This case is located in Chongqing, a local art experience Museum. We wanted to establish a spatial relationship symbiotic with nature. Chongqing's geographic features were taken as the design source, and the space and functions connected with a bionic skin, so as to realize the experience of seamless connection and natural transition in the reception hall, rather than the existence of separate spaces.The ups and downs bring out the extending and layering trend of Chongqing, which is also the most typical feature of the mountain city.
