In this fire prone season, we talk with experts about an ancient building technique that might reduce the chance that a building’s going to burn. Unfired, compressed earth blocks are a building material that involves clay, sand and lime. Our guests are architect-engineer Lisa Morey and one of her clients, Matteo Rabescini, who had such a home built in Superior, Colorado after the 2021 Marshall fire. You can read more at Colorado Earth/Nova Terra, Heart of A Building, and Lisa Morey’s substack.
