I do have experience building a small affordable structure. It's a 20' diameter (314 sq/ft), 7' stem wall, 14' total height, concrete dome structure. PM me if you want to view it. Mine was constructed without a permit, but it was legal as the size was within the counties limits for a accessory structure on ag land. I have since registered it with the tax department, and they assessed it at $13,600. So, it's on the record.
I intend to build more of them. The first one was a learning experience and I have a improved technique I intend to use. A permitted one with installed plumbing and electrical may be in the future. A fiberglass rebar called Gatorbar (which is available at Honsador) has just been certified for use on residential construction, which I plan to use in all future builds.
Once I build one where I'm 100% satisfied on the technique and process, and confident of my ability to reproduce it, I may start a LLC and see if anyone else on the island wants one. But that's a year or two off. While I experiment I'm just building accessory structures on my lots.
I'd rather not reveal what it cost to make, but the material costs were quite low. Notably, immune from timber price hikes. I suppose Portland Cement could suddenly become more expensive, but it seems to be a more stable commodity, so far.
It's round on the inside. See yurts to figure out how to make the interior design work.
There is a similar structure, fully permitted and on the books, down in Hawaii Ocean View Ranchos. It's a 30' inner diameter. There's some older ones up in Captain Cook, built using a different technique. One caveat about doing these permitted, is for some reason the county assesses their value as crap. Lowest grade on the books. Great for property taxes, bad for resale.
