Window seats and bay window benches in Lynn, MA are shaped by the room rather than by a drawing, so Custom Cabinets Lynn makes a full-size pattern of your bay before anything gets cut. A fitted seat with storage under the lid runs $2,500 to $3,500. A smaller nook under a standard window runs $500 to $4,000, and a full-depth built-in daybed runs $1,000 to $8,000. Our cost guide sets those beside the rest of the built-in work in a house.
We measure the two side walls of your bay separately, at the sill and again down at the floor. In a house this age those four numbers rarely agree. A seat cut square to any one of them leaves a gap you can see from across the room.
We also need to know what is under your window now. In most of these rooms it is a radiator. A seat that closes one in stops the room heating, so the front takes a grille and the back stays open.
The third thing we look at is your floor. A bay usually sticks out past the foundation, so the floor inside it has often dropped further than the rest of the room. We build the seat to that floor rather than to a level line it will never meet.
Where the cabinetry is going
A seat across a bay
We make a pattern of your bay in one piece rather than measuring it. The two side walls come back at their own angles, and a pattern carries that where a tape measure loses it. What comes out of the shop has four different angles. It lands tight against both walls without a cover strip showing anywhere along the front.
A lift-up lid over the storage
We hang your lid on a Blum lift-up hinge where the seat is deep. A solid lid across a bay is heavy enough to hurt somebody on the way down, and a cheap friction stay will not hold one for long. Where the seat is shallow we put drawers underneath instead. A drawer you can open with the cushions still on gets used, and a lid you have to clear first does not.
A reading nook under a single window
We build the smaller version under a standard window for $500 to $4,000. The price follows the width and whether the seat lifts. It is the cheapest built-in in the house per foot and the one that changes a room most, because it turns dead wall under a window into somewhere to sit.
A daybed at full mattress depth
We build to full depth where somebody is going to sleep on it rather than perch. That runs $1,000 to $8,000 and usually carries drawers underneath and a fitted surround. Depth is what drives your number. Past a point the seat needs its own front rail and legs instead of hanging off the wall behind it.
How we fit it to your room
-
We pattern your opening rather than measure it
We make a full-size pattern of the bay and take it back to the shop. The two side walls are almost never the same angle, and a pattern records that where three numbers on a pad do not.
-
We find out what your radiator needs
We check the radiator under the window and keep air moving through the seat. One boxed in behind a solid front takes the heat out of your room and warms the seat enough to move the wood.
-
We build your seat as a frame
We put a front rail and cross rails under the top and treat the lid as nothing but a lid. This is furniture that carries an adult, and a top on its own will not do that for long.
-
We set the height off your sill and your cushion
We take the finished height from both together. A seat built too high leaves your knees up around your chest, and one built too low reads as a step rather than somewhere to sit.
-
We finish the faces you will never look at
We coat the underside and the back. An original window sheds condensation onto the sill all winter, and that water finds the bare side of a panel before it finds anything else.
What a window does to a seat
A seat is furniture, and no permit attaches to it
Building a seat into a bay that already exists counts as an ordinary repair, so you need no building permit. Cutting the sill down, removing framing or changing the window opening is a different job. That is the point where a seat stops being cabinetry, and we tell you before you sign which side of it your plan sits on.
The lid gets tested, the frame gets loaded
A seat lid opens far less often than a drawer and carries far more when it is shut. So the hinge and the frame under the top decide whether your seat still lines up in ten years, not how many times the lid can open. We fit a Blum lift-up hinge rated for the weight of the lid and build the frame to carry a grown adult.
Condensation is a winter problem in this housing stock
An original window gets cold enough in February to condense the room's own air onto the glass. That water runs down to the sill and into whatever sits under it. Humidity here runs from below 20% in winter to the sixties in summer, so the wood is moving while it is getting wet. We build your box from plywood, which handles that where particleboard swells at the edge and stays swollen.
This finish takes shoes rather than fingers
We use Sherwin-Williams Emerald Urethane Trim Enamel on a seat. It recoats in 4 hours against the 16 that Benjamin Moore ADVANCE wants, and both need 30 days to reach full hardness. That matters more on a seat than on a door, because the first thing to land on it is usually a heel, and a finish that is only touch-dry takes a mark that stays.

