How to Make a Storage Shed Out of a Wood Cargo Box

Place the reclaimed wood cargo box on a work surface with one end facing you. This end will be the roof for the shed.

Roll out roofing felt over the roof end of the cargo box. Trim the roofing felt to fit the end of the box with an utility knife. Staple the felt to the cargo box with a staple gun equipped with 1/2-inch staples. Space the staples every four to six inches in rows spaced six to eight inches apart.

Lay the corrugated metal roofing sheet over the roofing felt. Cut the metal sheet to fit the roof using metal snips.

Hammer roofing nails through the metal roofing sheet to secure it to the roof. Space the nails every four to six inches in rows spaced six to eight inches apart, making sure you stagger them from the nails for the felt.

Stand the box upright in a work space. Remove the lid from the open side of the box assembly. Lay the lid flat on a work surface. Place the two hinges on one side of the lid. Position one hinge six inches in from each end of the side. Drive the screws included with the hinges through the mounting holes into the lid using a screw gun. This is the door for the storage shed.

Hold the door over the box opening and align the hinges on the corresponding side of the box opening. Fasten it to the box with the screws that were included with a screw gun.

Close the door on the box. Position a shed door handle and latch set over the opposing side of the door and box. Fasten it to the door and side of the box with the screws included with the set using a screw gun.

Apply two coats of wood finish onto the exterior of the storage shed with a natural bristle paintbrush. Allow the finish to dry at least four hours between coats. Wait 24 hours before using the shed.
