The skin of the building acting as the boundary between us and the space, it defining the feeling from us towards space, the skin of the building - such as ceiling, flooring, facade, paving defining the relation between us and the sky, soil and the air. As one of the most public related building in Shekou area we are quite intrigued by this definition of building surface. So we created a building which is one single continuous surface that growing from one strip of landscape, by different treatment this surface created varieties of indoor and outdoor space, as well as all vertical circulations, and through different design of this surface we bring different identification in to the space it created.
