Renovation of Traditional Residential Buildings in Lijiang Based on AHP-QFD Methodology: A Case Study of the Wenzhi Village

The rapid growth of tourism has led to the transformation of numerous traditional dwellings in Yunnan into commercial lodgings, presenting a challenge to the preservation and inheritance of traditional culture. However, the existing renovation practices lack scientific data support and rely heavily on architects’ subjective designs. Thus, finding a scientific and stable approach to maintain the traditional residential characteristics becomes crucial. This study focuses on the renovation of Wenzhi villagers’ residences in Yunnan as a case study. It employs the innovative AHP-QFD design methodology to explore a more scientific and objective method for preserving and promoting the features of traditional dwellings in commercial renovations. Initially, the study assigns weights to the commercial renovation objectives—local traditional features, architectural functions, sustainability, and comfort—using the hierarchical analysis method (AHP). Subsequently, specific design features are derived from transformation requirements through interviews and questionnaires with residents, tourists, government officials, and experts. The innovation of this research lies in the application of AHP and QFD models to the innovative design of commercial renovations for traditional dwellings in Yunnan, resulting in a set of systematic and scientifically supported decision-making methods for renovating and preserving traditional buildings in the region. The study’s findings reveal that building geometry and dimensions, skilled traditional craftsmanship, and flexible and expandable solutions carry the highest weight in design. The application of the AHP-QFD model in commercial transformation design effectively balances the preservation of traditional culture and the pursuit of commercial value. It offers a feasible and innovative design solution for commercial transformations of traditional houses in the Yunnan region, ensuring the preservation of cultural heritage while enhancing commercial appeal.
