This house might look like it's straight out of the future, but it's actually based on the oldest house design in Japan: the pit dwelling.

Pit dwellings were built by placing a steep thatched roof over a hole dug in the ground. That's just what architect Makoto Tanijiri did for a family in Saljo, Japan.

As you can see, what appears to be a solid pyramid sticking out of the ground from the street actually sits on a room with windows on all sides. I'm not sure I'd want to live in a home designed quite like this, but it's pretty awesome nonetheless. [Yatzer via Book of Joe]
