Description
Perfectly positioned on Park Avenue in the heart of Carnegie Hill, Apartment 4 NE (5th floor) at 1155 Park Avenue presents a rare opportunity to own a beautifully scaled pre-war residence within one of Manhattan’s most admired white-glove cooperatives. This expansive, classic eight-room home offers the proportions and layout that define classic Upper East Side living: three generously sized Bedrooms, a separate Library (easily a fourth Bedroom), three Bathrooms, a gracious entry Foyer, a grand Living Room, a Formal Dining Room, and a large eat-in Kitchen. Plus soaring a bonus Staff Room or home office, 10 foot ceilings and bright North and East exposures. The apartment enjoys wonderful natural light and open city and tree-lined views. The semi-private elevator landing opens to an elegant Gallery, setting the tone for a home designed for both refined entertaining and comfortable living. The apartment offers flexibility for customization while preserving the integrity of its classic pre-war scale. This is a residence with enduring bones — ready to be tailored to the next owner’s vision. 1155 Park Avenue was designed by architect Robert T. Lyons and built by Bing & Bing in 1915, reflecting the elegance and craftsmanship of early 20th-century Park Avenue architecture. This distinguished cooperative offers full-time doorman and concierge service, exceptional staff, and a live-in resident manager. The building permits 40% financing and has a 2.5% flip tax. Located in Manhattan’s coveted Carnegie Hill, residents enjoy proximity to Central Park’s Reservoir, Museum Mile, Madison Avenue boutiques, and some of the city’s finest schools and restaurants. Tree-lined streets, architectural beauty, and a true neighborhood atmosphere make this one of the most desirable enclaves on the Upper East Side.

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. 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.
