Our clients at 421 13th Street own a three-level, single-family brownstone in Park Slope, just steps from Prospect Park. As a young family with a growing household, they purchased the home after a generic flip left it in builder-grade condition, with standard finishes and no architectural detail worth preserving. For a couple who cook seriously and entertain often, the kitchen fell well short of how they actually live.
Enter Gallery. We scoped the project around a complete kitchen renovation and an expanded, rebuilt primary bathroom, with a refresh extending across all three levels of the home. Hand-selected cabinetry and veined marble surfacing replace the builder-grade finishes throughout, carried through in brass and bronze fixture details. The finished home reflects how the family actually lives and entertains, delivered by our full-service design-build team from initial design through construction.
The centerpiece of the renovation is a complete kitchen transformation on the parlor level, with new flooring installed throughout the space. Built for clients who host often, the kitchen holds a Monogram 36-inch professional rangetop and a Monogram 30-inch built-in wall oven beneath an oversized hood, alongside a matching Monogram 30-inch refrigerator for a coordinated appliance suite. A generous island finished in Benjamin Moore's Hudson Bay 1680 anchors the room against Miralis maple cabinetry: Jacksonville 5051 uppers and Tribeca 5138 lowers, both in a natural finish. A backsplash and integrated shelf in MSI's Calacatta Miraggio Duo marble, polished with eased edges, sits above the range wall. A Poplar 54-inch quad pendant lights the island, with brass-finished sconces along the perimeter.
The layout was planned around how the clients entertain. The island's integrated prep sink, a Blanco Quatrus 22-inch undermount stainless model paired with a Hansgrohe Zesis pull-out faucet, handles daily food prep, while a dedicated bar sink with a brushed-gold Signature Hardware Lexia faucet serves the adjacent coffee station, itself fitted with a Hansgrohe Talis N pull-down faucet. Beside it, a wine bar zone anchored by a 24-inch Zephyr wine cooler supports the homeowners' interest in mixology, and a rear closet was reworked into a walk-through pantry finished in matching Miralis cabinetry and Calacatta Miraggio Duo marble, adding storage while preserving the main kitchen's clean sightlines.

The third floor holds three bedrooms and two bathrooms, and the primary bath had far less room than the suite required. Because the primary bedroom offered a generous footprint, we borrowed space from it to enlarge the bathroom substantially. The rebuilt bath is finished in Corian Quartz's Calacatta Villa, a polished 3cm slab with eased edges, and includes a walk-in shower with a built-in bench and a corner-wrapping niche, set beneath an Ecostat S thermostatic shower system with volume control in a brushed bronze finish. The floor is laid in 24-inch by 24-inch Rushmore Lake Beige tile, with TileBar's Minera Dolomite Warm White 12-inch by 24-inch tile lining the walls.
A fully custom vanity, a single oak veneer piece measuring 5 feet 3 inches wide, with slab-front drawers and doors finished in edge pulls, is topped with a LaCava Aquasei sink in white, with an Aksel floating shelf mounted alongside. A Visual Comfort & Co. Banda 36 sconce in natural brass lights the vanity, and a Robern Craft Series medicine cabinet, framed and soft-close with an electric upgrade, completes the suite.
The renovation touched every floor of the house beyond the kitchen and primary bath. On the ground level, an underused storage room became a pantry and casual lounge area, and the floor was repainted throughout. In the parlor-level living and dining rooms, dated millwork surrounding the fireplace was removed, including a raised platform that crowded the hearth, restoring clean lines to the room. The clients sourced a reclaimed wood beam, which became the new mantel. Existing wood flooring was refinished in a Golden Oak stain to unify the levels. Fresh paint continued throughout the home, including the powder room, alongside closet reconfiguration on the bedroom level.

The design direction is transitional, pairing classic warmth with clean, contemporary detailing. Because the prior flip left no original architectural fabric worth preserving, the project offered room to introduce character deliberately. Natural maple Miralis cabinetry sits against the Hudson Bay blue island, while the same veined Calacatta Miraggio Duo marble appears at the kitchen's backsplash and shelf. In the primary bath, Calacatta Villa quartz and the custom oak vanity continue the material story, with brass and bronze fixture finishes carried from the kitchen sconces through to the bathroom's Banda sconce and Ecostat shower trim. The result reflects the tailored consistency built into Gallery's in-house design-build approach.

Yes. Our project minimum is $400,000.
Renovation costs vary significantly based on apartment size, scope, finish level, existing conditions, and building type. As a general benchmark in Manhattan:
Pre-war buildings typically cost more due to older infrastructure and additional labor requirements.
