This Brooklyn brownstone renovation was a full gut project in every sense of the word. On top of installing new floors, a kitchen and bath renovation, and all the typical restoration and refinishing involved in a brownstone built in 1899, we also completely updated the exterior, constructed a balcony that was not originally there, and converted the space from a single-family home into an an owner’s triplex. A newly separated studio rental on the garden level offers the opportunity for supplemental income, an uncommon and welcome addition to a New York brownstone.
The result is a two-family brownstone that perfectly combines classic townhouse living with today’s modern needs, including SmartHome technology that we installed to control Bluetooth speakers, Nest thermostats, and the security system.
The overall aesthetic goal of this brownstone renovation was to pay homage to the historical periods the building has lived through in a cohesive way that is the hallmark of modern transitional style in New York City brownstone interiors.
In the kitchen, white Shaker-style cabinetry, a subway tile backsplash, and marble rather than quartz countertops bring a classically upscale sensibility. To modernize the space further, we opened up the back wall to create floor-to-ceiling windows that are also doors, opening up into the newly built balcony.


This brownstone renovation included many quintessential elements, such as millwork like the ceiling medallions. We restored some and custom built others, perfectly recreating their original appearance.
The heated master bathroom is now serene, with a walk-in shower featuring a subtly modern linear drain. A herringbone Carrera marble tiled floor and marble slab sink complete the scene. In the powder room, we embraced a contemporary look by pairing dark hexagonal floors with light chevron tiles, accented with dramatic navy blue wallpaper. With its clear-cut 1920s-style, we selected the wall sconce to reference one of the brownstone’s earlier eras.
Natural oak herringbone floors we installed throughout the entire home bring a modern yet warm touch. We restored the wood-burning marble fireplace, which is fully functioning. An elegant staircase with a custom-crafted black wooden banister and white balusters winds up and down alongside a real brick interior wall that we restored and refinished.
In this brownstone renovation, we were also able to create ceiling height, an unexpected yet aesthetically pleasing side benefit. When working on the joists and beams to level out the floors (a common issue in pre-war renovations) we added ceiling height in the main parlor floor by taking the second floor and raising the ceiling an entire foot. The end result is a main floor with stunning 9-foot ceilings.
Fun Fact: This Bed-Stuy home is a true brownstone, meaning it was constructed from actual brownstone, which we also completely redid for this project.

For a full apartment of about 1,700 square feet, construction typically runs five to six months. Design, board approval, and permitting come first and usually take four to six months, so most full renovations move from first consultation to move-in in 10 to 12 months. Scope, building rules, and how much infrastructure is being replaced set where a project falls in that range.

The construction portion of a full kitchen renovation typically takes 7 to 11 weeks. Door to door, the timeline depends mostly on the building: about 10 to 14 weeks in a private townhouse, 14 to 20 weeks in a condo, 16 to 24 weeks in a post-war co-op, and 20 to 30 weeks in a pre-war co-op, where board and engineering review take longer. Gallery KBNY orders custom cabinetry, stone, and long-lead appliances during design and approvals, so materials arrive ready for the build.

The construction portion of a bathroom renovation typically takes three to four weeks. Gallery KBNY renovates bathrooms as part of larger interior renovations, so bathroom work is sequenced alongside the rest of the apartment within the overall project schedule.

Board review and execution of the alteration agreement typically take 6 to 10 weeks in a post-war co-op and 8 to 14 weeks in a pre-war co-op, where asbestos filings, electrical load letters, and engineering review add steps. DOB permits usually run at the same time. A complete package with full technical drawings and specifications tends to clear the building's reviewing architect in one or two rounds, which keeps the approval phase on schedule.
