Nikotama Terrace Cooperative House / Okuno Architectural Planning

The Nikotama Terrace is a cooperative house located on the hillside of the Kokubunji cliff line that runs from Futakotamagawa to Kinuta. The site faces the slope called “Mamushizawa”, which used to be a valley, and is protected by the cliff line ordinance. It is a green place, like a mountain, surrounded by native species of the Musashino Plateau. There is also a large retaining wall on the site to eliminate the height difference. The main concern was how to confront this retaining wall and the building while making the best use of the height difference in the surrounding area? The design answer came as a row house (10 dwelling units) with a green valley.
