How to Build a Custom Built-In Using Stock Shelving

Custom built-in shelving can transform a room and make it feel more cohesive and put-together. While custom cabinetry can be expensive, you can create a high-end built-in look using standard stock shelves and other inexpensive materials. With a bit of planning and DIY work, you can build beautiful built-ins tailored to your unique space.

Choose an Area for the Built-In

The first step is to decide where to install your custom built-in shelving unit. Think about areas that could use some extra storage or display space. Some popular locations include:

Living room – Built-ins surrounding a fireplace or TV create visual interest and keep clutter hidden. Floor-to-ceiling shelving makes a statement.
Dining room – Open shelving to display dishes, glassware and decorative items free up cabinet space.
Home office – Built-in desk, shelving and cabinetry for an organized workspace.
Kitchen – Spice racks, open shelves for cookbooks, and cabinetry for storage around a kitchen window or blank wall.
Bedroom – Built-ins make great bookcases or display units for personal items. Floor-to-ceiling units maximize space.
Bathroom – Extra storage for towels and toiletries near sinks or tubs.

Consider the size of the area and how you want to use the space. Measure to determine what size shelving unit will fit. Also check for potential issues like radiators, electrical outlets or venting to work around.

Choose a Stock Shelving System

Once you’ve selected the location, decide on standard stock shelving to form the base of your built-in system. Stock shelving is affordable and comes in a wide variety of sizes, finishes and load capacities. Some popular options include:

Wire Shelving: Very inexpensive and adjustable, but exposed wires aren’t very attractive for built-ins. Best used only on closets or pantries.
Wood Shelves: Offer the look of custom millwork at a fraction of the cost. Solid wood or veneer shelves come in oak, maple and other finishes to match your decor. Durable for books and heavier items.
Chrome Wire: Sleek metal wire shelves in chrome or black finish for a modern, industrial look. Glass or wood shelving can be added on top. Sturdy but usually more expensive than basic wire or wood.
Metal Brackets with Wood: Strong metal brackets securely hold wall-mounted wood shelves and are concealed by the shelf above. Allows for shelving only where needed.

Consider finish, depth and weight capacity needed. Measure the area to determine what length shelves you’ll need. Plan any fixed vertical supports needed to hold longer spans.

Build a Frame to Enclose the Shelving

Once you have the core shelving picked out, decide on materials to build an enclosing frame around it. This frame will give your shelving a custom look.

Frame Options:

Plywood panels – Affordable and can be cut to size. Paint or finish to match decor. Can be edged with trim pieces.
MDF – Smoother than plywood if you’ll be painting. Heavy so consider thickness needed.
Wood boards – 1×3, 1x4s and other dimensional boards can face frame the unit. Choose pine, poplar or other inexpensive wood and paint/stain to desired finish.
Trim – Crown molding, baseboard, door/window casing and other trim adds detail. Paint or stain trim to match or contrast.
Drywall – Finish framing gaps with drywall to give a seamless built-in look. Tape, mud and sand for smooth finish to paint.

Cut frame pieces to fit tightly around the shelving unit. Secure into studs in wall and/or floor. Add trim details as desired.

Finish and Install the Built-In Shelving

Adding moldings, panels and finishing touches will complete your custom built-in:

Pre-finish boards – Stain, paint or finish all frame boards before installing for easiest finishing.
Fill gaps – Use wood filler to fill any cracks or gaps for a seamless look after painting.
Install shelving – Set shelving into framed opening. Secure firmly into framing. Follow manufacturer instructions.
Hardware – Add drawer pulls or knobs if including drawers or cabinets. Undermount slides give a sleek look.
Doors – Hang doors to conceal some areas. Shaker style doors complement most built-ins.
Trim out – Install any additional trim like crown molding, light rails or baseboard.
Finish touches – Add glass cabinet doors, bottle racks, media storage or other custom elements.
Lighting – Install discreet lighting on upper rails or inside cabinets to highlight displays.

Taking time to properly construct, finish and install the total unit will make it look like high-end custom cabinetry for a fraction of the cost!

Design and Measure the Built-In Shelving Area

Careful planning is crucial when designing a built-in shelving unit. Follow these steps:

Sketch designs to scale – Make overhead and front views to visualize finished look.
Take measurements – Note all dimensions of installation area including ceiling height.
Map electrical – Mark outlet and switch locations to work around.
Plan shelving layout – Decide shelf sizes, spacing and placement. Mix open and closed storage.
Select hardware – Choose drawer slides, hinges and handles based on your plans.
Pick materials – Order shelving, boards and trim needed per your plan measurements.
Check codes – Ensure unit meets any clearance or spacing requirements per local regulations.

Having detailed plans and measurements ensures everything fits together properly for a professional built-in look. Taking the time to design it right will make the installation go smoothly.

How to Install Stock Shelving as Built-Ins

Fasten shelving, cabinets and drawers securely per manufacturer instructions.
Make sure all units are level and plumb. Shim if necessary.
Add hardware like drawer slides, hinges and knobs/pulls.
Install additional functional elements like wine glass holders, bottle racks, etc.

Complete Built-In Frame

Install trim boards around unit and at seams for a finished look.
Caulk around edges and seams; let dry completely.
Reinstall switch plates and baseboards removed previously.
Doors can be added last after the unit is completely secured.

With careful planning and execution, stock components can create stunning custom built-in shelving!

Choosing Materials and Hardware for Built-In Shelving

The materials and hardware you select will determine the look, quality and functionality of your finished built-in shelving unit. Consider these factors when choosing components:

Shelving

The core shelves that form the base of the built-in should be:

Sturdy enough for intended use (books, decor, etc.)
Adjustable if possible for versatile storage
Finished to complement room decor (stain, paint, natural wood)
Right depth for items to be stored; 10-12” common

Popular shelving unit materials:

Solid wood shelves or plywood panels with veneer surface
Tempered glass shelves for a contemporary look
Perforated metal shelves to create an industrial vibe

Frame

Boards used to face frame the unit should be:

3/4” plywood for maximum stability

Trim

Trim adds shape and covers seams:

Baseboard, crown molding, door/window casing moldings
Corner trim blocks for finishing edges
Rosettes, corbels and other decorative accents

Match trim style to the room’s existing architectural details.

Hardware

Hardware enables cabinets, drawers, and adjustable shelves:

Undermount drawer slides for smooth, invisible operation
Soft-closing hinges so doors close silently
