520 Park Avenue

520 Park Avenue is a 54‑story, limestone‑clad condominium tower completed in 2018 and designed by Robert A.M. Stern. The building contains an ultra-low-density collection of primarily full‑floor and multi‑floor residences—three‑ and four‑bedroom simplex and duplex layouts—totaling roughly 35 units and emphasizing expansive volume and classical proportions. Typical homes feature 11‑foot ceilings, select‑cut white oak herringbone floors, oversized bay and corner windows, private key‑locked elevator landings, formal entrance galleries, generous walk‑in closets, and high‑end kitchens by Christopher Peacock equipped with Sub‑Zero, Wolf and Miele appliances. Bathrooms are finished in marble with radiant floors, steam showers and soaking tubs; many units also include libraries, dens, separate service corridors, and in‑unit laundry. Common areas and services reflect a white‑glove program: a double‑height marble lobby with full‑time doorman and concierge, a two‑story fitness center with Pilates and private training rooms, treatment suites with sauna and steam rooms, a vaulted 25‑meter indoor swimming pool beneath a landscaped garden salon, screening room, wine cellar, children’s playroom, bike room and private storage. The building offers on‑site staff, private storage transfers with sales, and pet‑friendly policies in line with high‑end condominium standards. Sited on Park Avenue at the Plaza/Upper East Side edge, the tower presents framed views of Central Park, the Manhattan skyline and river vistas from many residences. Its classical materials, meticulous millwork and restrained exterior presence aim to evoke the neighborhood’s prewar elegance while providing contemporary systems and amenity scale suited to residents seeking privacy, formal entertaining spaces and proximity to museums, luxury retail and Central Park.
