This article explores the significance of prototyping methodologies in participatory design projects, with a focus on the European Fund research project SMOTIES. This project involves a consortium of 10 partners who developed tools to establish a shared methodology for co-designing with local community groups. The primary goal is to help small, remote areas preserve their heritage, culture, and identity, fostering pride and motivating these communities to envision sustainable futures. The importance of prototyping in participatory design is based on understanding the evolving socio-economic landscape and the need for innovative solutions. Prototyping is not just a phase in the design process; it is a strategic endeavor for risk mitigation and a catalyst for sustainable social change. Within this framework, the article presents three different Prototyping Studios with specific tools that helped researchers in three different locations and contexts to develop and implement the wishes of their local communities.
