Architecture, Building and Structure Design Vanke Metropolis Seasons Sales Center by Feng Yang Vanke is a sales center covering 1600 square meters. The building responds to a site shaped by a canal, a wetland park and nearby elevated roads. Modern door frames are stacked in layers, and their sequence is adjusted by mathematical parameters to create a gradual transition. The frames extend inside and are reshaped into an arc-like lobby, which is completed by hanging acrylic panels and public installations. Brushed copper-like stainless steel, dual-layered insulating Low-E glass and golden limestone form the main interface. A garden with a swirl-shaped layout closes the route.
