The Nakagin Capsule Tower Building, built in the early 1970s, comprises 140 self-contained prefab capsules attached to two interconnected concrete towers. Capsules were used as homes and as offices.

Prominent defenders of the building have included New York Times architecture critic Nicolai Ouroussoff, who said that “like all great buildings, it is the crystallisation of a far-reaching cultural ideal” and “stands as a powerful reminder of paths not taken, of the possibility of worlds shaped by different sets of values”.

However, the unique building is now set to be demolished on Tuesday 12 April, TimeOut reports. Some of the individual capsules may be preserved as part of architectural history.
