Abstract:Space defensive character is a prominent feature of modern Lingnan country estate as a family living space, reflecting the meaning of the times and the state of social life in the region. Studying the relationship between defensive demand and architectural space construction is of positive significance for understanding the generation logic of modern Lingnan country estate and enriching the historical theories of Lingnan garden. Through literature research, field research, scene analysis, graphic analysis and other methods, this paper sorts out the background of the formation of space defensive characters of modern Lingnan country estate, and reveals the form of architectural defensive space from four aspects: its relationship with environment, boundary, architecture and courtyard. Furthermore, the paper compares the differences between modern Lingnan country estate and urban garden in defensive space treatment methods, explores the differences between urban and rural areas in the “function-space” fusion mode of Lingnan private home gardens, and further discusses the space generation logic of Lingnan private home gardens.
