The space behind a door is a storage spot that’s often overlooked. Build a set of shallow shelves and mount it to the wall behind your laundry room door. The materials are inexpensive. 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.
