In the 1970s, the American architect John Hejduk designed several Wall Houses. In the end, only one was realized.
In 2001, Wall House #2 was built in a residential area on the Hoornsemeer in Groningen. Central to the design is an enormous wall of 18.5 meters wide and 14 meters high, on which the various rooms are suspended. At the same time, this wall connects the rooms with each other. The entrance is not at the front, but at what is perceived as the rear of the building.
