This solid brick single-family home sits proudly on an enormous 40x100 lot-an offering so rare that it truly stands out from anything else in the neighborhood. With a traditional three-bedroom duplex layout, this residence blends classic Brooklyn charm with endless potential. The first floor welcomes you with a formal living and dining room, along with a galley kitchen. Throughout the home you'll find beautiful parquet floors and well-preserved architectural details that add warmth and character. Upstairs are three spacious bedrooms and a full bath, while the basement-featuring a separate front entrance-offers additional living space, a second bath, and flexibility for recreation, storage, or guest use. Practical features include a large garage and community driveway access. But the crown jewel of this property is the land itself: a park-sized backyard and side yard that sets this home apart. Most brick homes with community driveways have little to no backyard-here, you get the opposite: an expansive outdoor space perfect for entertaining, gardening, play, or even considering future development. With R4 zoning, the property offers the rare chance to expand or build-buyers are encouraged to consult with an architect to explore the possibilities. The home may benefit from cosmetic updates, but its solid structure and bones provide an excellent foundation for a dream renovation. The location is equally appealing: nestled on the border of Gerritsen Beach and Marine Park, just a few blocks from Marine Park and the Salt Marsh Nature Center. Nearby transit includes the B3 on Avenue U and the B31, connecting you easily to the rest of Brooklyn. This is more than just a house-it's a once-in-a-lifetime chance to own a double lot property with unmatched space, flexibility, and future potential in one of Brooklyn's most desirable residential enclaves.
