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.
