Based on Corporate Spirit of “Green, Open and Shared”, we proposed a concept of “a semi-open courtyard”, realizing a modern interpretation of traditional courtyard spaces. It has 2 parts: the East on ground is the reception area and tea room; its upper floor is the negotiation and recreation area. The West has sand table and the exhibition area. There is a courtyard in between enclosed by glass brick. A platform on upper floor connects buildings; the trees can grow into the second floor from holes on the platform, achieving the connection of spaces.
