The U.S. based multidisciplinary architectural firm Sasaki won first prize in the international design competition for Beijing Olympic Green. The Olympic Green is the primary site of the 2008 Beijing Olympic, which occupies an area of 1,135 hectares, including a forest park, National Stadium and Olympic Village. Sasaki focuses on post-Olympic use and sustainability, seeking to balance East and West, ancient with contemporary, development with nature, and existing surrounding context with the Olympic Green, both poetically and programmatically. The master plan includes areas for residents and visitors in daily lives and for further development for commercial, cultural, and hotel uses after the Games, and adopts "Green design", aiming for self-sustainablity and low-cost maintenance. Sasaki's scheme is now the basis for implementing the Olympic Green.
