Michael Reynolds is the founder of these beautiful and functional dwellings that are usually set into the ground.
Martin Freney owns the first council approved Earthship in Adelaide Australia. See both pictures below. See his site at http://earthship.com/blogs/author/mfreney/
They are designed specifically for each particular region. These dwellings are self-sustaining and require very little maintenance to keep running. Modest in size but more than adequate for comfortable living.
Virtually indestructible and made from waste materials such as tyres and plastic that do not degrade these dwellings will last many years with very little maintenance. Finishing's and size are dependent on what one can afford.
