This is the castle compound, one of the grandfathers of the Earthships. A three story building made from thousands of drink cans (probably beer!). The G2 (global model) site is almost done. There is still a lot of indoor plaster finishes to do, an that's what i've been doing today. With the plaster finish, were adding a colour dye to the cement mix, and using extra fine sand. The bottle walls have been very interesting to finish, and i'll post some photos of that tomorrow!
