Bar none, this house in Colorado looks like the most difficult-to-furnish place in the world. It is shaped, more or less, like a six-point star, which basically just means that all the walls leads into to some kind of acute angle. To be fair, the current owners have done a pretty good job of it. The place also has its original '60s wood paneling and appliances, and it's on the market for $599,000.
