Abstract: With the development of national fitness activities and the improvement of people's living standards, the development of sports buildings is in full swing today. However, the traditional sports venues have exposed problems such as inconvenient transportation, single function, decentralized facilities, low utilization ratios, and the requirements of urban land intensification have re-examined the configuration of sports buildings. It is a new design concept to use the building height to put the mass sports function into more compact vertical space. Based on the appropriate space scale and functional characteristics of the national fitness facilities, as well as the structural technology and material application of today's long-span buildings, the design strategy was studied from the perspective of "overlapping space", taking the comprehensive sports halls with 4 to 5 stories as a typical representative. While promoting such buildings to provide public space and vitality for cities, it also achieved the sustainable development objects of today's large-scale public buildings.
