Architecture, Building and Structure Design Dahua Park City Exhibition by Shanghai Puspace Architectural Design Co Dahua Park City is an exhibition building set between mountains and a lake in Kunming, China. The main volume is stilted above the sloped site, while multi-layer terraces and long French windows open wide views toward the surrounding landscape. The curved facade is formed from 3,276 triangular aluminum panels, each carrying a different perforation pattern. The panels were joined in pairs to simplify installation. The interior route creates a spatial sequence that frames the lake view. The gross floor area is 2,200 square meters.
