Hey, if you like living in a dumpster...
I don’t get the derision. This is a great solution for an unmarried young urban professional just starting out in life. Most of those people work all day and dine out at night - only really needing a place to sleep at night and maybe hang out reading books on a raining Saturday or Sunday morning. Or an elderly in-law who wants to be close to her adult child but not be an interfering busybody getting in the way of everybody in the main home. Just put the unit in a corner of the backyard and hook up some utilities. Perfect!
