House in Sangenjaya is a minimalist architecture project located in Tokyo, Japan, designed by Schemata Architects. There is a dead-end street sandwiched between two mid-rise buildings at a three-minute walking distance from Sangenjaya station. Peeking into the narrow street, one finds the space suddenly opens up to the sky, and the 52-year old building quietly standing at the dead-end. The client’s grandfather had been using the building as his clinic and a private house for his family for a long time, before the client inherited it and asked the architects to do the renovation. Considering its location in the city, a reasonable decision would be to build a new tenant building or rental apartment building with an increased floor area, but the client wished to keep the existing building, which had been loved by the local residents for a long time, rather than prioritizing business profits.
