They may look like they’re about to topple over, but these cube-shaped houses actually form a small village within the city center of Rotterdam, NL. A modern concept designed by the late architect Piet Blom, and constructed in 1984, this spectacular set of buildings represents an urban forest where around 40 traditional houses are tilted at 45-degrees to rest on a hexagonal pylon.

The innovative design transforms the idea of the traditional structure by playing with angles and convention.
