These unusual buildings were designed by architect Piet Blom. Several dozens of such cube-shaped houses called Kubuswoningen were built in the Dutch towns of Rotterdam and Helmond in the midlle of the ‘70s. The total area of each house is around 100 square meters (1075 sq. ft.), though about a quarter of the space is unusable due to angled ceilings. In 2009 several cubes were converted into a hostel.
