Description
A grand Park Avenue residence, offered for the first time in generations, with leafy views and a prime location just moments from The Metropolitan Museum of Art and Central Park. Beautifully proportioned and rich in prewar character, this former classic seven is now configured as an expansive six-room home with nearly ten-foot ceilings, elegant crown moldings and beautifully preserved architectural detail. The entertaining rooms are particularly generous: a large living room centered on a fireplace, which can be converted back to wood-burning with board approval, and a formal dining room of substantial proportions, both overlooking the tree-lined avenue. The principal rooms are filled with soft natural light and a changing canopy of greenery. A Sonos sound system extends throughout the home. Three bedrooms and two windowed bathrooms provide excellent separation and privacy. The primary suite includes a windowed en-suite bath with heated floors and extensive closet space. The original maid’s room has been incorporated into the kitchen, creating an exceptionally large windowed eat-in kitchen, approximately 17'10" x 20'. It is equipped with a Wolf range and convection oven, an exterior-vented Wolf hood, Wolf warming drawer, farmhouse sink, Sub-Zero refrigeration with an additional double-drawer freezer, and a Miele dishwasher. A Miele washer and dryer are discreetly integrated into the kitchen. Two unusually large private basement storage rooms, approximately 9' x 13'6" and 11' x 6', are included in the sale. Designed by George and Edward Blum, 840 Park Avenue is a white-glove cooperative offering exceptional service and privacy. Museum Mile is moments away, with the boutiques, cafés and restaurants of Madison Avenue close by.

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
