This case is an office space of a high-rise building. The client's request to us is to "waste twenty percent of the space first", and to do more space combination in hard decoration. We know that by this joke the client actually hopes to improve the tone and quality sense of the whole space through designing, so designers fully take the combination of functions into account when deploying the entire spatial structure. In the entrance hall, the information desk, the meeting room and the negotiation room, a lot of dislocation, abstraction, geometry and composition have been done, thus forming a new combined conformation and functional body.
