Walk into almost any suburban home built in the last thirty years and you’ll see it. The "builder grade" special. A fireplace with cabinets on side setups that look like they were slapped together during a lunch break. It’s a classic layout, sure, but most of them feel incredibly dated or just plain awkward. They’re either stuffed with dusty knick-knacks or, worse, they’ve become a graveyard for tangled electronics and DVDs nobody watches anymore.
Honestly, it’s a waste of a room's best focal point.
Getting this right isn't just about picking a wood finish. It's about scale. Most people forget that a fireplace is a heavy visual element. If you flank it with cabinets that are too shallow, the fireplace looks like it’s bulging out of the wall. If the cabinets are too tall without enough "breathing room" at the top, the whole ceiling feels like it’s crashing down on your head. You’ve got to balance the weight. Designers call this visual mass. Basically, if your fireplace is stone, your cabinets need enough "heft" to stand their ground without competing for attention.
The Reality of Designing a Fireplace With Cabinets On Side
There’s a massive difference between "built-ins" and "cabinets." Most homeowners use the terms interchangeably, but they aren't the same. Real built-ins are integrated into the framing of the house. Cabinets are boxes you buy and screw to the wall. If you’re looking at a fireplace with cabinets on side, you’re usually trying to bridge that gap. You want the custom look without the $15,000 contractor bill.

One mistake I see constantly is the "symmetry trap." We’re taught that things need to match. Left side equals right side. But if your fireplace isn't perfectly centered on the wall—which happens more often than you’d think in older homes—forcing symmetrical cabinets makes the room look crooked. In those cases, you’re better off with an asymmetrical layout. Maybe a tall cabinet on the left and a lower bench with floating shelves on the right. It tricks the eye. It makes the "off-center" look seem intentional rather than a mistake.
Let’s talk depth. Standard kitchen cabinets are 24 inches deep. Do not put 24-inch deep cabinets next to a fireplace. You'll lose the fireplace. It’ll look like it’s tucked into a dark alleyway. Stick to 12 or 15 inches. This allows the hearth to remain the star of the show.
Material Choices That Actually Last
People love MDF because it’s cheap and paints well. And look, if you’re doing a solid white finish, MDF is fine. It’s stable. It doesn’t expand and contract like real wood. But if you want that high-end, "I hired an architect" vibe, you need to look at white oak or walnut.
According to Architectural Digest, the trend is moving away from the stark white farmhouse look. We're seeing a return to "moody" dens. Think dark charcoal cabinets with a natural wood mantel. It creates a cocoon effect. If you’re using a gas fireplace, you also have to be paranoid about heat clearance. Real wood cabinets can warp or even char if they’re too close to a high-BTU unit. Check your fireplace manual. Seriously. The "clearance to combustibles" section isn't just a suggestion; it’s a fire code requirement.
Some designers, like Joanna Gaines, popularized the shiplap-and-cabinet combo, but that’s fading. Now, it’s all about texture. Plaster fireplaces flanked by minimalist, handle-less cabinets. It’s cleaner. It’s less busy.
Dealing With the "Black Hole" Problem
The "Black Hole" is what happens when you put a giant TV right above the fireplace and then have dark cabinets on either side. It just becomes a void. To fix this, you need lighting.
- Puck lights: Great for inside glass-front cabinets.
- LED strips: Put these behind the face frames of the shelves. It gives a soft glow.
- Sconces: Mounting a brass or matte black sconce above each cabinet section is the ultimate "expensive" look hack.
Lighting also helps with styling. If you have deep shelves, the back of the shelf is always in shadow. Paint the back of the cabinet a slightly lighter shade than the rest of the unit. It’s a subtle trick that adds depth without being obvious.
Functionality vs. Aesthetics
You’ve got to decide: is this for storage or for show? If it's for storage, you need doors at the bottom. Nobody wants to see your router, your PS5, or your collection of board games with missing lids. The bottom 30 inches should almost always be closed cabinetry. Use the top for open shelving.
There's a specific ratio that works: 1/3 books, 1/3 objects, 1/3 empty space. If you jam every square inch with stuff, your fireplace with cabinets on side will look like a thrift store shelf. Group items in odd numbers. Three vases. One large bowl. Five books stacked horizontally with a small brass object on top. It feels curated.

