This project is sales office of China's developer CRCC in Chongqing. Without too much decoration, this building is concise and elegant. Glass is the main material used for building facade and a floating black box will be composed of opaque back glasses upon transparent glasses in air visually. Before entering, visitors can already start to have interaction with the building since the roof with overhanging eave built by polished stainless steel could reflect things in front of the building. And due to the texture of the steel, the image of reflection on the roof is dramatic like a distorting mirror.
