Hemp building materials took a prominent place at the Rocky Mountain Natural Building Conference Oct. 20-22. Hemp took the podium along with cob, straw bale, passive house, natural plaster and other natural building technologies, at the Natural Building Alliance's 20th anniversary conference.

A natural builder has constructed a hempcrete wall on his Boulder, CO property hoping the project will be a destination for the hemp-curious who want to see hemp building materials in action.
