The Fuzhou Shouxi Building is located in the center of the capital city of Fuzhou of Fujian Province, China. This complex location in the heart of the city results in many restrictions and regulations. In order to realize the new building with 400 apartments, a parametric design with a soft organic shape has been developed by changing the floor bands on each level, resulting in an undulating facade. The staggering of the floor belt gives the building a strong identity and recognizability.
