World's Wildest Houses IV

Joshua Tree, California

You wouldn't expect to find a modern 1,700-square-foot home with two bedrooms, two full bathrooms, and heated concrete flooring on the other side of the unassuming boulder (shown, bottom). Though the facade of this house completely blends with the rough terrain, the back of the house (also shown, top) offers up ultra-modern design and full views of the desert.
