Build a Niche Cabinet with Shelves and Doors | DIY Guide 2026

This niche cabinet, built into the space under the stairs adjacent to the kitchen, is perfect for installing pantry shelves and storing recycling bins, all closed off with elaborate doors. The structure and interior of this cabinet are simple, made from raw wood, but for the doors, Cinzia Soriani found original solutions using leftover materials.

Niche Cabinet with Wooden Diamonds

The 20×40 mm slats that support the shelves are fixed to the wall with expansion anchors. For a project like this, having the right home improvement tools on hand makes all the difference.

In the upper part of the niche, on the right side, there is a channel that houses an extension of the electrical system. To access it, you need to shape the corresponding vertical board with a recess large enough to lift the closing profile for any system inspections.

Tools and Materials You'll Need

• Hammer drill for fixing slats to the wall
• 10 mm plywood panels for the doors
• Frame slats with 45° beveled ends
• Leftover plywood strips for decorative rhombus cutouts
• Screws, wood glue, and sandpaper

Building the Cabinet Structure

The doors are made from 10 mm plywood panels enclosed between frame slats, purchased and cut to size with 45° beveled ends. Since they look a bit too simple aesthetically, the front is completed with strips of leftover plywood from cutting the panels, in which some rhombus openings are made.

For the interior, consider adding LED strip lighting to make finding items easier. You might also want to coordinate your new cabinet with kitchen islands and carts for a unified look.

Customizing Your Cabinet Doors

The rhombus pattern is achieved by cutting diamond shapes into the plywood strips before attaching them to the door frames. This creates a beautiful geometric pattern that adds visual interest to what would otherwise be plain cabinet fronts.

Storage Solutions for Your Niche Cabinet

• Use adjustable shelves for flexible storage
• Install pull-out bins for recycling
• Add door-mounted spice racks
• Consider storage benches for additional seating with hidden storage

Frequently Asked Questions

What type of wood should I use for a niche cabinet?

Plywood is an excellent choice for DIY cabinet projects, especially 10 mm multi-layer panels for doors. For the frame, standard lumber works well. You can find quality materials and storage solutions for your workshop at GrandGoldman.

How do I make the rhombus cutouts in the doors?

Mark the diamond shapes on your plywood strips, then use a jigsaw or drill with a hole saw to create the openings. Sand the edges smooth before attaching the strips to the door frames.

Can I add lighting to my niche cabinet?

Absolutely! Battery-operated LED puck lights or strip lights are easy to install and don't require hardwiring. Browse outdoor lighting options for durable, low-voltage choices that work well indoors too.

What's the best way to finish the wood?

For a natural look, apply a clear polyurethane or wax. If you want color, use a primer first, then paint with a semi-gloss finish for easy cleaning. Don't forget to coordinate with your existing wall decor.

How do I ensure the doors are level?

Use adjustable hinges, which allow you to fine-tune the alignment after installation. Check with a spirit level and adjust as needed. For the surrounding area, consider area rugs to define the space.

Final Touches

Once your cabinet is complete, style the top with decorative items or use it as a display area. The built-in look adds value to your home and provides much-needed storage. For additional organizational ideas, check out bookcases and shelving units that complement your new cabinet.

This project is perfect for utilizing awkward spaces under stairs or in alcoves. With basic woodworking skills and the right materials, you can create a custom storage solution that looks like it was professionally installed.
