How to Make Built-In DIY Shelves For the Bedroom

Cut plywood sheets into strips

Mark the width of the cut on both ends of the sheet. Align the ends of the straightedge guide with the marks and clamp the ends. Make sure to place the guide on the ‘keeper’ side of the marks. Run the saw along the guide to complete the cut.

Cut the strips to length

A crosscut guide allows you to make perfectly square cuts exactly where you want them. Mark the cut location and line up the guide. Clamp the guide and make the cut. Make sure to keep the saw bed tight to the guide fence as you make the cut.

Mark the curved brackets

Use the dimensions from the PDF and cut list to mark the shape of the bracket on the 1×10 board. Drill a nail hole and pencil hole in a scrap of wood to use as a compass. Cut out the shape with a jigsaw. Sand the curve until it’s smooth. Then use this bracket as a template to mark the three remaining brackets.

Cut the brackets (N) from a solid 1×10 board. Using the project plan as a guide, mark the shape on the 1×10 board. This photo shows how to draw the curve. Cut out the brackets with a jigsaw. Then sand the curves to get rid of saw marks and smooth them out. Use the first bracket as a pattern to mark the rest.

Apply edge banding with an iron

Cut iron-on edge banding about an inch longer than you need. Center the strip on the edge of the plywood and iron it on. Keep the iron moving. As soon as you’re done applying heat, rub over the entire surface with a small chunk of wood to ensure good adhesion. Trim off the overhanging ends with a sharp utility knife.

Trim edge banding

Starting at one end, slide the special edge-band trimming tool along the edge banding to slice off any overhanging veneer. Carefully sand the edge to remove any trace of overhanging veneer.

You only need to apply edge banding to the edges that show. Parts A, F, L, M and E require edge banding on one end as well as the long side.

Immediately after you iron on the edge banding, slide a small block of wood from end to end while pressing down firmly. This will ensure good adhesion. Trim off the overhanging ends with a sharp utility knife. Then trim off the overhanging veneer from the edges.

Finish up by carefully sanding the edges with 120-grit sandpaper to create a perfectly flush, smooth edge.

Hold the box parts square

It’s a lot easier to assemble the pieces if you have a right-angle jig to hold them steady while you drill pilot holes and drive screws. Make the jig out of scraps of plywood. Then line up the parts and clamp them to the jig.

Assemble shelves with screws

For easy assembly, join the sides to the tops and bottoms with trimhead screws. Drill 1/8-in. pilot holes first. Then drive the screws until the heads are slightly recessed. After the first coat of finish, fill the screw head recesses with soft wood putty to match the stain and cover with a final coat of finish.

With the parts cut and edge-banded, it’s time to start building.This photo shows a simple right-angle jig you can build to help hold the parts in position as you screw them together.

Make light pencil lines across parts A and F to indicate the centerline of parts B and G to help you place the screws accurately. Drill 1/8-in. pilot holes 2 in. from each end and in the center to guide the screws. Then drive the 2-in. trim-head screws (60) until they’re slightly recessed. Don’t worry if the shelves are still a little wobbly. They’ll be held firmly in position when you mount them to the wall. While you’re at it, screw the pairs of brackets (N) to the cleats (E).

Drill holes for shelf pins

To avoid mix-ups, drill the shelf pin holes after assembling the shelves. Build mirror-image drill guides from 1/4-in. pegboard with 1×2 stops. Drill a hole in a block of wood to use as a drill-bit depth stop.

For adjustable-height shelves, we drilled a series of 1/4-in. holes to accept shelf pins. If you don’t think you’ll adjust the height of the shelves, just drill four holes at each shelf location. It’s easier to make sure the holes are aligned if you drill them after you’ve assembled the shelves.

We positioned the shelf pin holes so that a shelf can be centered in the middle unit, and approximately evenly spaced in the two outside units. We also offset the holes in the two center dividers (H) so the pins don’t run into each other. Most of the holes are 1 in. from the front and back edges. The holes in the center of the middle unit are 1-1/2 in. from the front and back edges.

The photo here shows how to use a 1/4-in. pegboard jig as a guide for drilling the shelf pin holes. To avoid confusion, we made mirror-image jigs to use on the right and left sides of each upright. Make an arrow pointing up to keep the guide properly oriented and mark the holes you intend to drill. Cut a 3/4-in. square scrap of wood or dowel and drill a hole in it to use as a drill stop.

Practice on a scrap to get the correct hole depth. Drill all the holes in the taller outside units first. Then cut off the pegboard guides and use them for the middle shelves. Reposition the stop to drill the offset holes for the center shelves.

Mount the center shelf

Level the ledger (L) and attach it to the wall studs with trim screws. Rest the center shelf unit on the ledger, aligning the sides with the ends of the ledger. Make sure the sides are plumb. Then drive screws through the hanging cleat into the studs to hold the shelf in place. Drive trim-head screws down through the bottom shelf into the ledger.

Add the end nuts

Align the top of the outside shelf unit with the top of the center shelf unit. Make sure the top is level. Then drive screws through the hanging cleat into wall studs to support it. Center the decorative brackets under the shelf and attach them to the wall studs with screws.

We stained and varnished the shelf units and the moldings that go on top before installing them. Whether you’re staining or painting the shelves, plan to apply a final coat of finish after they’re installed and the moldings are put on. That will allow you to fill the nail and screw head holes and cover them with a coat of paint or varnish.

Install the Units

To get ready for the installation, mark the center of the bed with a piece of masking tape. If you have a headboard, mark the height. Then move the bed out of the way.

Use a stud finder or some other method to locate the studs and mark them with tape. Then determine how high you want the center shelves to be. We chose to position the shelves a few inches above the headboard, which in our case was 60 in. above the floor. This is a good height to allow headroom for sitting up in most beds. Draw a level pencil line at your chosen height.

Align the plywood ledger (L) with the mark, center it on the bed location and fasten it to the studs with trim-head screws. Now it’s easy to install the center shelf unit by resting it on the cleat. Before you screw the center shelf unit to the studs , make sure the ends are lined up with the plywood ledger and the sides are perfectly plumb.

Next install the two outside shelf units by lining up the tops and screwing through the hanging strip (D) into the studs. Connect the shelf units with 8 1-1/4-in. trim-head screws.

Snug the brackets (N) up to the bottom of the outside shelves and screw through the hanging cleat (E) into the studs.

Install the cove molding

Finish up by installing the cap and cove molding to the tops of the cabinets. Miter the inside and outside corners. We used a finish nail gun, but you can also drill pilot holes and attach the moldings with trim nails. Fill the nail holes with soft putty to match the stain.

The final step is to cut and nail on the 1×3 cap and 2-in. cove molding that fits under it. Start by cutting the cap pieces and nailing them onto the top of the shelves. We used a finish nailer. If you’re hand-nailing the cap and moldings, drill pilot holes for the finish nails to avoid splitting the cap or moldings. Hold the back edge of the 1×3 cap flush to the back of the plywood and cut 45-degree miters at the corners.

Install the cove molding (Q) after the cap is done. Miter the outside corners. Since the inside corners will be perfectly square, you should be able to miter them rather than cope them. But you can use whichever method you prefer. Take your time and expect to spend several hours on this part of the project. There are a lot of little pieces to cut. Keep your fingers a safe distance from the blade by cutting the small pieces of cove molding from long lengths.

When you’re done mounting the shelves and installing the moldings, nail and screw head holes will be showing. If your shelves are stained, fill the holes with soft wood putty to match. You can even blend colors to get a closer match. For painted shelves, fill the holes with lightweight spackle, let it dry and sand it. Then apply the final coat of finish.
