Below is the first draft of what I plan to do with the 2 40 ft containers, (pending of course, my discussions with the county planning department).
Draft 01
The scale is 1 ft / 1 dot. The wall insulation/framing will probably be less than 1 foot as shown. The dark lines reflect the wall sections left from the original container. Note this is only a one bedroom design since I am assuming I have the 5-th wheel trailer for a guest house. Your inputs are welcome.
