Good design is to be a part of the surroundings rather than an additional part. Vanke Emerald Metropolis, in CBD of Yuzhong district, Chongqing, totally covers 23,500 square meters, including the floor space of 168,000 square meters.Chongqing's landscape on the external wall allows the building to have a conversation with surroundings, further establishing relationship each other. The tower that saliently features vertical white metal lines and blue glass curtain wall develops an uneven and staggered riverside skyline, reflecting Chongqing's valley.
