Have a 20’. Cut two windows and a regular entry door into it, a partition wall that creates 8’ of storage area accessible by the standard doors, and an office in the other 12’ with the windows and door. LED lights and some receptacles, lvt flooring, 2x2 studs, insulation and plywood on the sidewalls and ceiling.
$2,000 for the container, Probably another $2,000 in the work.
Pretty handy. It’s been on a job for 18mos, bout to move it to another job where it will be for 24 mos.
