Circa 1997-98. This clip is from “A Sampler of Alternative Homes – Approaching Sustainable Architecture” by Hartworks, Inc. Our thanks to them for allowing us to share this clip of the late Mario Bellestri and Pat Bellestri-Martinez talking about building homes with Rammed Earth. The quality of the video is from 1998 when HD was not available. The methods used then are the same methods as what we use today.
