This architecture is a four-unit rental apartment for single person households in central Tokyo. It was designed based on the Japanese philosophy of Chisoku. And it was designed with bare concrete frame that maximize the limit of the site, and also with wooden booths where minimum living facilities and appliances were hidden inside. As a result, a freely space with a height of 3.5 meters was created. The residents use this blank space as an opportunity to enjoy their lives and to use it to collaborate with the local community. The project was designed to capture this blank space.
