Abstract: Urban building space is an important carrier of urban function. In the process of urban renewal and development, we need to improve the relationship between inheritance and sustainable development, and adhere to the harmony and unity of man, city and nature. Therefore, building space must be regarded as an organism composed of organic urban modules, but not simply as an inorganic combination of simple functions. At the same time, the fundamental goal of establishing the organic spatial form order is to improve the urban spatial quality, improve the environmental quality characteristics, and promote the sustainable development of urban spatial planning; the urban building itself is an organism, so how to make the organic integration with the city in the architectural design is crucial. This paper will take this as a starting point, combined with the project, to discuss the specifi c practice of the design, for reference.
