The CitiCorp Building or One Court Square

 

The Citicorp Building stands as one of the Manhattan’s tallest skyscrapers at 153 East 53rd Street. The Citicorp Building stands as one of the Manhattan’s tallest skyscrapers, which was designed by Architect Stubbins Associates, Emery Roth & Sons, is over nine hundred feet tall, and has 59 floors. With a 45 degree angled top and a stilt-style base, It is one of the most imposing structures in the New York skyline. It is the tallest among the Citigroup buildings.


Inside the giant is 1.3 million square feet of leasable space. The building was completed in 1977,

and is now owned by Boston Properties. There were a lot of changes made during its construction.

 

These shifts from the original plans led to a structurally unsound product. Structural engineer William LeMessurier came upon a fatal flaw in the building’s design in 1978. In the original plans, the structure was to have welded joints, but during construction, these were changed to the less expensive bolted variety, which were not strong enough to withstand high speed winds. LeMessurier reported this to Citicorp, and convinced the company to take steps to address the problem without the public finding out about it. Last year, Boston Properties started planning to change the name of the building to 601 Lexington Avenue.
