The International Information Center for Structural Engineers

The Council on Tall Buildings and Urban Habitat announced Tuesday that One World Trade Center is now the tallest building in the United States, at 1,776 feet tall. Previously the tallest building honor went to the Willis tower in Chicago, IL, which stands 1,451 feet tall. The debated issue was whether or not the mast atop the new WTC building should be counted toward the architectural height. The council decided that since the 408 foot spire is a permanent architectural fixture, and not used for technical purposes, its length would be added to the total height of the building, therefore making it taller than the Willis Tower.
