The project is a house and clinic in Dennenchofu Residential Area, at the southern periphery of Tokyo, Japan. Dennenchofu were planned based on Ebenezer Howard’s ‘Garden City’ concept and lots were being sold since 1923. Fifty percent building coverage was mandatory to secure garden space for each lot. In the past it was populated with mansions built on large sites. However in recent years lots have been split by inheritance, reducing each lots’ space for gardens, to a point where there are no gardens at all. The site of the project was also divided by inheritance, which resulted in a ‘flag and pole’ site of about 90 m2. The lot is squeezed between adjacent houses with only a 2.5m wide alley as access from the street. RAA started the design process by examining ‘flag and pole’ sites around the site. In general, houses were built in the ‘flag’ portion of the site, whereas the ‘pole’ portion were used as the entrance and parking space, leaving no space for a garden. Moreover, the regular approach, built in a densely populated area, resulted in minimum natural ventilation and light exposure. View more View full description
