The project is the main house in Qingping Hutong, Beijing. Known locally as a da-za-yuan, which translates as “a big messy courtyard shared by several houses”. The owner’s parents, who suffered from Alzheimer’s disease, used it, and was to be renovated by the house owner. However, it turns to a series of problems caused by structural damage. The difficult point is to explore the best possible standard of a Chinese traditional courtyard house, that is reasonable for co-living between the younger generation and elderly, sick parents, within a limited living space. As well, as interpreting a da-za-yuan case study that is China, who has a big challenge of aging population issue.
The plan is to construct an additional metallic roof and we keep its original wood structure and space plan to keep the old memories from owner’s mother. New structure added into the second floor, with 3.8m in height to expand the living space. Using larger glass window façade and a series of accessibility designs, the architect solved the problem of dark rooms, a common fault of hutong houses, by adding larger window façade to create a light-well and a perforated wood staircase. In particular, round roof scuttles which are made to optimize daylight penetration, is merged in unique oriental aesthetics to traditional form of courtyard. On the outside of the roof scuttle, the wall and roof were covered by the green plants from rooftop to the bottom as a “Z” shape, which gives the shape of hope. As CAA founder Liu Haowei described as “old Beijinger may like walking in the sky”.
The result, this project embraces unique needs and restrictions of each site, traditional and livable, balancing between historic preservation and modern living requirements. This case is to breakthrough CAA principal, futuristic style as it always is. It is the latest attempt to build integration in limited space to create a new generation of hutong life.
