A seven-unit shared house in a residential district of Shinjuku, Tokyo. Four boxes containing seven rooms and bathrooms are stacked on three levels inside a large 10m high box, leaving gaps open around them. The common spaces-a workshop space on the first level, terrace on the second level, and kitchen on the third level- are all connected and perceived as one space by means of a 9,300mm high void within the entrance. The gaps are finished in the structural plywood, like the common space, and residents can freely install the furniture in there or leave them open, as they like, to fit their lifestyle. The interior screened from the street before the house by means of a waterproof, semi-transparent tent membrane. The membrane allows light into the interior and can be unzipped to give the common spaces connection with the city.
