One Madison Avenue will soon be redeveloped to become one of the most important adaptive reuse projects of recent New York history.

Shiny Jewel Box

Kohn Pedersen Fox with Hines and Gensler, are building on this history of the building and adding 26 floors to the additional structure.  A new shiny tower will be a magnificent jewel box of that will elegantly compliment the original structure.

Many of the floors will provide spectaculary Madison Square Park views.



The original building was built in 1893 and designed by the esteemed Napoleon Le Brun & Sons. When it was completed, One Madison Avenue was one of the city’s largest office buildings, spanning the full block between Park and Madison Avenues and East 23rd and East 24th Streets.  In 1909 the building gained its famed clock tower (now a separate building) which was for a time the tallest building in the world.  When completed, the campus was an international sensation in the architectural community, for its rapid construction as well as its soaring design.

The building was built before Midtown Manhattan was even considered a desitination for office buildings.

In the 1950's, the building was completely rebuilt by D. Everett Waid and 11 Madison was added directly north.

With a projected completion date of 2024, the finished structure will join the MetLife clock tower, 11 Madison and the Flatiron Building as one of the many distinguished buildings that make the Flat Iron neighborhood.
