Here's a photo show photo show of a small build at our school, SECMOL in Ladakh, in the Indian Himalayas. It was a natural building course offered by Saurabh Phadke, who I consider an Earth God (not the creator or a "Godman" or anything, just a humble local deity). He's brilliant at teaching natural (earthen) building and about composting toilets, inclusive design for the disabled and others, etc. All round super-cool guy. He's currently in the UK :( and not offering natural building courses in Ladakh or India in the near future, as far as I know.
His website has a lot of cute graphics you can use about composting toilets, natural building, building with mud (adobe bricks, earth bags, rammed earth, wattle and daub), milk glue (casein) including the disabled in design, etc, etc.
Works at a residential alternative high school in the Himalayas SECMOL.org . "Back home" is Cape Cod, E Coast USA.
