Actually, I was channel-surfing this past weekend and I stumbled across a show on the Home and Garden network about “small spaces” that was featuring one of these houses and a couple who lived in one of them. I think the house they featured was the one described as “XS House.” Check out the descriptions of these houses to get an idea what I mean. “XS House” is 75 square feet, and it featured (at least on the HGTV show) a sleeping loft for two (which, with the low headroom, looked a hell of a lot like a coffin to me), a hot plate for a “kitchen,” and a “composting toilet” that was really a small metal garbage can with a lid you can open with a foot pedal– the kind of thing you might see in a doctor’s office. I’m sorry, but that’s a deal-breaker for me. I’m not going to squat and shit into a tiny garbage can in my tiny house.
Still, I could see some of the other designs as a cabin in the woods kind of vacation home or as a studio/office space in the backyard. As long there was a real toliet installed or at least nearby in the “big house.”
