The project is located in the core area of Nanjing Jiangbei New District. In the dense network of the road system, a shared courtyard is created responding to the demand of centripetal medical research community. The site area is 28,624㎡ and the GFA is 30,125㎡. An interaction between courtyard and street is presented. The architecture is more like a microcosm inside the city via its blurred boundary, rather than being an aggressive landmark. In this miniature community, sustainable social activities and restrained urban space are expressed simultaneously.
