Google searches havent produced much help to me.

I’m trying to be REALLY creative and come up with the absolutely cheapest way to build my own functional house 10′ by 12′ and bigger.

Does anyone have any ideas? No idea too small! Has anyone used Cob, cinder blocks, or anything like this to build a home, seen someone who had, or found any website with things about this? I don’t want to pay any more than $1000 to start with. Also I’m in Texas, a dry climate.
Thanks William B. Thats awesome!
