The 16 unit complex is located in Western Tokyo in a hilly area dotted with L-shaped mansions and trees. Maisonette units face the street and step in relation to the slope. L-shaped green ss openings emulate the surrounding green areas. Studios feature ceiling heights changing along the slope providing a diverse sectional space.The units combine contrasting white panels and bare concrete walls. Steps allow the spaces to be changed by the residents. A self-supporting wall can be used as a walk-in closet. Materials and spaces based on a minimalism and the site provide a liberating lifestyle.
