Reusing the Ghoufi’s vernacular buildings within the context of sustainable conservation, an action put to the test

Purpose Vernacular architectures are now seen as sustainable construction models for their quality and environmental solutions. This study examines Ghoufi’s Chaouie constructive culture, which adapted to harsh climates by optimizing resources and integrating vegetation, construction and animal husbandry. Yet, modernization efforts have often endangered this heritage through harmful rehabilitation. Our main goal is to preserve this resilient architecture through sustainable conservation that respects its cultural integrity. Design/methodology/approach An experimental method, based on the principles of integrated conservation, was employed to evaluate the reuse and readaptation potential of vernacular buildings. The research involved an initial discovery phase to examine the building practices, environmental context and Chaouie cultural heritage. Evaluation is conducted through a pilot study, where we conduct a rehabilitation trial on a model house, followed by a public survey, to refine the experimentation and obtain reliable and quality results. Findings The study concludes with methodological guidelines for a sustainable conservation strategy for Ghoufi. The findings demonstrate the feasibility of reviving traditional techniques, leveraging local expertise and resources and promoting environmentally responsible practices in the conservation of vernacular architecture. Originality/value The study lies in its holistic, field-based approach to sustainable conservation, centered on Ghoufi’s cultural and environmental context. Unlike prior interventions, this research integrates traditional construction, Chaoui community values and ecotourism as drivers of sustainable territorial development. It demonstrates the feasibility of reusing vernacular structures through an inclusive, community-focused conservation strategy that preserves Ghoufi’s identity while supporting long-term sustainability.
