One Worldwide Plaza is the largest tower of Worldwide Plaza, a three-building commercial and residential complex in the Hell's Kitchen neighborhood of Manhattan in New York City. Designed by David Childs of Skidmore, Owings & Merrill (SOM), One Worldwide Plaza is an office building measuring 778 feet (237 m) tall, with an alternative address of 825 Eighth Avenue. It is the easternmost building in the Worldwide Plaza complex, which occupies the entire city block bounded by Eighth Avenue, Ninth Avenue, 49th Street, and 50th Street and is built on the site of New York City's third Madison Square Garden. Adjacent to One Worldwide Plaza to the west are a public plaza and two residential buildings.
The classically inspired building contains a three-story granite base, a brick midsection with setbacks, and a pyramidal copper roof with a glass lantern. Inside, there are storefronts and entrances to the New York City Subway's 50th Street station, while three double-height lobbies lead to different sets of office floors.
Worldwide Plaza was developed in the late 1980s by a syndicate led by William Zeckendorf Jr. Upon opening, One Worldwide Plaza was nearly fully occupied, with two anchor tenants: advertising agency Ogilvy & Mather and law firm Cravath, Swaine & Moore. During the mid-1990s, the office space was leased at a very low price. The Blackstone Group acquired the complex in 1996 and sold it to Equity Office Properties in 1998. When Blackstone took over Equity Office in 2007, it sold the office building to Harry Macklowe, who lost the building to foreclosure. George Comfort and Sons took over One Worldwide Plaza in 2009. American Realty Capital New York bought a controlling ownership stake in 2017, selling off a non-controlling stake to RXR Realty and SL Green Realty.
