One Madison Residential Condominium Tower, 23rd Street, Manhattan, Flatiron District, New York City, New York, United States

The building was designed by the architectural firm Cetra/Ruddy.
Nicolai Ouroussoff, the architecture critic for the New York Times, called One Madison Park "a dazzling addition to a street that includes two of the city’s most celebrated skyscrapers: Pierre LeBrun’s 1909 Metropolitan Life Tower, across the street, and Daniel Burnham's 1903 Flatiron building, a half block west. It jolts the neighborhood into the present." In the New York Observer, Dana Rubinstein was somewhat less enthusiastic. Conceding that the tower was "not ugly", she wrote that the building is "in its overpowering, hubristic way, kind of pretty." Architect Dan Kaplan is quoted on a Wall Street Journal weblog as saying that the building is an "elegant, thin stalk", and represents a continuation of a long-held vision of Manhattan. Kaplan does say, however, that the sliver building "turn its back, a little bit, on the park".
