This Floating, Off-Grid Prefab Can Be Assembled in Just Two Days2 of 10

While the design is suitable for life on land, the owners of this one decided to mount it on a floating catamaran, which can be moored to a buoy or sailed at speeds of up to four knots. The tiny house, called Altar, is currently offered as a rental on Airbnb.
