One World Trade Center may not be USA’s tallest


A late change to the design of the One World Trade Center in New York may cost the tower its title as tallest building in the USA.

US media have reported that the 124m needle on the top of the building will no longer be enclosed in a fibreglass and steel enclosure, due to maintenance issues.

The lack of an enclosure may mean that the needle is deemed an antenna rather than a spire, and will not count towards the final height measurement – previously anticipated at 541m.


If the needle is discounted from the measurement, the New York tower will not usurp the title from the 442m Willis Tower in Chicago.

The measurements for tall buildings are determined by the Council on Tall Buildings and Urban Habitat (CTBUH).

A statement from CTBUH read: “At this point, since the building is far from completion, there is no final determination on the height of One World Trade Center.

“A final determination will be made by the CTBUH Technical Height Committee based on analysis of the drawings and other information submitted by the building owner, development and consultant team.”

One World Trade Center recently surpassed the height of the Empire State Building and is due for completion in early 2014.
