1040 Fifth Avenue (informally known as the 10 40) is a luxury residential housing cooperative in the Upper East Side of Manhattan, New York City.
Architecture critic Paul Goldberger describes 1040 Fifth Avenue as being one of "the great apartment houses of the 1920s."
10 40 is one of the tallest of the limestone-clad apartment houses on Fifth Avenue, this prominent 17-story structure has one of the most distinctive rooflines along the avenue.The canopied entrance has very attractive cast-iron doors and extensive sidewalk landscaping.
The facade, which has had many repairs, is relatively plain except for several sculpted faces at the fifth story. The large building has only 27 apartments and has had many prominent residents including the late Jacqueline Kennedy Onassis who purchased a penthouse apartment on the 15th floor in 1964 and lived there for thirty years until her death in 1994.
The building was erected in 1930 and was designed by Rosario Candela, one of the city's most prominent designers of luxury apartment buildings in the late 1920s and early 1930s.
The asymmetrical roof, which is setback and clad in a pale yellow brick, has several tall arches whose openings were filled nicely with huge windows in the late 1990s in a remodeling of the spectacular penthouse. The handsome rooftop design is somewhat similar to the roof at Ten Gracie Square, which was erected in the same year and designed by Van Wart & Wein with Pennington & Lewis.
In addition to Jackie Kennedy, Generoso Pope was the second notable resident who lived in the apartment building.
