Odd homes
 

We got everything from converted missile silos to converted airplanes. Pretty odd and definitely a bit entertaining. :)

I love the treehouse. It is really beautiful. I remember reading National Geographic World in the 70's as a kid. They often showed various earth ships.

that's cool.
When i was a kid, my uncle had a big farm nearby and he had a smaller metal grain bin that he didn't use anymore. I wanted to use it for a playhouse for the longest time, but i was too little to go about moving it and stuff.

I'd like to see someone convert one of those tall verticle concrete grain silos into a house :D.
