Self-adaptability and topological deformation of Ganlan architectural heritage: Conservation and regeneration of Lianghekou Tujia village in Western Hubei, China

Abstract

The authenticity of architectural heritage is interpreted differently in diverse cultural traditions. Can this inspire the conservation and contemporary regeneration of architectural heritage to adapt to the changing needs of modern life and society, rather than static exhibits in museums? This research focuses on Ganlan (pile-built timber construction) architecture to demonstrate how adaptive conservation and regeneration can keep traditional construction systems living and sustainable. Ganlan, a vernacular architectural archetype in the humid subtropical regions of Asia, has the following common features: free plans with an assembling frame structure, open and interactive envelopes to cope with the hot and damp climate, and stilts to deal with the rugged terrain. This research employed a threefold method of field investigation, topological deformation, and experimental design in examining Lianghekou, a historic Tujia village in Western Hubei, China. The findings reveal that Tujia people build their stilt houses with adaptable features to meet the changing functional requirements and variable topographies. These traditions can be transmitted into the contemporary design, as our experimental design illustrates. The self-adaptability and topological deformation of Ganlan architectural heritage demonstrate a unique perspective of understanding authenticity, and contribute toward innovative application in the conservation and regeneration of vernacular architecture.
