I’m russian architect and earthbag builder. Recently I’ve made an earthbag village development project that won prise at russian architectural competition. I hope you’ll enjoy its content here: http://izproject.ru/2047-2/ (text is in Russian but there are lots of interesting drawings and photos)
“In August 2008 we saw ourselves back on the plane to Siberia. This was our second trip as a group of builders and teachers to this far and exotic place we now consider our most remote home away from home. Paul Koppana (Crestone, CO), Cindy Smith (Durango, CO) and myself, Jeff Ruppert (McKinleyville, CA) were much more comfortable this time traveling half-way around the globe having made a trip for the same reasons back in the summer of 2005.
