Natural Building Network is a not-for-profit membership association promoting natural building principles, materials and practitioners worldwide. We support ecological regeneration, social justice, the building of community and economic opportunity, and the recognition of indigenous wisdom as essential in creating healthy, beautiful, and spiritually-uplifting habitation for everyone.

Founded in 2005, our charter members include pioneers in the Natural Building movement and non-professionals with a passion for ecologically sound and fundamentally safe ways of living. Our members come from all walks of life but share a care for our planet. We are teachers, artists, doctors, community leaders, professional natural builders, owner-builders, engineers, architects, designers, contractors, international development workers, and more. We share an interest in seeing Natural Building become a safe, beautiful, renewable and common  sight in our modern landscape.
