CHONGQING SCIENCE HALL CHINA is located in the core of Western (Chongqing) Science City, serving conferences, exhibitions and scientific exchange. The project responds to mountainous terrain by integrating structure and program into a clear spatial system. A three-storey, 72m long-span steel frame vertically organizes exhibition halls, multipurpose spaces and conference areas into a flexible framework. Two 13,000 m² column-free halls provide adaptable large-scale venues. An elevated ground connects north and south zones, forming a continuous public interface.