The Problem with Electronics
Wires are the enemy of a good fireplace setup. If you're building cabinets, you need to plan for "chase" lines. These are holes or PVC pipes hidden behind the drywall that let you run an HDMI cable from the TV above the fireplace down into the cabinet where the cable box or gaming console lives. If you don't do this during the build, you'll end up with those ugly plastic cord covers stuck to your wall. It ruins the whole aesthetic.
Also, consider heat. Electronics hate heat. If your cabinets are tightly sealed and your fireplace is running, those consoles are going to fry. Use "slotted" or "mesh" door inserts if you’re hiding media equipment. It lets the air move.
Real-World Costs and Timelines
If you’re hiring a local carpenter for a custom fireplace with cabinets on side, expect to pay between $3,000 and $8,000 depending on the materials.
- Design Phase: 1 week. Don't rush this. Measure three times.
- Fabrication: 2-4 weeks. Good shops are busy.
- Installation: 1-2 days.
- Painting/Staining: 3 days. Do not let them spray in your house if you can avoid it. Have the shop finish the pieces before they arrive.
You can go the IKEA hack route for under $1,000 using Billy bookcases or Sektion cabinets, but you’ll spend a week of your life
caulking and sanding to make it look "built-in." It’s a trade-off. Time or money.
Common Pitfalls to Avoid
The biggest mistake is the mantel. People often try to wrap the mantel into the cabinets. It’s hard to pull off. Usually, it’s better to let the mantel be its own distinct piece of wood or stone that sits between the cabinets. This creates a "break" that allows for slight variations in the wall's levelness.
Another one? Flooring. If you build cabinets on top of carpet, they will eventually lean as the carpet padding compresses. You have to cut the carpet out and sit the cabinets directly on the subfloor. Then, run your baseboard molding around the bottom of the cabinet to tie it into the room. It’s these small details that separate a DIY project from a professional installation.

Think about the "hearth." If your fireplace has a raised hearth (a stone step), your cabinets should either sit on top of that same level or start above it. Having the cabinets lower than the hearth looks messy. It creates weird little gaps where dust bunnies go to die.
Actionable Steps for Your Project
First, take a photo of your current wall. Print it out. Take a black marker and draw different cabinet heights. You’ll instinctively see what looks "right."
Next, check your power outlets. Most fireplace walls have one outlet right in the middle. Once you put cabinets there, that outlet is gone or buried. You’ll need an electrician to move those outlets into the back of the cabinets before the installation starts.
Decide on your "focal height." If your ceilings are 8 feet, don't go all the way to the ceiling with the cabinets unless you’re prepared to add crown molding to the top. Stopping 12 inches short usually looks better in standard rooms.
Finally, choose your hardware. Knobs are traditional. Long "pulls" are modern. No hardware (push-to-open) is ultra-minimalist. This is the "jewelry" of the room, so don't cheap out on $2 plastic knobs from a big box store. Spend the extra $50 on solid brass or hand-forged iron.
A fireplace with cabinets on side is a permanent furniture piece. It changes how you use the room. It’s where you’ll hang stockings, where you’ll put family photos, and where the eye naturally rests every time you walk in. Take the time to plan the depth and the lighting. Those are the two things that make a wall look "designer" instead of "department store." Focus on the "gap" between the fireplace and the cabinet—keep it tight, keep it clean, and make sure the materials complement rather than compete. Balance the textures. If you have a rough stone fireplace, use smooth, painted cabinets. If the fireplace is a sleek modern tile, go with a grain-heavy wood cabinet. That contrast is what makes the space feel professional.
