Core and Shell Hydronic Scope
One Vanderbilt is a 93-story supertall skyscraper at the corner of 42nd Street and Vanderbilt Avenue in the Midtown Manhattan neighborhood of New York City. Designed by Kohn Pedersen Fox, the building was proposed by developer SL Green Realty as part of a planned Midtown East rezoning in the early 2010s. The skyscraper’s roof is 1,301 feet (397 m) high and its spire is 1,401 feet (427 m) above ground, making it the city’s fourth-tallest building after One World Trade Center, Central Park Tower, and 111 West 57th Street.
One Vanderbilt’s facade and design is intended to harmonize with Grand Central Terminal immediately to the east. The building’s base contains a wedge-shaped void, and the tower tapers as it rises, with several “pavilions” and a pinnacle at the top. The facade is made mostly of glass panels, while the spandrels between stories are made of terracotta. The superstructure is made of steel and concrete, and the interior spaces are designed to be as high as 105 feet (32 m). The lobby has a bank branch and an entrance to the nearby railroad terminal and the associated subway station, while the second floor contains the Le Pavillon restaurant. Most of the building is devoted to office space, and the top stories contain an observation deck, Summit One Vanderbilt.
