This house in Lubbock, Texas was the brainchild of Robert Bruno. He actually spent twenty three years designing and constructing it. The end result is a thing of beauty. Never mind the fact that it looks like a gigantic pig, though.
These are actually 32 houses which are all attached to one another. You can find this in Rotterdam, Holland. The Cube Houses were designed back in 1984 by Piet Blom. Each of the houses have 3 floors.
