Join us for a workshop, led by Rowena Bashforth and jointly delivered by the WeCanMake team, Material Cultures and the RIOT Lab EPFL, exploring both the theory and hands-on practice of working with lime.
THE WORKSHOP: This workshop offers an introduction to the traditional and contemporary use of lime in building, with a focus on rendering directly onto straw bale walls. Participants will learn about the properties of lime, its role in breathable wall systems, and how it supports healthy, low-carbon retrofits. Through demonstrations and hands-on sessions, you'll gain experience preparing lime mixes, applying base and finish coats, and working with different tools and techniques. The first two days (13-14 October) will include site orientation, talks, and guided practical sessions. Participants are then welcome to stay for an additional three build days (15-17 October) to deepen their skills and contribute to a live project.
