G'day from Australia. I'm a residential builder in NSW. I've been fascinated in earthen homes for years, but am yet to build my own. I recently saw a simple earthen home, with round walls and thatched roof in a picture from an Eastern Country. I wondered how this type of build might offer healthy, sustainable home options for people in our part of the world. I have land but I am time poor at the moment. When I get some time, I want to start experimenting with small scale models before constructing something larger.
