Description
Park Ave. & 82 nd St - Prewar Classic 8 Ideally positioned on the ninth floor of one of Park Avenue's most distinguished prewar cooperatives, this exceptional Classic 8 occupies the entire west wing of the building, offering extraordinary natural light, open city views and a wonderful sense of space and privacy. Designed by renowned architect J.E.R. Carpenter, the residence is distinguished by oversized picture windows spanning all four exposures, allowing sunlight to pour into virtually every room throughout the day. A private elevator vestibule opens onto an expansive gallery, leading to an impressive 41-foot succession of elegant entertaining rooms. Rich in authentic prewar character, the apartment features soaring 10-foot ceilings, handsome herringbone floors and beautiful original moldings. The gracious living room, anchored by a wood-burning fireplace, enjoys magnificent western exposures, with views extending to the Metropolitan Museum of Art just two blocks away. The well-appointed eat-in kitchen has a southern exposure and offers a comfortable banquette breakfast area. An exceptionally large adjoining pantry provides abundant storage and incorporates a conveniently located washer and dryer. The private and pin-drop quiet south wing of the residence comprises four bedrooms and three bathrooms. Three of the four bedrooms are generously proportioned and enjoy exceptional natural light and open city views through oversized picture windows-a particularly desirable feature rarely found in Park Avenue's classic prewar cooperatives. Completed in 1921, 950 Park Avenue is a magnificent Palazzo-inspired building designed by J.E.R. Carpenter. Residents enjoy an outstanding level of white-glove service, privacy and security. Amenities include a rooftop fitness center, a beautifully landscaped roof garden terrace with sweeping views toward Central Park, and private basement storage.

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.

Broker Commission Disclosure: Broker commissions are not set by law and are fully negotiable.
How working with a buyer's agent works: I work for you, not the seller. Before I show you anything, New York brokerage rules ask us to put that in writing: an agreement and a disclosure that say I work for you and negotiate on your behalf. The agreement is non-exclusive: you can work with other agents, it runs for a short fixed term we agree on, and you can end it with a note. You may attend open houses independently without an agreement. Read how it works
