    323 Prospect Avenue Built in 1901 Two-Family Row House Lot: 18.42ft x 80ft Building: 18.42 x 30ft (plus an extension on the garden level) Delivered Vacant Set among South Slope’s characteristic rowhouses, 323 Prospect Avenue is a lovely two-family house that allows incredible flexibility of use. Currently configured as a lower 2-bedroom, 2-bathroom duplex with basement and a private backyard, and an upper 2-bedroom, 1-bathroom duplex, this charming home could easily be converted into a spacious single-family residence. The lower duplex was extensively renovated by the current owners, creating a warm and inviting home that blends thoughtful updates with original character. The kitchen features custom cabinetry and beautiful Italian Pietra Cardoso stone island and countertops. A custom-built bookshelf in the living room cleverly converts into a functional workspace. Original brick walls and fireplaces, together with beautiful cherry floors, add warmth and texture throughout. The rear of the property houses the sun-filled primary bedroom with en-suite bath, overlooking the peaceful backyard which has been lovingly cultivated as an organic garden for many years. Filled with mature plantings and flowers such as a native serviceberry, lilacs, roses and daffodils, and blessed with abundant sunlight and privacy, the garden is a true sanctuary in the city. The upper duplex retains the charm and character of the original house, with exposed brick walls and original tin ceilings. With two bedrooms, a full bathroom, and flexible layout spread across two floors, the apartment offers a wonderful sense of separation and privacy. Together, the two apartments create a flexible home that can accommodate a variety of living arrangements and evolve over time. Ideally located close to Prospect Park, the R train at Prospect Ave and the F/G trains at 7th Ave station, 323 Prospect Ave offers the best of Brooklyn living within the vibrant neighborhoods of South Slope and Greenwood Heights. This special home is surrounded by the restaurants, cafés, shops, and everyday conveniences that make Park Slope so desirable, such as Giuseppina’s, Folk, Buttermilk Bar and many others.
