Scott Howard of Earthen Hand Natural Building does it again! This earthbag cabin in Portland, Oregon was “built mostly during a workshop series in summer 2009. We had a lot of fun with building this house.” Click the link to see more pics. I think roundhouses are the simplest earthbag structures to build, and I predict this cabin will spawn a lot of imitations. (I mean that in a good way.)
Visit their 2011 Workshop page if you’re looking for a quality earthbag workshop.
Here’s a good pic of the earthbag cabin under construction.
