Step 1: Cut the Plywood

Using a circular saw, cut three pieces of 3/4" birch plywood, each 12" x 6’. Cut two end pieces to 12" square. Cut shelves 10.5" x 11.25". Cut two pieces of 1" x 2" trim to a length of 73.5", making sure to miter the ends. Cut two pieces 1" x 2" trim to a length of 13.5", also mitering the ends.

Step 2: Build the Shelf Unit

Assemble the box out of the three long panels and two end panels. Using simple butt joints, nail the pieces together to form the box. Attach pre-cut trim pieces to front of box.

Step 3: Attach the Shelves

Measure and mark the position of the shelves. Run a thin bead of wood glue along the marks inside of the shelving unit. Slide the shelves in place and secure with nails. Use a framing square to make sure the shelves are square and level.

Step 4: Sand the Unit

Sand the wood smooth using an orbital sander and then fill all the nail holes with wood putty. Prime and paint if desired.

Step 5: Mount the Shelving Unit

Position the finished shelving unit in the closet and mark its desired location on the wall. Remove the shelving unit and use a stud finder to locate the wall studs. Attach the shelving unit to closet wall by driving screws through the box and into the studs. Insert the shims behind the box as needed to level.
