Description

A full-floor residence directly on Park Avenue, offering approximately 4,400 square feet of gracious living across five bedrooms, four full en-suite baths, and a powder room off the main gallery. A private elevator opens to a welcoming gallery that leads into a bright, dual-exposure living room overlooking Park Avenue and complete with a wood-burning fireplace. Also off the gallery, a cozy library with a second wood-burning fireplace offers a quiet retreat within the home. A sizable formal dining room sits nearby, well suited for refined entertaining. The layout achieves a masterful separation between entertaining and private spaces. A wide hallway off the main gallery leads to four large bedrooms, each a sanctuary with its own en-suite bath. The chef's kitchen is designed for both culinary exploration and social interaction, flowing into the formal dining room adjacent to the living room, a sequence that marries functionality with comfort. Additional features include a laundry room, high ceilings, central air conditioning, and extensive closet space. Situated at Park Avenue and 77th Street, 860 Park Avenue is a 1925 architectural landmark by York & Sawyer, distinguished by its gracious proportions and exclusive full-floor residences. The building sits within one of Manhattan's most coveted neighborhoods, moments from top-tier restaurants, art galleries, museums, and shopping. Some photos are virtually staged.

The 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. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
