I remember that when I attended the Natural Building Colloquium in Kingston, NM in the fall of 2015 there was a fellow named Matt Anderson going around filming and interviewing people. He was part of Earth Lodge Studio, and the result of all this filming was a documentary entitled “What’s a Colloquium?: An Oral History of the Natural Building Movement”
According to his description, “A small band of natural building enthusiasts and outlaws met in a field over 20 years ago at something they called a ‘colloquium’. The movement they created has grown uncontrollably ever since; reviving and innovating ancient building techniques and training thousands in the essential, empowering art of building.”
“Now, as the world faces resource scarcity, increasing climate refugees and 3 billion more people on the way, this tiny backwoods movement prepares for the mainstream. Join these merry pioneers as they celebrate their successes; sharing stories, techniques and wisdom as they brace to meet the needs of a world in crisis.”
