1107 Fifth Avenue is a grand pre-war apartment building on Fifth Avenue in Carnegie Hill, built in 1925. It was famous for its 54-room triplex penthouse created for Marjorie Merriweather Post Hutton, which was later divided into smaller units. Currently, 1 apartment is for sale.
Located at the southeast corner of Fifth Avenue and 92nd Street in Carnegie Hill, 1107 Fifth Avenue is a distinguished pre-war cooperative built in 1925 by the George Fuller Company and designed by W. K. Rouse & L. A. Goldstone. This 14-story, 26-unit building is celebrated for its prime location on Museum Mile, offering proximity to Central Park, renowned cultural institutions, private schools, and historic mansions.
The building's most famous feature was its original 54-room triplex penthouse, created for cereal heiress Marjorie Merriweather Post Hutton. Considered one of the most luxurious apartments ever built, it included a silver room, wine storage, and dedicated spaces for furs and flowers, along with 18 servants' rooms. The triplex was later divided into smaller apartments. Post also owned the Palm Beach estate Mar-a-Lago, now owned by Donald Trump.
The existing penthouse features grand proportions, multiple fireplaces, and expansive terraces, including a 100-foot-long north terrace and a 75-foot-long west terrace. It boasts a formal gallery, a spacious living room, a library, a dining room, and a well-appointed kitchen with access to a southeast terrace. The unit also includes a smaller one-bedroom apartment, originally part of the Hutton triplex's laundry area, now redesigned with its own terrace.
Architecturally, 1107 Fifth Avenue exhibits classic pre-war details, including a three-story rusticated limestone base, prominent cornices, Palladian windows, and decorative balconies. Though modest in amenities—it offers a doorman, concierge, and private entrances but lacks a garage or sundeck—the building’s exclusivity and Central Park views make it highly desirable.
Notable past residents include Ralph Lauren and Sony executive Howard Stringer. The building has also seen dramatic real estate negotiations, including a contested penthouse sale that involved board-approved roof deck plans. In a unique historical twist, a former resident commissioned an intricate hidden puzzle within their apartment, adding to the lore of this already storied address.

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.
By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
