Vernacular dwellings are an extremely important building type worldwide, and as an important carrier of the daily life of the vast rural population, they concentrate the local traditional building craftsmanship and the appearance of rural life. By tracing the construction and use of vernacular dwellings, it can provide useful clues for reconstructing the weak community relations in modern society. In the studies on residential houses, researchers often select official-style buildings located in the city and residential houses in the core of the region as the objects of study, and less research has been conducted on ordinary vernacular residential houses. Therefore, this paper selects a common village settlement located in the Lingnan sub-region, China as the research object, records the original information of the settlement, and restores the appearance of the dwelling with computer technology, and further analyzes the vernacular settlement in terms of planning and design, construction technology, and ecological characteristics, in order to comprehensively interpret its structural technology characteristics and cultural connotations, and provide useful assistance to policy makers and planning and design practitioners in the preservation and cultural transmission of historical buildings. Vernacular architecture has gradually disappeared in the context of modernization, and the study in this paper is also a blueprint to keep the backup of vernacular houses in Lingnan sub-region.
