The Koerner is a 1913 rental building at 903 Park Avenue in Carnegie Hill, rising 17 stories with 67 apartments. Its most distinctive residential arrangement is a full floor rental on the top floor, spanning more than 6,600 square feet and combining high ceilings with Park Avenue facing rooms and abundant natural light.
The top floor residence occupies an entire level rather than following a typical apartment footprint, with separate living, entertaining, bedroom, office, gym, and service areas organized across the floor. Its scale also allows for staff accommodations and a dedicated service wing, details that set this apartment apart from the building’s more conventional layouts.
The Koerner operates as a full service, white glove building with a 24 hour doorman, and pets are permitted. Lease terms range from three to thirteen years without rent increases, making the building’s rental offering unusual in duration as well as in the size of its top floor residence.
