Cube Houses, Rotterdam...

Cube houses are a set of innovative houses built in Rotterdam and Helmond in the Netherlands, designed by architect Piet Blom and based on the concept of "living as an urban roof": high density housing with sufficient space on the ground level. Blom tilted the cube of a conventional house 45 degrees, and rested it upon a hexagon-shaped pylon. His design represents a village within a city, where each house represents a tree, and all the houses together, a forest.
