This project is located in Chongqing, a city famous of mountains and rivers. Therefore, we name the project "Water Side". As a design concept, water always participates in it, forming a unique design language. At the indoor meeting area, the ceiling looks like water waves. These tiny lines are unlimited extension in space. We use mirror with stainless steel material to depict the texture of the lake, just like the ripples caused by the wind blowing on the lake surface, in which human reflection is transformed into an image in the water, intersecting the virtual and the real.
