Description

An exceptional and exceedingly rare opportunity to acquire a full-floor condominium residence in the heart of Carnegie Hill, one of Manhattan's most established and architecturally distinguished neighborhoods. Nestled just off Madison Avenue on a picturesque tree-lined block moments from Central Park, this 4,066-square-foot home offers an extraordinary combination of privacy, scale, light, and flexibility rarely available within boutique condominium living. Serviced by a private elevator landing, the residence opens into a dramatic gallery entrance that unfolds into a series of grand yet inviting entertaining spaces. Oversized southern and western exposures bathe the home in beautiful natural light throughout the day, while tranquil treetop views create a sense of serenity and separation from the city below. The expansive living room, centered around a wood-burning fireplace, offers remarkable scale for entertaining while maintaining an intimate residential feel. Designed for both formal entertaining and everyday living, the oversized eat-in kitchen is exceptionally appointed with dual Sub-Zero refrigerators, a full-size wine refrigerator, fully vented Miele six-burner cooktop, dual wall ovens, two sinks, and two dishwashers. A separate dining room located just off the kitchen offers additional flexibility and can function beautifully as either a formal dining room for large gatherings or a comfortable den for more casual everyday living. The bedroom wing is thoughtfully separated to provide maximum privacy. A gallery-style hallway leads to the primary bedroom wing, creating a natural transition from the home's entertaining spaces. The primary suite is quietly positioned and features a custom wood-paneled dressing room and an elegant five-fixture bath, creating a true retreat within the home. Three additional bedrooms are accompanied by a substantial bonus room offering extraordinary flexibility, ideal as a library, media room, home office, fitness room, playroom, or guest suite depending on one's needs and lifestyle. Throughout the residence, timeless architectural details, impressive proportions, abundant storage, and oversized closets reinforce the feeling of a sophisticated private home rather than a traditional apartment. The property also includes a full laundry room. With only eight residences and full-time doorman service, this boutique condominium offers a uniquely discreet and intimate living experience in one of the most coveted pockets of the Upper East Side, surrounded by celebrated restaurants, museums, Madison Avenue boutiques, and the timeless charm that defines Carnegie Hill. Please note: Listing photos have been virtually staged. Please reach out to exclusive agents Luca Signorini & Janet Wang to make an appointment.
