407 2nd St is a masterfully renovated, light-filled townhouse in the heart of Park Slope, where timeless charm meets modern elegance. This 20 ft wide home is one of few on its block and has approximately 1000 sq ft of unused FAR. The striking owner's duplex seamlessly fuses 19th-century craftsmanship with high-end contemporary updates to create a warm, sophisticated home in one of Brooklyn's most sought-after neighborhoods. The parlor floor showcases beautifully preserved period details, including exposed brick walls, original wood and stained-glass entry doors with decorative wrought iron, rich wood trim, a fully restored staircase with an ornate newel post and handrail, and a functioning fireplace. These historic elements are paired with a spacious and modern open-concept layout featuring custom built-ins that flow from the living area through the dining space and into the sleek, modern kitchen. The kitchen is both stylish and functional, highlighted by white cabinetry, a Serge Mouille ceiling fixture, and a waterfall-edge island that offers even more storage. Central heating and cooling as well as a humidifier system connected to the water system are discreetly integrated via custom vents for year-round comfort. A tucked-away powder room with marble tile and clever under-stair storage add convenience and sophistication. Sliding glass doors lead to a spectacular two-tiered Ipe wood deck-perfect for entertaining-with a designated dining area and a walkable skylight that filters light down to the garden level. The front and rear yards are professionally landscaped and include bluestone pavers, lush plantings, lighting, and irrigation. Upstairs, natural light pours in through three skylights, illuminating three bedrooms, including a serene, rear-facing primary suite. This tranquil retreat features custom built-ins, a generous walk-in closet, and a luxurious bathroom with marble tile, a jacuzzi tub, double vanity, and heated towel rack. Two additional bedrooms-each with custom millwork and ample closet space-share a second full bath. A full-size washer and vented dryer add to the home's thoughtful layout and convenience. The garden level apartment offers a bright, open feel that's rare for garden-level homes. Enter into an open concept south facing living area that seamlessly flows into an updated kitchen with stainless steel appliances and renovated full bathroom. The rear of the home offers two spacious bedrooms, each with direct access to the yard. This unit is ideal as a turnkey high-income rental or comfortable guest suite. The finished cellar has been cleverly divided into two distinct areas. The rear section can function as an extension of the owner's unit or as bonus space for the garden apartment, complete with a kitchenette, additional living area, full bath, and direct yard access. This section has access to a second washer/dryer, ideal for your tenants or guests. The front section of the cellar is home to the building's mechanicals and also provides ample storage, a home workshop, and bike storage.
