiest one to set up & transport is a 2-frequency 4-meter dome made from 1-½" pvc electrical conduit. I throw a tarp over it, lash a hammock to a couple corners, and it's an awesome camping jobbie.

[@justgivemethetruth]

So true, I've been interesting in domes since the 1970's as a kid, and every time I've looked into it, they seem to make it as complicated and full of jargon as they possibly can. From what I've been able to determine, there is the basic form of the dodecahedron which is subdivided and modified to expand it and make it more spherical. But all the angles are very confusing, but not impossible to understand, and should be able to be reduced to a formula, or even a computer program. I applaud your work and your attitude! You look a lot like Eddie Van Halen.

@@paulbrouyere1735 great question. It’s very difficult to make functional doors that don’t hang limb and level. When doing that, if you were to do a non square door, you may only be able to get one hinge on it, which is not ideal.

I am planning to make a winter garden, the frames of which I cover with polycarbonate. I've seen you use double-sided insulation tape when attaching polycarbonate to frames. But while you were assembling the dome, I couldn't understand what you used for waterproofing between the frames. I saw in the video that you only connect it with screws, but I think this will not be enough for waterproofing. Thanks again for your interest and sharing =)

I am 66, so I recall hearing about domes in the 70s and even seeing a couple of them in rural VA. One dedicated eccentric was building a spherical boat in his backyard. It consisted of two domes connected to form a geodesic ball. He had a theory that there would be a major flood which would reach the mountains south of Charlottesville, where he lived. The boat ball would be his family's survival ark. Being about 19 at the time, I didn't know what to make of it all. His family seemed to be along for the ride (float), though I now realize they were humoring the survivor of a breakdown. I don't know whether the boat was ever completed.

Terrific job. Good for you. I have the orginal Domebook from 1970. I made my first dome model in 4th grade in 1960. I never built a large dome and still fantasize of doing it. My house is kind of junky, structurally, and an attached truncated dome would be really cool. Figuring the attachment geometry seems to be the hardest problem.

Well I think you know what I’m going to say… you should go for it! If you want help designing something like that, let me know

[@drlangattx3dotnet]

@@trilliumdomes Thanks for the encouragement. One trouble I have is too many dreams. I got boat dreams too. THe intersection of the dome and existing structure is the most interesting/difficult technical detail. I might build a cardboard scale model for the fun of it. Where is your home? Again, since I have been looking at domes, and Fuller ideas for most of my life, it is very cool to see someone like you taking things into your own hands. Have you seen Geoship?

Very good stuff brother!

Have you tried glass panels set into rebates in the struts? They could be set in clear silicone sealant. Use trim strips over the joint after joining the panels. Also set on silicone.

When marking your table saw surface, they make a product for scribing layouts on steel. It's called 'blue marking dye'. They have it in spray form. It allows you to mark a surface easily without having scratches in the surface. AND, it cleans up easily with acetone or lacquer thinner. Cheers!

Hey thanks for the tip!

The scratching on the tablesaw killed me. It's one of my go-to flat references in my shop.

[@andr0373]

@@noiamhippyman I thought he scratched a mark in the tablesaw, but I looked again and it was just pencil. The saw top did have some pretty good scratches in it, but I imagine that is from cutting thousands of struts. I think you'll need a really good table saw and skills for this, but the nice part is this project is cheap practice.

Spotted the machinist!

[@SenselessUsername]

@@umaikakudo hm... the machinist would have called it by name so you can easily buy it, "layout fluid". And I'm not a machinist, I just watched Adam Savage geek out about it, in kzbin.info/www/bejne/pGbPknqfaKyCba8

Just subbed definitely interested in this thanks for what you do.

Amazing! 🎉🎉 Thank you 😊

[@gibifikirler8651]

Thank you for all that knowledge. That’s value for me. 🙏

[@rodmills4071]

When I saw you pull out the hand saw, i said hang on isn't that a compound mitre saw. Nice that you showed how to do the cuts by hand. Not every one has a compound saw.🤔😀😎🇦🇺👌

Sir, best timing ever...You have a great product there...i am very into it...been juggling for the last year an a half on what type of green house...had the dome option in my back pocket and also sent plans to municipality to see what they would say, they were slow this year to respond, gave me a chance to discover a better dome...I am trying to figure out the rough cost, i know i should buy the plans but just still trying because of the price of wood now...but i have to admit...i will push really hard to get your concept accepted so i can build one...and of course, i will buy the plans...i want it to be perfect and want the project to go as smooth as possible..Thank you again..great video and amazing idea...

[@trilliumdomes]

Price of wood is falling rapidly and down to a very reasonable price. As little as $500 in lumber for a 20' dome. Sounds good though, let me know if you have any questions!

[@jean-marclariviere7618]

@@trilliumdomes Thank you Sir..for the response...i am looking at price sheet from the mill close to where i live, will not go to Big Box Store..will be using Hemlock...also since i have to stay below 192 sq. ft. if i don't want to ask for a permit...i will go with 15ft. Thanks so much in advance, now all i have to make sure it that the municipality says yes..my house is not traditional i also want my greenhouse to Rock...be well and have a great 2023...will keep you in touch, thanks again Sir

[@ronsheldon1418]

Awesome mate! You're a man after my own heart. I love your product and video. What about condensation issues. I could see myself living in one of these.

[@trilliumdomes]

I appreciate that! Yep condensation is an issue in all greenhouse just need proper ventilation so that’s no problem. Twin wall poly helps a lot vs single layered materials!
