900 5Th Ave

900 Fifth Avenue is a 20-story, postwar cooperative completed in 1959 and designed in the mid-century tradition by Sylvan Bien. The façade is composed of signature paired bay windows that deliver abundant natural light to oversized rooms and frame long views toward Central Park and the Frick Museum. Units are primarily two- and three-bedroom layouts, often configured around generous entrance galleries, formal dining rooms, eat-in kitchens and staff/den rooms; many residences include terraces, walk-in closets and en-suite bathrooms. Interiors commonly feature restored or high-end finishes, built-ins, and modernized systems such as full-size washers/dryers and through‑the‑wall air conditioning. Common areas are maintained to a white-glove standard: a 24-hour attended lobby with a redesigned, richly paneled entry, a top-floor fitness center, two furnished roof terraces with skyline and park vistas, a bike room (including shareholder bike program), package and storage facilities, and an on-site garage. Building services include concierge, live-in manager, doorman service and full-time staff; monthly maintenance typically covers utilities. The co-op’s policies accommodate pied‑à‑terre and international buyers in many units, permit small pets (weight-limited), and allow limited financing and flip‑tax arrangements depending on the apartment. Located at Fifth Avenue and East 71st/72nd Street, the building sits within the Upper East Side Historic District, directly across from Central Park and the Frick, providing immediate access to museums, galleries, upscale shopping, and subway/commuter connections.
