903 Park Avenue

903 Park Avenue is a 17-story residential building in the Upper East Side featuring limestone and brick facades with classical architectural elements throughout. The structure contains approximately 70 units and provides doorman service along with laundry facilities for its residents.

The building was completed in 1914 by architects Robert T. Lyons and Warren & Wetmore, and initially held the title of tallest residential structure in New York City. This achievement made it a notable landmark during a period of rapid urban expansion.

The building reflects Park Avenue's transformation into a residential corridor for wealthy families, with its classical design serving as a visual marker of social standing in the neighborhood.

The building is located near the 77th Street and 86th Street subway stations, offering convenient public transit access to the area. Access is limited to residents as it is a private residential building, though the exterior facade can be viewed from the street.

Maria DeWitt Jesup, widow of banker Morris Ketchum Jesup, purchased the entire building immediately upon its completion in 1914. This single ownership of the entire building was an uncommon transaction in the New York real estate market of that era.
