910 Union Street, 4B Residence 4B at 910 Union Street presents a thoughtful balance of prewar character and modern design within Park Union, a boutique condominium in the heart of Park Slope. Entered through a private vestibule, this three bedroom, two and a half bath home opens into a well-proportioned living and dining area designed for both everyday living and entertaining. High ceilings with detailed moldings and wide plank Vermont oak flooring create a sense of quiet sophistication throughout. The open kitchen is carefully composed with custom cabinetry, quartz countertops, and a suite of integrated appliances, complemented by a chef's pantry and additional storage. A discreet laundry closet adds convenience without compromising space or flow. The layout offers excellent separation between the primary suite and secondary bedrooms. The primary bedroom is positioned for privacy and includes generous closet space and a refined en suite bath finished in marble with custom fixtures. Secondary bedrooms are well scaled and supported by equally considered baths. Two private outdoor spaces extend the living experience, offering open views and a natural connection to the surrounding neighborhood. Park Union is a full service, elevator condominium with a limited number of residences, originally a prewar structure and thoughtfully reimagined into a modern boutique building. Amenities include an attended lobby, fitness room, playroom, bike storage, and a landscaped roof terrace with expansive views. Positioned just moments from Grand Army Plaza and Prospect Park, the location offers immediate access to green space, cultural institutions, and multiple transit lines, placing the best of Brooklyn and Manhattan within easy reach.
