Research on the Sustainable Renewal of Architectural Heritage Sites from the Perspective of Extenics—Using the Example of Tulou Renovations in LantianVillage, Longyan City

A novel methodology using extenics principles successfully addresses the challenges of renovating Fujian Tulou, China’s unique multi-story earthen buildings. The study demonstrates that extension transformation techniques—such as divergent tree and conjugate pair analyses—can resolve contradictory problems in renovation design, including functional adaptation and material constraints. Applied to Lantian Village’s Tulou renovations, this approach extends the buildings' service life while preserving cultural heritage. Findings highlight that sustainable renewal hinges on resolving condition-objective-design contradictions, offering a scalable model for other architectural heritage sites. This work advances both the practical application of extenics in conservation and theoretical frameworks for heritage preservation.
