Scott Howard organized a workshop in Dogon Country, Mali, last winter. He built this unique dome with the help of workshop participants and some of the villagers there. The majority of the structure was completed during the two week-long workshop. It is a catenary arc about 16.5 feet tall with a loft. Serving as a library for many villages in the area, it is the first earthbag dome in Mali. Earthen Hand natural building offers a variety of international workshops these days.
I found the above photo in Scott Howard’s article A Wholly Different Way of Building at the Permaculture Research Institute of Australia website. Scott raises a lot of questions in this fascinating article on the best ways to waterproof earthen domes.
