More than a decade ago, we envisioned that at some point there would be a need for small (less than 200 sq ft in size), moveable buildings that don't require a permit for use. We then introduced our designs for portable mini storage buildings to fulfill this need.

We created a versatile design that would work anywhere – a building that measures 10 ft. wide x 20 ft. long x 8 ft. high that would accommodate a 6' 6" rollup door. The steel floor is strong enough to support a car. The walls are in the old style 26 gauge painted.


Our latest design makes it possible to stack pre-fabbed walls and roof on the unit floor, band it and ship the structure as a KD (Knock Down) unit to be field assembled. We have manufactured about 450 units for local use in northern California, and with our KD design we can now also ship anywhere in the country.

The base floor is 10 x 20 with 3 types of layout:

1 end entrance, single; next side entrance can be single no partitions, single roll-up door.

Side entrance 2 10 x 10 units with partition and 2 roll-up doors.

Side entrance with 4 5 x 10 units and 4 roll-up doors. All doors have double dead bolts.


Using the base floor we can configure whatever layout you need. One photo shows two units back to back; also note the customer poured concrete to make the unit floor flush with the walkway. Our floors are 8" from grade.

We also make an 8W x 12L x 8H unit in the same KD design for shipment. Single roll-up side or end door layouts are available to meet your needs.

These photos depict typical 2-door 10 x 10 units, which is our best seller.

Our firm also designs and manufactures larger sized mini storage facilities, so if you need help on any type of steel structure let us know and we will be glad to work with you.
