I have a 2700 sq ft loft, plus a two car garage and a 400 sq ft deck (fuck, my home gym alone is bigger than a lot of these microdwellings). I don't have very much furniture. Frankly, as gluttonous as it sounds to have all that for one man (+two cats), I fuckin love it. It's wide open and not cluttered, about as peaceful as a home can be in my opinion. I don't get claustrophobic on airplanes or in elevators, but I get it bad in a cluttered home. The top floor of my place is a 900 sq ft room that is used as a living room, dining room and kitchen, with floor to ceiling (11 ft ceilings, too!) windows on one end. It's the opposite experience I had growing up, where there were always a bunch of kids, we messed the house up all the time, and the only place I had to myself was a tiny bedroom. The smallest place I lived was a 600 sq ft studio, which wasn't that bad, and was all I could afford on a graduate student stipend. But at this point in my life, I don't think I'd have an easy time adjusting back down.
