Narrow Storage Shelves: Stud Space Cabinet
When you find a good space, mark the perimeter of the opening and use a drywall keyhole saw to cut it out. Measure the opening and subtract 1/4 in. from the height and width to determine the outer dimensions of your behind the door shelves.
For standard 2×4 stud walls with 1/2-in.-thick drywall, build the cabinet frame from 1x4s that measure 3-1/2 in. wide (see illustration). If your walls are different, adjust the depth of the frame accordingly. Then add a 1/4-in. back.We screwed 1/4-in. pegboard to the back so we could hang stuff from pegboard hooks. Add casing that matches the trim in your house. Drill holes into the sides to accept shelf supports. Shelf supports fit in 3mm, 5mm or 1/4-in. holes depending on the style. Install the cabinet by slipping it into the opening, leveling it and nailing through the trim into the studs on each side. Use 6d finish nails placed every 12-in. along both sides.

Measure the distance between the door hinge and the wall and subtract an inch. This is the maximum depth of the shelves. We used 1x4s for the sides, top and shelves. Screw the sides to the top. Then screw three 1×2 hanging strips to the sides: one top and bottom and one centered. Nail metal shelf standards to the sides. Complete the shelves by nailing a 1×2 trim piece to the sides and top. The 1×2 dresses up the shelf unit and keeps the shelves from falling off the shelf clips.
Locate the studs. Drill clearance holes and screw the shelves to the studs with 2-1/2-in. wood screws. Put a rubber bumper on the frame to protect the door. Don’t have an electronic stud finder handy? Learn how to locate studs without a stud finder here.
