geodesic domes were a big thing in the 1970s/80s and were about the same price of a mobile home/trailer home. They could be easily assembled by a couple of people w/a small group of friends in a weekend, and added onto as needed. The problems came with zoning as anything novel is more difficult for the local inspector to assess, and the internal angled walls made for wasted space, so anything taller than a low desk (dresser, cabinet, or refrigerator) against an outside perimeter must stand out from the wall. Another option is to just buy an RV and/or a camper + a truck to pull it. The survivalist crowd has done quite a bit of this -- buying remote rural lots with good water and farm land and setting up a homestead.
