This article explores the richness of Réunion’s architectural and cultural heritage, highlighting the gradual disappearance of traditional housing in favor of more modern constructions, sometimes to the detriment of vernacular crafts. Based on two interviews with a museum director and an architect, it highlights the tensions between preservation and modernization of this island heritage. The analysis of these exchanges is combined with an art-based research project, intrinsically linked to the question of mobility, which aims to reactivate these skills through the construction of a mobile art studio. Produced in close collaboration with some of the last craftsmen to master these techniques, the article details the construction of this studio using local techniques and materials adapted to new uses (wood shingles, endemic woven bamboo, vetiver). Through this collective creative experience, the author reflects on the importance of transmitting and reactivating these heritages to meet the challenges that Réunion Island is facing today, particularly the environmental ones.
