There are two sets of cubic houses, both designed in architect Piet Blom. One is in Helmond, Netherlands, but the more famous set is located in Rotterdam. The cubes are rotated 45 degrees, and rest on a base shaped like a hexagon. There are 38 cubes, as well as 2 super-cubes. All of the houses are attached to each other and represent a village of tree-shaped houses, making a forest.
