Current characteristics of idle residential building spaces in traditional villages in Beijing, China

With the accelerated development of urbanization, many village populations have flowed into cities, intensifying the "hollowing out" of villages, leading directly to the idleness and abandonment of residential building spaces. We take idle residential building spaces in traditional villages in Beijing as our research object, construct an architectural spatial characteristic factor system through research of the current situation and relevant data collation, and interpret the characteristics of the research object by adopting kernel density estimation and SPSS statistical analysis. Research shows that some aggregation exists for the distribution of idle residential building spaces in traditional villages in Beijing and that the spatial characteristics are distinctive. The results are as follows: (1) Most idle residential building spaces are traditional-style buildings built before 1979, and the courtyard layouts are mostly one courtyard. (2) Most idle residential building spaces have been somewhat damaged, adversely affecting the preservation of the spatial environment and the legacy of construction techniques in traditional villages. Therefore, protecting and developing traditional villages requires paying attention to the renewal and reuse of idle residential building spaces, effectively fostering sustainable development.
