The container dilemma and redesign!
So far I've heard whatever is used has to have fireproof floors and walls and not be considered a permanent structure. It is also understood that the container idea is fixed!
So, assuming the container is so designed to be supported on the four corners and has a metal floor lined with plywood and no idea of the walls other than metal on the outside.
Locate the site. Install a piling for each corner. Cut out the floor area for the press and pour a cement foundation for it. Skin the floor using concrete and put the proper slopes and drains on it. [Not very hard to do and the container should be able to support this with no problem.. Just use ordinary high strength concrete with no rebar or wire mesh for cost purposes. Cut out the doors and other access points as required and use the cutouts for fabricating the new doors. Have the doors open out wards so they do not constrict inside space. Build dirt ramps for the access doors. Cheap.
Install several ventilating fans high up one at each end. Bathroom fan would work.Install one pressurizing fan at floor level in the center of the container. Again bathroom fan. If the walls require fireproofing use a stucco or cement slap on and trowel smooth product. Don't worry about insulation.
Getting services in should be no problem as torches work on metal quite well.
Keep it as simple as possible and all will work out!
