Not interested in the RV/travel thing. Any traveling I do will be as always, via small/efficient car, etc. Not looking to drag a place around and go through all that. Not looking to commune with others, either. Not interested in being part of an RV/retirement park gang.
As for lofts or any sort of upper/elevated areas, anything I've designed has been stair-based (both code-compliant and not-so)...I don't trust myself on a ladder
now, let alone 15-20 years from now.
I'm really not into the "tiny house" thing as it's been defined/portrayed (the narrow, on-wheels thing with cramped ceilings, etc. I'm more into just small, but open, houses...no ladders, no crouching, etc. I don't want 200 sq. ft on wheels., but I don't want/need 1,000+ cookie-cutter sq. ft. in a subdivision either.
