A new building stands out from the rest in New York City's skyline.America's largest city is known for its many extremely tall buildings, also known as skyscrapers.The newly completed Steinway Tower is not New York's tallest.But it is the skinniest, meaning very thin.The 84-story Steinway Tower is a housing structure.It was designed by New York building company SHoP Architects.The project was started in 2014 and completed earlier this year.The building is being called the "most slender skyscraper in the world."This is because it has a width-height relationship, or ratio, of 1-to-23 1/2.Gregg Pasquarelli is a founding member of SHoP Architects.He told The Associated Press that any time a building has a 1-to-10 or more ratio, it is considered a slender building.He said anything 1-to-15 or more is considered "exotic" and "really difficult" to build.
