These custom fireplace built-ins were designed for a home in Narragansett, Rhode Island. The goal was to add useful storage and display space on both sides of the existing fireplace while making the new cabinetry look like it had always been part of the room.

Rather than replacing or altering the original mantle, the new cabinets were designed around it and finished to complement the existing oak.

Drag to compare. The original mantle and surround were left untouched — everything to either side of it is new.

The Challenge

The existing fireplace and mantle already had a distinct wood tone and trim profile, so the new cabinetry needed to fit the available space while visually tying into the original construction.

The project required:

  • —Cabinetry sized specifically for the existing openings
  • —A wood and finish combination that complemented the existing mantle
  • —Trim details that visually connected the new cabinets to the fireplace surround
  • —A design that added storage without making the fireplace wall feel overly heavy

The Design

Before construction began, the built-ins were modeled in 3D so the homeowner could see the proportions and layout in the room.

The final design used cabinets on both sides of the fireplace with glass-front upper sections for display and enclosed lower storage.

The surrounding trim was designed to wrap into the existing mantle area so the finished installation would read as one unified piece rather than separate freestanding cabinets.

Matching the Existing Woodwork

The hardest part of this project had nothing to do with joinery. It was color.

The mantle had not been stained and top-coated the way most modern trim is. Testing showed the original finish was shellac, which changed the entire approach — shellac ambers as it ages, and decades of daylight in a south-facing room had pushed the mantle far warmer than any new board comes out of the stack.

Standard amber shellac straight from the can did not land on the right color. Held up against the mantle, new oak still read noticeably lighter and cooler than the original woodwork.

So the finish had to be mixed rather than bought. Several sample boards were coated with shellac cut with different dye combinations, then carried back to the fireplace and compared in the room's own light. That cycle repeated until one of them disappeared against the mantle.

The result was a warm amber-red tone that sits comfortably beside the original woodwork — without pretending that new oak is the same thing as decades-old oak. Getting a perfect match is usually the wrong goal. Getting a match that reads as intentional is the right one.

Built in the Shop, Fitted to the Home

The cabinetry was fabricated in the Corner Woodshop and then installed and trimmed on site.

Because the cabinets were designed specifically for the room, the final installation could account for the actual walls, fireplace dimensions, trim and surrounding architecture rather than relying on standard cabinet sizes.

That matters more than it sounds. Walls in an older home are rarely plumb and almost never square to each other. Scribing trim to the wall on site is what keeps a built-in from looking like a bookcase pushed against the plaster.

The Finished Result

The completed built-ins provide additional storage and display space while keeping the fireplace as the focal point of the room.

The goal wasn't simply to put cabinets next to a fireplace. It was to make the entire wall feel intentional.

Details

Glass-front doors keep the upper sections light rather than adding two solid blocks to the room, and the cap and base mouldings were profiled to carry the same lines as the existing fireplace surround.

FAQ

Narragansett Built-In Questions

Can you build fireplace built-ins around an existing mantle?+

Yes. On this Narragansett project the original mantle and surround were left completely untouched, and the new cabinetry was designed around them. Building around what is already there is often better than replacing it — it preserves the character of the room and keeps the fireplace as the focal point.

How do you match new wood to existing woodwork?+

It starts with identifying the original finish, because the approach for shellac, lacquer, oil and modern polyurethane are all different. From there we make sample boards, test them against the actual woodwork in the room's own light, and adjust until the color reads right. On this project that meant mixing dyes into shellac across several rounds of samples.

Do you design built-ins in 3D before building them?+

Yes. Every built-in is modeled in 3D first so you can see the proportions and layout in your room before anything is cut. It is far easier to move a shelf or change a door style in a model than after the cabinet is built.

Are built-ins made in the shop or on site?+

Both. The cabinetry is fabricated in the shop where the tools and dust collection are, then installed and trimmed on site so the final fit accounts for the real walls, floors and existing trim. Scribing on site is what makes a built-in look built-in rather than placed.

What parts of Rhode Island do you build fireplace built-ins in?+
