Bernard Madoff Luxury Penthouse

Publisher Conde Nast’s duplex penthouse at 1040 Park Avenue was one of the earliest penthouse apartments in New York City. The idea of this penthouse was created according to changes in building’s construction plan. In 1923, the original plan for the building was to have three units on each floor with additional maids’ rooms on the roof. However, in 1924 the building’s upper spaces were constructed to provide a grand duplex for Nast. Connected by a stair case to the rooftop entertaining salons, the corner unit at the top floor was redesigned to be private family quarters. The whole unit was decorated in the French manner by Elsie de Wolfe. Completed in 1925, Conde Nast’s duplex penthouse was used for many lavish parties which were made famous as much by guest lists as by the entertainment.
Architectural definition

High-rise buildings will often have penthouse structures enclosing mechanics such as those in an elevator machine room.
