Itty bitty no-one-should-probably-fit-in-them abodes are apparently all the rage now, especially according to our TV overlords. FYI has just launched new episodes of "Tiny House Nation" (see local listings) which helps people build their "dream" homes under 500 square feet. FYI also airs "Tiny House Hunting," which we assume is similar to "Tiny House Hunters," now airing weeknights at 10 p.m. on HGTV. On a recently epsiode of that show a woman had to chose between living in a yurt — a yurt! — made from a kit and a home made from mud and barbed wire.
