Thanks @ackza! This was a fun post because I am so excited about building this. The plans r in my head n now will be on the land. The earthship homes were my first interest in a sustainable home I could build myself. I have learned more about them and I don't like the idea of using old tires for the walls. They can smell in the hot sun, giving off toxic fumes. They have voc that u breathe in. I would like to visit the earthship village in New Mexico.
