One of the tiniest tiny houses I've seen, a 6 x 6 ft dumpster.

How sad that someone is living in a dumpster. 

Actually, this is a life-affirming story:

Until this summer, the green dumpster was even less descript than it is now. There was no sliding roof; Wilson kept the rain out with a tarp. He slept on cardboard mats on the floor. It was essentially, as he called it, “dumpster camping.” The goal was to establish a baseline experience of the dumpster without any accoutrements, before adding them incrementally.

Not long ago, Wilson was nesting in a 2,500 square foot house. After going through a divorce (“nothing related to the dumpster,” he told me, unsolicited), he spun into the archetypal downsizing of a newly minted bachelor. He moved into a 500-square-foot apartment. Then he began selling clothes and furniture on Facebook for almost nothing. Now he says almost everything he owns is in his 36-square-foot dumpster, which is sanctioned and supported by the university as part of an ongoing sustainability-focused experiment called The Dumpster Project. “We could end up with a house under $10,000 that could be placed anywhere in the world,” Wilson said at the launch, “[fueled by] sunlight and surface water, and people could have a pretty good life.”
