The sensational journalism tends to highlight people who live in human versions of insect hives.

I've lost track of how many Youtube videos I've seen about people living in -- and extolling the virtues of -- so-called "tiny houses." Many are about 10 feet by 10 feet -- 100 square feet. But those all seem to be in places like southern California. If you think about it, a minimal standard bathroom, as found in 1950s post-war tract housing, takes up 35 square feet (5x7). At least two of the four walls have to be interior walls, so just a bathroom really takes about 40 square feet out of the floor area of a house. Many of these so-called "tiny houses" are really more like "tiny bedrooms." There's one, in particular, that I remember because the person who made the video describes the owner of the "house" as sort of a guru of the movement. But -- his tiny house doesn't have a bathroom. He has a composting toilet located outside of the house. His shower uses rain water and is also outside of the house. The "house" has no kitchen -- he cooks and eats outdoors, under a tarp.
I need, at a minimum, a real bathroom, with hot and cold running water; a real kitchen, with hot and cold running water, a refrigerator, and at least a decent size microwave and a toaster oven; and room for a gun safe and reloading bench.
