A low-rise, four-story pre-war co-op built in 1920, this Park Slope townhouse-style building presents classic Brooklyn character with modest scale and a well-maintained brick façade. Units are arranged as traditional walk-ups and feature period details blended with contemporary upgrades: hardwood or original pine floors, exposed brick accents, high ceilings in many apartments, windowed bathrooms, and modernized kitchens and appliances in several residences. The building operates as a cooperative with professional management and stable finances; it is pet-friendly and offers conveniences that include in-unit washer/dryer hookups in multiple units, assigned basement storage (roughly 40–50 sq ft per unit), stroller parking on the first floor, and shared bicycle storage. Landscaped communal outdoor space is a notable asset—a maintained backyard/garden and small courtyard provide private green space for residents. Services are straightforward rather than concierge-driven; maintenance is described as low with cooperative governance. Location is a primary draw: the property sits a block or less from Prospect Park and within easy walking distance of the F/G trains, neighborhood shops, restaurants, a YMCA, cinemas, and a weekly greenmarket. Overall the building blends pre-war architectural warmth, small-building community scale, and practical amenities that support everyday urban living in south Park Slope.
