I am looking for manufacturers of small pre-fab houses made of aluminum preferrably. I have a handicapped client who would be using it. It would have to be flat, open floor plan, with a roll in bath for wheel chair. Perhaps something that could be put on a slab. We live in Hawaii where termites are a scourge and the weather would welcome walls of sliding glass doors, with a large over hanging roof for shade from sun and drizzle.
