One World Trade Center Tower in New York is officially declared as tallest building in United States.
World Trade Center building (Freedom Tower) overtakes the Chicago’s Willis Tower(Sears Tower) when an international panel of architects announced that the needle atop the skyscraper can be counted when measuring the structure’s height.
With the needle, 1 World Trade Center is a symbolically important 1,776 feet tall. Without it, the building would have been only 1,368 feet tall — well short of the 1,451-foot Willis Tower.
World’s tallest tower Burj Khalifa, the 163-floor office, hotel and residential building in Dubai is 2,717 feet tall.
The Height Committee of the Council on Tall Buildings and Urban Habitat said the needle is not an antenna but a spire, and thus is a permanent part of the building.
The new World Trade Center tower remains under construction and is expected to open next year.
