Designing in a world of cultural diversity demands a break from traditionally Western-centric paradigms. This project explores a more respectful approach to design, deeply rooted in participatory methodologies and acknowledging the coexistence of diverse realities—a "pluriverse." The research journey delves into the complexities of participatory and decolonizing design, emphasizing the importance of recognizing multiple worldviews. The ongoing development of the CHAMPS cultural heritage mapping platform stands as a testament to these principles in action. The Kuching, Sarawak community in Malaysia actively participated, enriching the platform with their unique insights and lived experiences. The culmination of this work offers a reflection on design that bridges theory with hands-on practice, emphasizing cultural respect and inclusivity.
