On the entrance floor of the building there is a slft-service café, and the first floor is occupied by offices.
From this level upwards there are 140 one-room flats each consisting of a capsule measuring 4 x 2.5 x 2,5 metres.
The 140 capsules are hung on the concrete towers that contain the vertical communications; they are identical, prefabricated steel cells filled with bath unit, conditioning system and colour television. Constructed at Osaka, they were transported to Tokyo by truck. The assembly time for each capsule was three hours. (Within one month the capsules were all sold, as city pied-à- terre for business men, professional people, etc.).
