I don't want a "tiny" house. I think i'd go crazy. Not because I want a lot of stuff, or [View all]
even have a lot of stuff, but because I like a little space and I don't want to live right on top of the cats' litter boxes (we have 5 cats, must have 3 litterboxes, minimum).
I get pissed off quickly if I'm crowded, cracking my elbows on door frames, etc.
Now, we currently rent a small house, about 760 livable square feet (basement is not livable for humans - the ceiling is so low my husband can't stand up to his full height (6'4"
nor can I if I'm in heels), but the cats are happy to play there and visit two of their three aforementioned litter boxes).
However, I think that if we had use of both the upstairs and 'downstairs' (basement), that would be AMPLE space. It's just the two of us and our five felines. Huge amount of space, if used correctly / designed well. If we even had a full 1000 square feet, it would be comfortable. We'll probably end up with a little more because it'd be nice to have an annex office ... but again, if we had about 1250-1500 sq. feet (including the office) it'd be perfect.
Even if we could afford a super giant mansion, I don't want one. I want a very energy efficient, extremely well built, convenient home that doesn't take weeks to clean. And that has only a few functional, regularly used items be they furniture, clothing, home appliances, etc.
How about you? Could you live in a "tiny" house? One of those tumbleweed ones ( http://www.tumbleweedhouses.com/ )? What space do you think you need to feel personally comfortable but not extravagant and wasteful?
