Custom cabinetry changes everything. You walk into a room, and instead of a TV stand that looks like it’s just hovering awkwardly against a beige wall, you see a seamless integration of wood, light, and architecture. It feels permanent. It feels expensive. But honestly? Most people mess up built ins for living room projects because they treat them like furniture rather than part of the house's skeletal system.
If you’re just looking for a place to put your books, buy a bookshelf. Built-ins are different. They are about correcting a room's proportions. They can make a low ceiling look soaring or hide that weird bump in the wall where the HVAC ducting runs. Sarah Susanka, the architect who basically started the "Not So Big House" movement, has spent years talking about how these permanent fixtures create "shelter within shelter." It’s that cozy, anchored feeling you can't get from a flat-pack unit from a big-box store.
The Expensive Mistake of Symmetry
We’ve been conditioned to think everything needs to be a mirror image. You have a fireplace in the middle, so you put identical cabinets on both sides. Stop. It's boring.
Designers like Amber Lewis have been leaning heavily into asymmetrical designs lately. Maybe one side is a floor-to-ceiling library wall with a rolling ladder, while the other side features a lower bench seat with a massive piece of art above it. This creates visual tension. It makes the eye move around the room. If everything is perfectly symmetrical, the eye just hits the center and stops. Boring.
Also, think about the depth. Standard lower cabinets are 24 inches deep. If you run those all the way to the ceiling, you’re going to feel like you’re sitting in a tunnel. Professional trim carpenters often stagger the depths—maybe 20 inches for the base and only 12 or 14 inches for the upper shelving. It opens up the "head space" of the room. It breathes.

Materials: Don't Get Scammed by "Solid Wood"
There is a massive misconception that "real quality" means 100% solid wood. If a contractor tells you they are building your built ins for living room entirely out of solid oak or maple planks, they are either lying or giving you a product that will warp within two years.
Wood moves. It shrinks and expands with humidity.
For the box construction (the "carcass"), you actually want high-quality Cabinet Grade Plywood or even MDF (Medium Density Fiberboard) if you’re painting them. MDF is incredibly stable. It doesn't have a grain that will telegraph through your paint job. Save the solid wood for the face frames, the door stiles, and the nosing of the shelves. This is how the pros at companies like California Closets or high-end local shops actually do it. It’s not about cutting corners; it’s about engineering for longevity.
Lighting is the Secret Sauce
You can spend $15,000 on cabinetry, but if it's dark, it looks like a black hole. Most people forget the wiring until the units are already bolted to the studs. Then you're stuck with those battery-powered puck lights that look cheap and die in three days.
You need hardwired LED tape.
Hide it behind a lip at the front of the shelf, not the back. If you put the light at the back, you’re just silhouetting your stuff. If you put it at the front, you’re washing the spines of your books and the textures of your vases in light. It feels like a gallery. And for the love of everything, put them on a dimmer. There is nothing worse than a "stadium lighting" vibe when you're trying to watch a movie on a Tuesday night.
Dealing with the "TV Problem"
Let’s be real. The living room is usually a theater.
The biggest trend right now is the "hidden" TV. You've seen the Samsung Frame, which is great, but cabinet makers are getting clever with pocket doors or sliding art panels. Think about the future, though. If you build a tight "niche" for a 55-inch TV today, and in five years you want a 75-inch, you are basically ripping out your woodwork.
Build the opening larger than you think you need. Use a dark backing—maybe a charcoal grey or a deep navy—inside the TV cavity. This helps the screen "disappear" when it’s off, even if you don't have a fancy art-mode television.
The Cost Reality
It’s pricey. Let’s not sugarcoat it.
A basic, paint-grade built-in using birch plywood might run you $500 to $1,000 per linear foot. If you start adding white oak, rift-sawn details, integrated lighting, and soft-close hardware (which is non-negotiable, by the way), you can easily hit $2,000 per linear foot.

Why the price jump? Labor.
Installing built ins for living room isn't just about building boxes. It’s about scribing. Your house isn't square. No house is. A master carpenter will spend hours "scribing" the wood—shaving off tiny slivers so the cabinet fits perfectly against your wonky, crooked walls. That's what you're paying for. The lack of gaps. The seamless look.
Beyond Books: Specialized Functions
What do you actually do in your living room?
If you have kids, the bottom 20 inches of your built-ins should be closed storage with heavy-duty hinges. This is the "toy graveyard." You need to be able to shove a mountain of Lego and plastic dinosaurs in there and shut the door.
If you’re a collector, you need glass. Dust is the enemy of a good display. But don't just do standard glass. Look into "seeded" glass or "fluted" glass for a bit of texture. It obscures the clutter while still letting the light through.
And don't forget the outlets.
Hide them in the back of a shelf for a charging station. Put one at the base for a vacuum or a lamp. You should never see a cord dangling down the front of a custom built-in. It ruins the whole "custom" illusion immediately.
Small Space Hacks
If your living room is tiny, don't shy away from built-ins. People think they take up space, but they actually save it. By utilizing the vertical "dead" space above a sofa or around a window, you eliminate the need for three or four separate pieces of furniture.
A "window seat" built-in is the classic example. It provides seating and storage without taking up a single square inch of the actual floor "traffic" area. It makes a room feel intentional rather than cramped.
Practical Next Steps for Your Project
Before you call a contractor or head to the lumber yard, do these three things:
- Inventory Your Stuff: Measure your tallest book. Measure your TV. Measure that weirdly large vase you inherited. Make sure your shelf heights are actually functional for what you own.
- Locate Your Vents: Look at the floor and walls. If your built-in covers a HVAC vent, you need to build a "toe kick" vent to redirect that air. Do not just cover it up; you'll kill your furnace and grow mold.
- Tape it Out: Use blue painter's tape on your wall to mark exactly where the cabinets will go. Leave it there for three days. Walk around it. See if it makes the room feel too small or if it blocks the natural flow of traffic.
Building permanent cabinetry is a commitment to the house. It's an investment that usually sees a high return because buyers love the "finished" look of a home with architectural character. Just remember: measure twice, think about your lighting, and never, ever settle for cheap hinges. Your future self, tired of hearing doors slam or seeing sagging shelves, will thank you.
