Tiny office/ house/ or food cart

I have been building this tiny office as a mobile office for my construction company. It is currently unfinished, but included in the sale price is the installation of horizontal tongue and groove "beetle kill" siding and a galvanized roof. The entire structure has been built with screws and glue. The floor is insulated with ridged foam. There is a 2'x8' deck on the rear that has trex decking. There are two Jeldwen slider windows and a craftsman style fiberglass rear door.
