Description
Occupying the entire sixth floor of one of Park Avenue's most distinguished prewar cooperatives, Residence 6 at 860 Park Avenue is a remarkable approximately 4,400-square-foot home that masterfully balances grand-scale entertaining with the comfort and intimacy of everyday living. Designed by the celebrated architectural firm York & Sawyer and completed in 1925, the building remains one of the avenue's most coveted addresses, embodying the elegance, craftsmanship, and enduring quality of New York's golden age. A private elevator landing opens directly into an impressive marble gallery, creating a dramatic sense of arrival and an ideal backdrop for a significant art collection. From there, the residence unfolds with exceptional scale and proportion. The gracious 28-foot living room is bathed in natural light and anchored by one of two stately wood-burning fireplaces, while nearly ten-foot ceilings, recessed cove lighting, and oversized sash windows lend warmth, volume, and architectural distinction. The formal dining room is equally impressive, offering an elegant setting for both intimate dinners and large-scale entertaining. It flows seamlessly into a beautifully appointed chef's kitchen, where timeless yet contemporary custom cabinetry is paired with premium appliances by Miele, Viking, Bosch, and Sub-Zero. Designed with both functionality and entertaining in mind, the kitchen also features a full-size indoor barbecue with commercial-grade exterior venting, a discreet service entrance, and an adjoining breakfast room flooded with natural light. A private five-foot-wide corridor leads to the exceptional primary suite, one of only two residences in the building to enjoy the most expansive bedroom configuration. This serene retreat features a custom walnut dressing room and a luxurious spa-inspired bath clad in travertine marble, complete with dual vanities, a glass-enclosed shower, and a deep soaking tub. Three additional generously proportioned bedrooms, each with substantial closet space and en-suite baths, provide exceptional flexibility for family and guests. A richly paneled cherry wood library, centered around its own marble fireplace, offers a sophisticated and inviting setting for work, reading, or quiet reflection. A staff room with full bath further enhances the home's versatility. Throughout the residence, original prewar details have been meticulously preserved and thoughtfully integrated with modern conveniences, including oak floors with decorative border inlays, tray ceilings, four-zone central air conditioning, integrated surround sound, and abundant custom storage. The apartment has been impeccably maintained and conveys with two private storage units. Perhaps most compelling is the extraordinary level of privacy. With just fifteen residences—one per floor—860 Park Avenue offers a discreet and intimate living experience that is increasingly rare in Manhattan. Ideally situated at the corner of East 77th Street, moments from Central Park, Museum Mile, and the finest shopping and dining of the Upper East Side, the building provides white-glove service, exceptional stewardship, and the timeless appeal of one of Park Avenue's most exclusive addresses. Pets are welcome.

About Upper East Side
View All Upper East Side ListingsThe Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle.