Built-in cabinetry in Lynn runs $500 to $1,200 per linear foot with doors and drawers, $200 to $550 semi-custom, and $300 to $850 for open shelving. A full wall of built-in bookcases prices as one job rather than by the foot, at $2,000 to $7,500. What moves your number is the height and how far off straight your wall runs.
| What the job is | Typical range | Unit |
|---|---|---|
| Built-in bookcases and shelving, priced by the footFloor to ceiling against a finished wall. The spread is mostly about height and whether the shelves are fixed or adjustable, because adjustable means boring every shelf position twice. | $300 – $850 | per linear foot, installed |
| Built-in bookcases, a full wallThe same job counted across a room rather than per foot. Includes scribing to the wall and the ceiling, which on an older house is most of the fitting time. | $2,000 – $7,500 | installed |
| Custom built-in cabinetry, priced by the footDoors, drawers and a finished face rather than open shelving. Same per-foot economics as a custom kitchen because it is the same construction. | $500 – $1,200 | per linear foot, installed |
| Semi-custom built-in cabinetry, priced by the footCatalog boxes fitted and trimmed to look built in. Cheaper, and the giveaway is always the filler strip at the wall. | $200 – $550 | per linear foot, installed |
| Home office desk and surround, built inA worktop, drawers, a file bank and the shelving over it, fitted to the room. The top of the range is a full wall in a large room with a hardwood face. | $3,500 – $20,000 | installed |
| Window seat, standard installationA fitted seat under an existing window with storage under the lid. On a Lynn bay window the fitting is the job, because the two side walls almost never return at the same angle. | $2,500 – $3,500 | installed |
| Reading nook seat, smaller openingThe cheaper version under a standard window rather than a bay. Priced on the width and whether the seat lifts. | $500 – $4,000 | installed |
| Built-in daybed under a windowFull mattress depth rather than a seat, usually with drawers underneath. The top of the range carries panelling and a fitted surround. | $1,000 – $8,000 | installed |
| Mudroom lockers and bench, cabinetry onlyAn open locker bay per person with a bench, hooks, a drawer under and a shelf over. Cabinetry only, in an existing room. No framing, no roof, no floor. | $2,400 – $9,600 | installed |
| Butler's pantry or wet bar cabinetryA short run with uppers, a counter and usually glass fronts. Common in the older houses on this side of the North Shore, and often still there behind a later partition. | $3,000 – $12,000 | installed |
Want yours measured properly?
We come out, measure the opening at three heights and check how far off square your walls sit, then put a written number on it before anything is ordered.
Questions we get asked
How much does a window seat cost in Lynn?
$2,500 to $3,500 for a fitted seat with storage under the lid in a bay. We build a smaller nook under a standard window for $500 to $4,000, and a full-depth daybed with drawers beneath it for $1,000 to $8,000.
Why does a bay seat cost more than a straight one?
The angles, and nothing else. A bay's two side walls rarely come back the same. So your seat is patterned and cut to four angles rather than built to three measurements, and that fitting is most of the labor on the job.
Can you build a seat over a radiator?
Yes, with a grille in the front and the back left open. A radiator sealed inside a solid box stops warming your room and starts warming the seat. That moves the wood and cracks the finish along the front edge.
Lift lid or drawers under the seat?
Drawers, whenever the depth allows them. A lid means clearing your cushions off every time, so it gets opened twice a year. A drawer under the front gets used weekly and earns the extra money.
Will the seat sit level if my floor is not?
It will read level to you, which is the part that matters. A bay sticks out past the foundation and the floor inside it has usually dropped. So we build to a level line and trim the base down to what your floor is doing.
Who builds window seats near me in Lynn?
Custom Cabinets Lynn builds bay seats, nooks and daybeds across Lynn and the North Shore. We pattern your bay before cutting anything, because the angle at one end is never the angle at the other.
Nobody wants a window seat with a gap at one end and a lid that slams on small fingers. We pattern your bay in one piece, build the seat as a frame that holds an adult, and hang the lid on a hinge that lowers it slowly. We would rather spend a morning making a pattern than a week explaining a gap.
If a bench with hooks over it is nearer what you want, mudroom lockers and benches covers that version. Built-in bookcases and shelving is what usually goes on the walls either side of a bay, and everything we handle lists the rest.
