A five-story red-brick cooperative on the Upper East Side built in 1950, this boutique elevator building contains primarily studio and one-bedroom residences. Units are defined by high ceilings, hardwood floors, oversized windows and practical layouts that often include separate dining areas or pass-through kitchens. Common interiors include a renovated lobby, central laundry room with app-enabled machines, bike storage, and elevator service; a live-in superintendent and an intercom/virtual doorman system handle day-to-day building operations. Outdoors the property sits on a tree-lined block with some apartments offering private outdoor space or small private backyards and immediate access to nearby parks and the East River esplanade. Pet policies are restrictive: cats are generally permitted (typically one per unit) while dogs are not allowed. The co-op’s governance supports flexible buyer scenarios such as co-purchasing, guarantors, pieds-a-terre and limited subletting after an initial ownership period, though investors are generally discouraged. Located steps from Lexington Avenue and the Q and 4/5/6 subway lines, the building is surrounded by grocery options, neighborhood markets, cafés and restaurants, providing a quiet, well-serviced urban residential experience.
