Historic community is a historical lot with mainly residential function, which retains the material space of local historical style characteristics, is the material container of local residents' urban life, and is also an important spatial carrier of local cultural heritage. Based on the perspective of spatial ternary dialectic theory, the historical community is disassembled into three major spaces, namely physical space, spiritual space and social space, and the concept of balanced development of the three major spaces of the historical community is proposed to achieve the overall renewal of the historical community. This paper takes the historical community of Xuejiawan in Shantang Street, Suzhou as an example, and summarises the current situation and problems of the three major spaces in Xuejiawan, initially explores this experimental renewal concept and proposes a detailed renewal strategy.
