520 Park Avenue

520 Park Avenue is a limestone-clad, full-service condominium completed in 2018 and rising 54 stories with just 35 private residences, mostly full-floor simplex and select duplex layouts. Designed by Robert A.M. Stern and developed by Zeckendorf, the tower reinterprets classic Upper East Side architecture with modern proportions and finely detailed stonework. Interiors typically feature 11-foot ceilings, floor-to-ceiling and bay windows, French-herringbone white oak floors, private key‑locked elevator landings, formal entrance galleries, generous entertaining rooms, and bespoke Christopher Peacock kitchens equipped with Sub‑Zero, Wolf and Miele appliances. Primary suites occupy dedicated wings with large walk-in closets, dual marble-clad baths and radiant-heated floors; secondary bedrooms have en‑suite baths and abundant storage. Building amenities deliver a resort-style resident experience: a double-height 25-meter indoor pool beneath a landscaped skylit garden, a bi-level fitness center with private training and Pilates rooms, spa facilities with sauna and steam rooms, treatment suites, a salon and screening room, a residents’ lounge/club, wine cellar, children’s playroom, private and cold storage, bike room, and 24/7 doorman and concierge. The property sits at 60th Street between Park and Madison Avenues, steps from Central Park, Fifth Avenue retail and major cultural institutions, offering an Upper East Side lifestyle defined by quiet refinement, full-service convenience, and dramatic park and skyline views. Pets are permitted and select units include private storage.
