Description
One block from Central Park, Residence 2A at 51 East 90th Street embodies the gracious proportions and enduring character of classic Carnegie Hill. Set along one of the neighborhood’s most desirable tree-lined blocks, this south-facing two-bedroom, two-bathroom residence offers three exposures, beautiful parquet floors, and the rare distinction of a separate formal dining room. The living and dining rooms create an elegant setting for both everyday living and entertaining, with generous proportions and a natural sense of flow. A classic butler’s door connects the formal dining room to the windowed kitchen, preserving the apartment’s traditional separation of spaces while adding to its functionality. The kitchen features a built-in wine rack and a private service door opening directly to the building’s service entrance. Double-pane windows throughout provide a quieter, more comfortable interior. The oversized primary bedroom enjoys corner exposures and an en-suite bath, while the second bedroom—currently configured as a private home office—offers flexibility as a bedroom, guest suite, or study. Both bathrooms are finished in floor-to-ceiling Italian marble and present an opportunity for a refined contemporary update. The well-proportioned layout offers additional possibilities for customization, subject to architectural review and required approvals, including the potential to reimagine the formal dining room as a third bedroom, generous den, or additional living space. Designed by architect George Pelham and completed in 1928, 51 East 90th Street is an intimate, full-service cooperative comprising just 38 residences. Building amenities include a full-time doorman, attended service elevator, live-in superintendent, bicycle storage, laundry room, and private storage, subject to availability. In-unit washer/dryers and through-wall air conditioning are permitted. The pet-friendly cooperative also permits pied-à-terre ownership and up to 60% financing. A monthly capital assessment of $1,286.25 remains in effect through June 2027. Ideally situated in Carnegie Hill, the residence is moments from Central Park’s Engineers’ Gate and the Jacqueline Kennedy Onassis Reservoir, and Museum Mile. Nearby schools include The Dalton School, Saint David’s School, The Spence School, The Nightingale-Bamford School, and Convent of the Sacred Heart. With its exceptional location, prewar character, gracious proportions, and potential for thoughtful modernization, Residence 2A presents a rare opportunity to create a distinctly personal home in one of Manhattan’s most coveted neighborhoods.

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
