The Rocky Mountain Natural Building Conference in Bozeman last week was a huge success! From September 18-20, over 160 participants gathered at the historic Emerson Center to learn, share, and connect.
With more than 20 presenters and three fantastic keynote addresses, we dove deep into the world of natural building materials and methods. The event was a testament to the power of collaboration and community, proving that learning can be both informative and incredibly fun.
A huge thank you to everyone who attended and presented—your energy and passion made this a truly memorable event. The connections made and knowledge shared will undoubtedly help build a more sustainable future, one natural building at a time.
