America's largest city once again hosts America's tallest building.
At 1,776 feet, 1 World Trade Center is officially the tallest building in the United States.
The Council on Tall Buildings and Urban Habitat announced the judgment Tuesday, ruling that the Lower Manhattan skyscraper is taller than Chicago's Willis Tower. That building, formally known as Sears Tower, measures 1,450 feet tall.
The Freedom Tower's long mast complicated what appears to be an obvious height discrepancy. Without it, 1 World Trade Center would only be 1,368 feet.
The building's chief architect David Childs, of Skidmore, Owings & Merrill LLC, had to prove to the council's Height Committee that the mast was an expressive design element. He argued last week that the mast brought the building to the symbolic height of 1,776 feet.
"We were very satisfied with the detailed information presented by the team, in particular, that which affirmed that the structure on top of the building is meant as a permanent architectural feature, not a piece of functional-technical equipment," the council's chairman, Timothy Johnson, said in a statement.
"The design of 1 World Trade Center, as explained to us, reinforces its role as a symbol of resurgence on this important site," the council's executive director, Antony Wood, said in a statement.
