Description

Now offered at its new price, this nearly 1,600 sq ft Prospect Heights duplex delivers the kind of private outdoor space and flexibility that rarely comes to market. This thoughtfully designed garden duplex is officially a two bedroom, two and a half bathroom home, with a substantial lower level featuring a window, two closets, and access to a half bath. The space offers tremendous flexibility for recreation, guests, work from home needs, or even a potential third sleeping area. Upstairs, the living space feels both open and grounded, anchored by rich Brazilian tigerwood floors and a fully refreshed kitchen with new cabinetry and appliances less than two years old. Every update has been done with intention, including new bathroom vanities and medicine cabinets, a new washer and dryer, and a recently installed HVAC system providing central air and heat. The private backyard is a true extension of the home, offering a rare outdoor experience that is increasingly difficult to find in Brooklyn. Whether entertaining, gardening, or simply enjoying a quiet moment outside, the space adds a level of livability that sets this home apart. Set within an intimate five unit condominium, the building offers a sense of community along with low common charges. Originally built in 1931 and thoughtfully expanded and renovated in 2008, it blends pre war character with modern comfort. Positioned just off Vanderbilt Avenue, you are moments from some of Brooklyn’s most beloved restaurants, cafes, and boutiques, as well as Prospect Park, the Brooklyn Museum, and the Botanical Garden. Chelsea Piers Fitness sits directly across the street, and multiple subway lines nearby provide easy access to Manhattan in approximately 20 minutes. A rare combination of space, flexibility, outdoor living, and location in one of Brooklyn’s most sought after neighborhoods. Come experience it for yourself. Please email or text to schedule an appointment.
