Collectif De Boue
Collectif de boue is a nonprofit organization in the field of education and training. Founded by a group of six friends—architects and engineers—we are united by a shared commitment to raising awareness and providing education on the use of natural materials, particularly raw earth, in construction and rehabilitation.
Founded by six friends who are architects and engineers, Collectif de boue emerged from a shared conviction: that natural materials—particularly earth—deserve a central place in modern construction. Our story began with field experiences, collective building workshops, and a desire to reconnect people with low-tech, sustainable practices. Since then, we’ve evolved into a nonprofit hub for education, experimentation, and advocacy, rooted in both technical expertise and community spirit.
Our Mission
Collectif de boue is a nonprofit organization committed to promoting sustainable building practices through the use of natural materials, especially raw earth. We aim to raise awareness, share knowledge, and provide hands-on training to a wide audience—from curious beginners to experienced professionals. Our mission is to make natural construction techniques more accessible and respected within the built environment, contributing to ecological transition, local resource use, and architectural diversity.
What We Do
We educate, train, and support individuals and groups interested in using earth and other natural materials in construction and renovation. Through workshops, on-site projects, and tailored consulting, we provide practical experience and theoretical grounding in earthen architecture. Our work blends pedagogy, craftsmanship, and innovation, creating space for people to discover how local resources can build healthy, sustainable, and beautiful structures.
Key Activities
Our key programs include immersive workshops on raw earth techniques (such as cob, adobe, rammed earth), professional training sessions, and collaborative construction projects. We also host educational talks, exhibitions, and field visits to spread knowledge about biobased materials. By working closely with schools, communities, and construction professionals, we help foster a culture of experimentation and ecological awareness in the built environment.
Upcoming Events
We regularly organize hands-on workshops, open days, and public events throughout the year. These gatherings are opportunities to learn, connect, and practice earthen construction in a supportive and engaging setting. Whether it’s a multi-day building session, a training module for professionals, or a family-friendly demo, our events are open to all levels and designed to inspire. Check our calendar or subscribe to our newsletter for the latest updates.
