It depends on size,
materials, and finish.

There's no sticker price for custom built-ins, and any number posted online would mislead you — a single pantry wall, a built-in library, a mudroom system, and a window seat are all different jobs. What every honest quote comes down to is three things: how big it is, what it's made of, and how the finish is executed. Everything else — design, hardware spec, installation complexity — is a smaller variable that lives inside those three.

So instead of guessing at a number, this guide walks through what actually moves the price, so you can read your own project before we ever talk.

What moves the number,
type by type.

Every project is priced individually based on a site visit and a written proposal. Here's what pushes a project toward the simpler end or the more involved end, type by type.

Custom Pantry Cabinets

A typical custom pantry — a single tall cabinet run, floor to ceiling, fitted to an existing alcove or installed against a kitchen wall. Paint-grade construction, soft-close hardware, a mix of adjustable shelves and pull-outs. The simplest is a 24–36" wide unit; the most involved is a multi-bay run with inset doors, integrated cubbies, and more complex internal organization.

Built-in Library / Bookshelf Wall

Floor-to-ceiling shelving with cabinet bases, crown details, and (sometimes) integrated lighting. Cost scales with linear footage of wall, depth, and whether doors are involved. A modest 8' wide library with open shelving is the simplest; a 12–16' wall with paneled cabinet bases, inset doors, and trim that matches the existing house is the most involved.

Mudroom Storage / Lockers

A mudroom system with lockers, bench seating, lift-lid storage, hooks, and cubbies — fitted to your entry wall. Cost tracks with width and depth of the run, plus whether there's drawer storage, integrated coat-rod sections, or upper cabinet shelving.

Window Seats with Storage

An upholstered bench with cabinet storage built into the base, scribed to a bay window or reading nook. Cost varies with the complexity of the surround — a simple bench in a flat-wall opening is the least involved; a piece that wraps a bay window with side cabinetry, paneled returns, and crown details is the most.

Three real cost levers.
Everything else is noise.

Material. Cabinet-grade plywood with hardwood face frames is the standard for built-ins worth keeping. Paint-grade work uses primed MDF for the door panels — flatter, holds finish better, doesn't crack at the joints over time. Solid hardwood throughout (stain-grade) costs more. Specialty species — walnut, white oak, cherry — add real dollars compared to poplar or maple.

Labor. Every custom built-in is built by hand. Face-frame construction with inset doors takes more time than frameless overlay. Hand-fit reveals, scribed installations, and trim that matches existing house carpentry all take time. Time is the dominant cost in any honest custom build — material is usually less than half the total.

Finish. Painted lacquer over primed wood is the cleanest finish and the most labor-intensive. Stain-and-clear-coat is faster but only works on stain-grade material. Custom color matching, multi-tone work, glazed finishes — these add a meaningful percentage to the finish cost.

And when
it isn't.

Custom is worth it when: your space has odd dimensions a stock cabinet won't fit; you're matching existing trim or millwork in an older home; you want the piece to last 20+ years and read as original to the house; you have a specific storage problem stock cabinetry can't solve.

Stock or IKEA wins when: the space is standard dimensions a 24"/30"/36" cabinet fits cleanly; budget is fixed and lower than a custom build costs; you're planning to move in under five years; the goal is "fill this wall" rather than "build a piece that belongs here."

The honest read: most kitchen pantry and laundry storage problems can be solved adequately by an off-the-shelf IKEA Sektion order. It won't read as original to the room, the materials won't last the life of the house, and it'll look like an IKEA pantry — but it'll function. That's a legitimate choice.

Custom is for the projects where "functions" isn't the goal — where the piece needs to fit the room, match the house, and last longer than the kitchen around it.

Inquiry. Site visit.
Fixed-price proposal.

Pricing is never quoted off a phone call or a Google form. Every project gets a site visit, dimensions, and a written proposal with a fixed price before any deposit is taken. That's the only honest way to do this — measurements, materials, and finish choices drive the number, and none of those are known until the site visit happens.
