An amazing oppοrtunitу in а pеrfесt Park Slopе lοсаtiοn! 909 Union Street is a five-story brick-and-limestone townhouse, currently configured as an owner's lower duplex with three simplex apartments above. Spanning approximately 5,300 square feet, it offers true flexibility: hold as a high-performing four-unit rental, convert to condos, or enjoy the mint owner's duplex with substantial rental income upstairs.
The owner's duplex has been thoughtfully renovated for effortless living. The parlor level delivers a nearly 60-foot great-room experience-an oversized living room and generous dining area, all designed to host beautifully. The chef's kitchen is a standout, featuring Bilotta cabinetry, Viking and Bosch appliances, and a River Granite center island with a prep sink, plus dual wall ovens (standard + convection) and a six-burner cooktop-a true cook's dream. The kitchen opens onto a spacious deck, which flows down to the back garden. A renovated powder room is also found on this level.
Downstairs, the garden level features a large bedroom and media room (currently used as the second bedroom). The primary suite opens directly to the garden. The en-suite bath is spa-like, with radiant heated floors, a double vanity, and a jacuzzi tub. A second full bath offers a marble shower and elegant marble-accented flooring. Carrara marble floors throughout the level are among the most recent upgrades, and the large utility/laundry room provides generous storage.
The three upper floors are configured as three charming two-bedroom residences, each with a washer/dryer and dishwasher, plus classic details like decorative moldings and fireplace mantels. The top-floor living room is crowned by a dramatic original stained-glass window-an unforgettable finishing touch.
Situated in the heart of Park Slope, within the original Park Slope Historic District, this home is moments from Grand Army Plaza, Prospect Park, the Brooklyn Museum, the Brooklyn Botanic Garden, Union Market, and access to the B/Q and 2/3 subway lines.
