DIY Garage Storage on Wheels

Use a measuring tape to determine the width, depth and height of your garage storage unit. You may use an existing storage unit for reference or simply measure the dimensions of the space where you intend to place your storage unit.

Cut two pieces of 1-inch plywood to the width and depth of your storage unit using a circular saw. These boards are the top and bottom panels. Cut two more pieces of 1-inch plywood to the depth of the unit and the height, minus 2 inches to accommodate the thickness of the top and bottom panels.

Stand all four boards you just cut upright on their longest narrow edges. Arrange the boards in a rectangle shape, sandwiching the side panels between the ends of the top and bottom panels. Drive 2-inch wood screws through the top and bottom panels into the side panels to secure the frame.

Cut a sheet of 1/2-inch plywood to the total width and height dimensions of the storage unit for the back panel. Lay the back panel flat over one open side of the frame you just completed and align the edges. Drive nails from a nail gun through the back panel into the frame below to attach it.

Measure and mark the position for any shelves you want to install inside your storage unit along the side panels in pencil. To determine what interval you should use for your shelves, consider what you plan to store inside the storage unit.

Cut your shelves out of 1/2-inch plywood using the circular saw. Each shelf should be cut to the depth of the storage unit and the width of the cabinet, minus 2 inches to account for the side panels.

Slide the shelves horizontally into place between the side panels where you made the pencil marks. Use a level to ensure that the shelves lay flat. Drive nails from a nail gun through the side and back panels to attach the shelves.

Flip the storage unit upside down so the top panel is flat against the ground. Set four casters on top of the underside of the bottom panel, one in each corner. To make moving your storage unit easier, select casters attached to a swivel plate.

Position the casters so the edges of the swivel plates are between 1/2 and 1 inch from the edges of the bottom panel in each corner. Drive 1-inch wood screws through the holes in the swivel plates into the underside of the bottom plate to secure the wheels in place.

Cut a second sheet of 1/2-inch plywood to the total width and height dimensions of your storage unit for the door. Lay the door flat on the ground and install two metal hinges along the left edge. Position the hinges so they are about 2 inches from the top and bottom corners.

Hold the door against the remaining open side of your storage unit and align the edges. Fold the metal hinges so the half not attached to the door is flat against the left side panel. Screw the hinges into the side panels using 1-inch wood screws.

Paint or stain your completed garage storage unit on wheels. It is wise to also cover your storage unit with a clear varnish or polyurethane to protect the surface from minor wear and water damage.
