That’s not a bad looking house, and with a little tweaking, that modern exterior could be given a Craftsman look!
Geez, those are a lot nicer than the ones I’ve lived in. In Africa I had a 20-footer for an office...we had four configured with a roof over them. The roofs always seemed to leak until we built truses and roofed them. I lived in a 40-footer with bathroom in a maintenance camp on a project in the Andes of Argentina. It was insulated, but at -40F it was always cold.
They work very well and have tremendous utility.
