Based on the functional requirements, the plan integrates the entrance hall and the model display area into one group, the negotiation area, the water bar and the signing area into another group, and the office area remains relatively independent. Through the staggered layout, each functional block encloses a courtyard space of different shapes and sizes. The building encloses the overall outline with a complete exterior wall, and forms a high and low sloping roof form by stretching the roof. The design recesses the entrance space in the courtyard to increase the sense of spatial hierarchy. Combined with the design of the landscape courtyard and the pool, it finally forms a courtyard-style building with an overall appearance, a staggered interior and rich space.
