One World Trade Center crowned the tallest building in US


One World Trade Center — the marquee skyscraper that has spent more than a decade in development and construction amid great political debate — has claimed the mantle of tallest building in the country, staving off a challenge from Chicago's Willis (formerly Sears) Tower, an expert panel of architects has announced.

The Council on Tall Buildings and Urban Habitat, the official arbiters of all things architectural, said Tuesday that the 408-foot antenna atop 1 WTC counts toward the building's full height.

The decision settles a flurry of debate over whether the spire was integral to the structure's design. The organization does not count "antennae, signage, (or) flag poles" toward buildings' officials heights.

Without the needle, the building stands at a 1,368 feet — rivaling but not eclipsing Willis Tower's 1,451 feet.

Speaking just blocks from the World Trade Center, the council's chairman, Timothy Johnson, said the decision was unanimous among its 25 members.

"It was very clear that it was a spire and not an antenna" at the top of 1 WTC and qualifies as "part of the architectural expression of the building," said Johnson, a partner at global architecture firm NBBJ.

The announcement caps a decade of development and debate around the skyscraper at the World Trade Center, the site of the Sept. 11, 2001, terror attacks.

A year after the attacks, former New York Gov. George Pataki announced that the new structure would rise to a symbolic 1,776 feet.

1 WTC's design went through various fits and starts over the last decade. At one point, an antenna was added that would have vaulted the building’s height to over 2,000 feet, making it the world’s tallest at the time.


A ceremonial cornerstone was laid on July 4, 2004, years before any concrete was poured and when the building was still known as the Freedom Tower.

Blueprints changed several more times in the ensuing years before construction began in earnest in 2006. All along, the officials, architects and developers involved in the politically-charged project maintained that the building would, at the very least, be tallest in the country — and therefore, the hemisphere.

But a little-noticed move in 2012 — the developer's decision to scrap the decorative sheathing that would have made the mast integral to the building's design and therefore an unequivocal "spire" — prompted uncertainty over whether the building could still claim the mantle of tallest in the U.S.

The design change would have saved $20 million on a $4 billion structure.

Rivalry notwithstanding, Willis Tower and 1 WTC are dwarfed by other skyscrapers around the globe. The Burj Khalifa in Dubai, current titleholder for world’s tallest, soars for another 941 feet from the top of 1 WTC’s spire. Another building under construction in Saudi Arabia is set to stand taller than both buildings if they were stacked on top of one another.

But Tuesday’s decision remains a victory for the Port Authority of New York and New Jersey, the supra-governmental agency that owns the World Trade Center site. In a statement, the Port Authority said the council’s ruling “recognizes One World Trade Center’s rightful place in history.”

One World Trade Center is expected to open next year with publishing giant Conde Nast as its main tenant.
