Space and Culture: Isomerism in Vernacular Dwellings in Meizhou, Guangdong Province, China

Taking Hakka vernacular dwellings as an example, this paper discusses the relationship between culture and architectural form. Using survey data from 2,189 traditional villages in the Meizhou region, the authors identify seven types of dwelling and their spatial distributions. Four housing types (Hengtang, Lung Wai, Bar and Pillow) have a high spatial overlap. Architectural morphology, with respect to symmetry, unit design and prototypes is then discussed. The four major dwelling types share the same cultural essence despite having different physical forms. This confirms the phenomenon of isomerism in architectural morphology. The authors hold that the homogenesis of vernacular dwellings, or the ″spatial prototype″ as a symbol and carrier of culture, strongly controls the consistency of architectural design. Meanwhile, heterogeneity reflects specific strategies of housing construction. It gives residential spaces adaptability to specific sociocultural and natural environments. Meanwhile, it exhibits itself indirectly in the form of diversity. Isomerism offers an appropriate mechanism through which vernacular dwellings can balance the needs of the top-down national system, bottom-up family needs, and the natural environment. This brings a new perspective that increases our understanding of vernacular dwellings.
