Description

Classic Park Slope character meets modern comfort at 430 3rd Street, Residence 3, a spacious three-bedroom plus den, two-bath floor-through condominium on one of the neighborhood's most coveted streets. Beautifully renovated while retaining the details that give a prewar home its personality, the residence features original moldings, working wood shutters, a tin ceiling, high ceilings , and a charming bay window alongside thoughtful contemporary upgrades throughout. The living and entertaining spaces occupy the front of the home, where an open layout brings together the living room, dining area, and recently updated kitchen. Designed around a generous U-shaped configuration, the kitchen features Caesarstone countertops with a waterfall edge, custom Shaker cabinetry extending to the ceiling, and a full Bosch appliance package. A bedroom with custom built-ins sits just off the living room, offering flexibility for guests or additional living space. Engineered hardwood flooring with added soundproofing extends throughout the apartment, while new windows and split-system air conditioning add everyday comfort. A separate den/home office provides another highly functional space and is large enough to accommodate a queen-size bed when needed. Custom built-ins incorporate a cleverly concealed workstation, allowing the room to transition easily between work, guest, and everyday use. Toward the rear of the home are two additional bedrooms and two recently renovated bathrooms. The generously proportioned primary bedroom enjoys two south-facing windows, ample room for a king-size bed and additional furniture, and a wall-to-wall closet. A Bosch washer and dryer are conveniently tucked into one of the bathrooms. Perhaps the home's most exciting feature lies above: deeded rights to approximately half of the building's roof, providing private access and the opportunity to create a rooftop retreat of your own. An intimate, pet-friendly, self-managed four-unit condominium, 430 3rd Street offers exceptionally low common charges and taxes, along with dedicated bike storage and substantial private basement storage for each residence. Currently zoned for P.S. 321, the home delivers an increasingly rare combination of prewar character, flexible space, modern amenities, and private outdoor potential in the heart of Park Slope.
