The forms between the different buildings of the city were separated, creating a fragmented public space. This fragmented space is degraded and not rationally used, which can reduce people's quality of life and negatively affect the sustainable development of cities. This study is through urban street architectural boundary spatial analysis, multi-method convergence exploration, research spatial characteristics, classification and evaluation elements. The purpose of the study is to provide basic research for subsequent evaluation of differences among others. At the same time, explore the potential value of urban public space utilization and innovate a new model of street architectural boundary space utilization; Finally, it provides strong support for urban public works. This study takes the boundary space of frontage buildings as the research object, mainly adopts the methods of literature investigation, investigation and experimental research, and through definition and quantitative research, defines the definition of space and constituent elements, functional classification and cluster analysis of evaluation elements. The results of the study are collated as follows. 1) The components of the boundary space of street-facing buildings are mainly composed of three areas. the building surface layer, the transition area between motor vehicle lanes and buildings, and the isolation zone between motor vehicles and passages. 2) Clarify that definition and model of the boundary space of street-facing buildings. 3) Deduce that expression formula of the spatial model of the boundary of the street-facing building. 4) Sort out that spatial element of the boundary space of the building facing the street. 5) Classification and division of the boundary space of street-facing buildings from the functional dimension. 6) Sort out the evaluation elements of the boundary space of street-facing buildings, and cluster three factor components, namely "experience factor", "development factor" and "quality factor".
