It is a large housing complex (308 units) built in front of a station in the suburbs of Tokyo. Its main features are the main entrance hall with 5.5m high glass walls and the large courtyard named “the moon terrace” surrounded by 3 housing buildings (14F). Our tasks included making a difference from other nearby housing complexes by creating a special night scene in the courtyard. In addition, we achieved low running cost and easy maintenance by using only LEDs and choosing floor-embedded fixtures.
