In the architectural design of Cui Kai, architects consider using architectural modeling and spatial language to deal with the relationship with the specific urban environment, and pay attention to using the dual architectural language of eastern and western cultures to express the position and functional characteristics of FLTRP in the cultural exchange between China and the West. The second phase of the building has created a new spatial form under the restriction of retaining the original structure. In the design, both the landscape value and humanistic value of the building are taken into account, the architectural vocabulary is consistent with the first phase, and the external decoration and internal decoration of the building are further scrutinized, so that the two become a harmonious and mutually distinctive complete architectural art work. Mr. Kengo Kuma, the architect of Sanlitun SOHO, is a famous Japanese architect and has won many international awards. The project embodies various materials and curved appearance of Kengo Kuma style, and expresses a natural and organic whole language. The urban lifestyle and SOHO cultural concept advocated by SOHO China have formed a strong trend, which is also related to the historical and cultural background of Sanlitun. Sanlitun SOHO stationed in Sanlitun has played an important role in promoting the commercial and consumer flow in Sanlitun.
