Change to top of WTC raises questions over height

NEW YORK — A change to the design of a needle that will sit atop One World Trade Center is raising questions over whether the building will be America’s tallest when completed.

Developer Douglas Durst said the 408-foot-tall needle will no longer be enclosed in a fiberglass-and-steel structure called a radome. Mr. Durst said the enclosure was removed from the original design because it would be impossible to maintain and repair.

Without the enclosure, it’s unclear whether the needle is an antenna or a spire. That’s important in measuring the building’s height.

If the needle is considered an antenna, One World Trade Center would be smaller than the Willis Tower in Chicago - and lose its crown as the tallest building in the U.S.
