After many years of utilizing cultural waste in buildings, I had the opportunity of creating a hew living space for my Mother, she needed to down size, have less steps etc as she gets older. Being the wonderful, experimental, inspirational risk taker that she is, she allowed me to do what I wanted, and use as much junk and recycled stuff as I could.
The house is built around a caravan that had been plastered into place. It's 850sqft. It cost under $7000us to build the whole thing, that includes digger costs to create a courtyard and move trees, the wiring and plumbing. A home without permits or a mortgage!
