How to make a storage space under the deck

If you have a raised deck, you likely have plenty of storage space for tools, gardening supplies, or even unused household goods. Most homeowners do not use under-deck space, and miss out on valuable opportunities to keep indoor and outdoor materials safely tucked away. Building a storage space under your deck is a moderately challenging task that may take you a weekend or two to finish, but the added storage is well worth the effort.

Measure the height and width of the available space under your deck, and decide how large you want your storage area to be. Since your storage box will sit on pavers, its outer height should be 7.5 to 10 cm (3 to 4 inches) shorter than the space between the ground and your deck joists.

Cut 5 by 10 cm (2 by 4 inch) timber sections to form the frame of the storage box. Screw or nail the frame together. Cut pressure-treated particle board or plywood to fit the outer dimensions of the frame. Screw or nail the cut sheets to the outside of the frame, except for the front.

Cut vapour barrier or plastic sheeting to cover the outside of the storage box, and staple it to the particle board or plywood. The sheeting should completely cover the box on all sides, including the top and the bottom. This will help keep the stored contents from becoming wet. It will also help keep moisture from penetrating the wood of the storage box and causing it to rot.

Attach hinges with screws to the front panel of the storage box, and to the side or top edge of the box, depending on the height of the box and what types of items you want to store. Attach a metal latch with screws to the opposite side of the front panel so that the stored contents can be secured. Cover the front panel with vapour barrier or plastic sheeting.

Lay concrete pavers under the deck where the storage box will be positioned. This will help keep the storage box from sinking into the ground. Carefully slide the completed storage box onto the pavers.
