In addition to the tree house and rocket stove projects already described, there were quite a few other hands-on demonstration projects happening at the Natural Building Colloquium (NBC), and I’ll describe a few of these.
A simple straw bale wall was erected on a prepared concrete foundation; this was directed by Bill Steen with the assistance of Matts Myhrman and many others. This L-shaped wall would immediately serve as a kind of performance stage and could eventually be enclosed for a building.
