Folding House

Another one that you can't exactly call building your house, but if you are in a real hurry this will do the trick. You just unfold it, really. The Habitaflex house comes complete with bathroom and kitchen fixtures plus heating, lights and water heater. The outside is quite the plain Jane, but inside is cozy with all wood paneling. They cost about $40,000. I guess you haul your furniture, stove and fridge in the back of the truck.
