Abstract: A concrete floor of a portable storage building is made for one or more storage units with each unit including a floor made through use of a single pair of mold sections or a plurality of pairs of mold sections interconnected for multiple storage units. Each mold section has a raised center and a circumferencial channel with concrete being poured onto the raised center and into the circumferencial channel. Removable exterior mold side walls complete the floor mold. A jack bracket is removably attachable to the floor corners and in turn is engageable with a hydraulic jack for raising and lowering the floor for loading onto the flatbed of a truck for transport to a remote site of use. A chain hoist connected to a top edge of a building wall panel is used to pivot the wall panel to a raised vertical position as the hoist moves on a rail to the vertical plane of the wall panel when raised.
