635 Park Avenue offers a rare level of privacy and pedigree in the heart of the Upper East Side. Designed by legendary architect J. E. R. Carpenter, this intimate white-glove cooperative contains just thirteen grand residences and a single maisonette - a uniquely elegant and generously sized 2-bedroom home with 3 large bathrooms, moments from Central Park.

Positioned on the corner of East 66th Street and Park Avenue, this sophisticated maisonette combines classic prewar architecture with thoughtful modern upgrades. High ceilings, original moldings, herringbone floors, and beautifully scaled rooms create a sense of understated grandeur throughout. The expansive living room enjoys natural light from Park Avenue and offers an exceptional setting for entertaining or quiet daily living.

The kitchen has recently been updated with premium appliances, including a Bosch refrigerator, dishwasher, and oven, along with an in-unit Miele washer and dryer - seamlessly integrates contemporary convenience into the home's timeless character.

Privately situated away from the entertaining spaces, the two bedrooms offer exceptional tranquility and generous proportions. A separate space can easily act as a home office or open dining room. Abundant closets and deeded private storage further enhance the home's livability.

Residents of 635 Park Avenue enjoy an exceptionally discreet and attentive level of service, including a full-time doorman, porter, resident superintendent, fitness room, and private storage. Just moments from Madison Avenue boutiques, world-class dining, the museums, the Park Avenue Armory, and Central Park, this is Upper East Side living at its most refined.
