Simplify building recessed wooden wall shelves by constructing custom shelving that fits in the spaces between existing wall studs without requiring stud removal. These DIY shelves turn obstacle into opportunity, even in a load-bearing wall. Mark the studs and cut out the sheetrock with a hand tool to avoid damaging electrical wiring and pipes lurking unseen behind the wall.
Use an electronic stud finder to locate/mark left and right edges of studs. To confirm, move in 1/4-inch increments and drive the tip of a small nail into the wallboard to differentiate open space from solid stud behind the wall.
Use a hand-held wallboard saw to cut peep holes to expose wires and pipes. Angle the edges inward at 45 degrees to prevent the cutout from falling inside the wall. Excise the larger panels for each shelf with straight edges.
Cut wood for the shelves and rim of the cabinet using a table saw to rip them to the correct width. Cut them to length with a chop saw or other power saw that facilitates straight cuts.
Align the sides for each shelf unit and custom-position each shelf prior to marking the tops and bottoms of each. Apply glue, clamp the horizontal shelves inside the rim pieces, and secure with a pneumatic nail gun. Add the back.
Test the fit of the shelf unit and position each shelf between the studs. Ensure it is flush with the edge of the sheetrock and temporarily clamp it into position.
Use shims to keep each shelf level and plumb. Drill countersunk pilot holes through the rim and into the studs. Drive wood screws through the pilot holes.
Position paper around the shelf and draw the decorative shelf frame. Remove the paper. Position and tack up 1/4-inch plywood temporarily--it will be removed in the next step. Frames can be fluid or straight or use stock molding.
Apply a coat of spray adhesive to the plywood and position the drawing for the custom frame on the plywood. Remove each section of paper and plywood as a unit and cut along the drawing with a jigsaw to excise the shapes.
Apply dollops of panel adhesive to the backs of the frame components and correctly position them around the decorative shelf. Secure them with nails driven through the frame into the wall behind.
Add dollops of panel adhesive to the back of the corkboard and position it inside the shelving frame after relocating outlets and patching peep holes as necessary. Add the last piece of trim to cover the edges.
