Office Building for Shihlien Group, Huaiyin City

Álvaro Siza 


Like a coiled up, sleeping dragon, the new headquarters of the chemical industrial group Shihlien rise in the center of an artificial lake in the city of Huaiyin, in the Chinese province of Jiangsu. The idea of placing the building over the lake was present in the master plan for the complex, because the factory needs a significant water reserve to guarantee constant production. The building, with offices organized in two levels, consists of an elongated strip that curls like a horseshoe and is connected to the rest of the areas by two perpendicular footbridges that extend the urban pattern of the industrial complex. With a marked sculptural character, the curved lines delimiting the main volume look towards opposite directions, generating circulation spaces that flow throughout the perimeter and perspectives open to the industrial landscape.

Conceptually speaking, the building floats over the water, but constructively the structure rests at the bottom of the pond, eight meters deep. The apparent lightness conveyed by the lake’s reflection is intensified by the lower, cantilevered platform, revealing a space between the water and the building.
