⭘ Multi-base surface urban space model emerged in the rapid development of the city, the space model is mainly for the high-density urban land scarcity and the traffic problem of the contradiction between people and vehicles, although to a certain extent effectively alleviate such problems, but also brought many other problems, such as the space below the base surface is dark, the space is poorly identifiable, the space above the ground above the base surface of the space accessibility is weak, the use rate is low and other problems.

⭘ This design study, based on the research of theories and the investigation and analysis of completed cases, summarizes the spatial design principles and design strategies of community public service facilities under the perspective of multi-surface, taking into account the spatial demands of community residents and the pain points of multi-surface urban space structure. The design is also verified with specific plots and design conditions in the design practice of public service facility space in Qianhai Shoukai District. It also explores how to solve the inherent problems of urban space model and provide diversified and quality community service facilities for the community residents under this urban space model.
