This property presents a unique opportunity to either host a physician’s office or be converted to a spacious 2-bedroom 2 bath residence. The building itself is steeped in history and architectural grandeur. Designed in 1928 by Raymond Hood and John M. Howells, the celebrated architects behind Rockefeller Center and the Daily News Building, It remains one of Manhattan’s finest examples of Art Deco architecture.

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.

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
