Sorry I'm late offering the links to my favorite tiny home/deployable permanent/temporary

7. Might take me a few days because I'm old and slow,

but I'll get there. I had allowed my favorites list to become a tangled rat's nest from too often forgetting to be sure a bookmark went to the right folder. So I had a ton of sorting to do and I'm still not entirely done. I did notice a couple places that offered free plans for the true DIY-ers. If you have the time and manpower, a basic concrete dome home is not that hard to accomplish. Lots of rebar, chicken wire and then troweled on slurry in several well-cured layers. That is, if you don't have too many regs to worry about. Some people blow up a huge bladder like a balloon and spray/trowel crete over that. I've also read arguments in favor of fly ash over portland cement, too.

If I had all the $ in the world, I'd go for a Dome King with 2 or 3 interconnected bubbles around a semi-enclosed courtyard. They can be designed for the convenience of elders as well, with sloped foundations, wide doors, and even built-in flowerbeds all around. That really appeals to me.

Anyway, look for a third OP within the week more or less. It should be titled 'Even More Tiny House Urls' although of course most are not technically the Tiny House brand, just the general style.
