I wanted to post this Earthship because the architecture is different. On the backside are the rows of windows like the previous one. All of the silver on the house are the bottoms of aluminum cans. On the tan part are the bottoms of glass bottles. I thought the architecture was very interesting and I really loved it!! My husband thought this looked like the planet Luke Skywalker was from, Tatooine. Had to look that one up! :)
