Using nothing more than discarded pallets and junk that folks tossed away, I was able to build a 12×13 foot off-grid cabin for under $200.00. It is a very solid, warm and cozy constructed building that is powered by solar and wind. The interior is furnished with a tiny wood stove and a custom pallet couch that I made that folds out into a bed.
The unit folds out into a full-size bed!
