The five-story apartment complex contains 101 rooms. Architect Manabu Chiba, who also designed the eastern unit (bottom right of floor plan), oversaw the project. The northern unit was designed by Shinichi Ogawa (top right), and the western unit by Ryue Nishizawa (bottom left).

 

East Unit by Manabu Chiba

The east unit is located on a wedge-shaped corner with a relatively good view. Chiba focused on providing its residents with a sense of openness, whilst granting them privacy. Each room receives generous glazing on the exterior. Inner, private rooms are protected by the engawa-like perimeter space.

North Unit by Shinchi Ogawa

The north unit is a narrow rectilinear building that extends across the rear side of the site, behind the two more prominent units. The minimal studio-type rooms on the first to fourth floors are undivided except for a box in the core that contains a bathroom and storage space. On the top floor are two long penthouses.

The rooms on the fifth floor are only 2.1 meters wide (6.9 feet), but extend to create a long interior space with an equally sized parallel terrace.

 

West Unit by Ryue Nishizawa

The west unit by Ryue Nishizawa is a stark exposed concrete building. Its chaotic forms bulge in and out, creating jagged gaps where the blocks forming the building appear to collide. The irregularly-shaped rooms look into these sharp interstices, creating unexpected views and adjacencies.
