The Natural Building Alliance is pleased to announce the 2023 Rocky Mountain Natural Building Conference.  The event will take place from October 20 – 22, 2023 in Boulder, Colorado, USA.

Our organization was founded in Boulder, CO and officially became a 501(c)(3) in 2003.  Our first conference was also in Boulder, and now we’re finally back to where it all began for our 20th anniversary!  Let’s reflect on all we’ve learned and accomplished, celebrate the present, and get excited about the future of natural building!

The event will include approximately 22 classroom-style presentations and round-tables, “mainstage” keynote presentations, and outdoor workshops and demonstrations.  We will also host a tour of sustainable buildings, and there should also be plenty of time to socialize and explore Boulder.

Keynote Presenters

Mattie Mead:

Evolution of Hemp Building Materials

Alison Mears and Jonsara Ruth:

Redefining Sustainable Design with Healthy, Affordable Materials
