The Dutch certainly like to experiment with design, and their planning regulations seem to encourage it. One of the most extraordinary and imaginative housing projects in the Netherlands has to be Piet Blom’s Cube Houses, or Kubuswoningen, in Rotterdam. Completed in 1984, this housing block was designed to be high density. By tilting the cube of a conventional house 45 degrees and resting it upon a hexagonal tower, the houses achieved small footprints but large total surface area inside. Having already completed test versions of the houses in 1974 and 1977, at Rotterdam the complex is much larger with 38 small cubes and two so called ‘super-cubes’, all attached to each other. These houses attract a great deal of attention in Rotterdam, to such an extent that one resident has made a living by opening their house up to visitors as a ‘show cube’. In 2009, the larger cubes were converted into a youth hostel by Personal Architecture run by Stayokay.
