The building's rooftop parapet, known as the Freedom Tower, will be 1,368 feet tall, the same as the original One World Trade Center. However, when all 104 stories of the new building, including the antenna, are completed, One World Trade Center will be somewhat taller than its predecessor. The spire on top of the One World Trade Center redesign will be 441 feet high, making it the tallest free-standing spire in the world.
When the Twin Towers were destroyed on September 11, 2001, they were the highest buildings in New York City. The Freedom Tower will be one floor higher than the former World Trade Center hub, which was itself one floor higher than Two World Trade Center. The spire on Top of the Hub will be one floor higher than that at One World Trade Center.
The Freedom Tower is being built by the Durst Organization and designed by Gensler with Arup for the Port Authority of New York & New Jersey. It will house government offices, but also include retail space and a conference center. The building is expected to be completed in 2014.
One World Trade Center is being built by Tishman Speyer and designed by Cesar Pelli with Skidmore, Owings & Merrill LLP. It will be the first U.S. skyscraper to achieve "Platinum" status from the Green Building Council. It is scheduled for completion in 2014.
Although it is located behind New York City's World Trade Center Freedom Tower, it is really significantly taller when considering simply livable space because it lacks any kind of spire. In instance, the Freedom Tower includes a 408-foot spire that adds to its height, whereas the Guangzhou CTF Finance Center would be 371 feet taller without it.
The Freedom Tower was designed by Daniel Burnham and Edward Durell Stone and developed by Silverstein Properties. It was completed in 2003 at a cost of $100 million. The world's tallest free-standing structure for nearly 10 years, it is now ranked as the second tallest building in New York City behind One World Trade Center (471 feet).
The World Trade Center complex consisted of two 110-story skyscrapers plus an underground mall. The 1,776-foot South Tower was completed in 1994, while the North Tower was finished two years later at 1,443 feet tall. Both buildings were owned and operated by WTC Corp., a subsidiary of Boston-based Liberty Mutual Insurance Company. The North Tower was also home to the International Air Response Co. facility, which provided emergency medical services to aircraft.
After 9/11, both towers were severely damaged during multiple terrorist attacks. The North Tower was eventually demolished on March 19, 2007. The South Tower was renovated and has become New York City's new headquarters for AXA Insurance. It opened in 2016 after being delayed for more than a year due to construction challenges including worker fatalities.
The supertall tower bears the same name as the North Tower of the first World Trade Center, which was demolished in the September 11, 2001 terrorist attacks.

However, those on the 1,451-foot Willis Tower are considered antennas, which the council does not count when assessing a building's height. The 408-foot-long pole on 1 World Trade Center, on the other hand, is intended to be more than simply a way of enhancing radio communications, according to its designers. It is there to support the heavy antenna systems used by television broadcasters that need clear air above their buildings to send and receive signals.
The 1,451-foot-high Willis Tower contains 87 stories plus a penthouse apartment. It is now the second tallest building in Chicago after the 1,719-foot Trump Tower. The Willis Tower was built as a luxury hotel but has been managed by Hilton since 1990. It is named after investor J. Irwin Willoughby who also funded construction of the original Yankee Stadium in Bronx, New York.
Willis Tower is also the name of a popular 36-story high-rise near the center of Dallas, Texas. It is one of only two skyscrapers over 700 feet tall in that city (the other is One Shell Plaza). Built in 1974, the Willis Tower is the third-highest building in Dallas/Fort Worth and is part of the U.S. office building complex DFW International Airport. The tower's owners, CIM Group and Madison Marquette, hired Chicago-based architects Henry Cobb & Associates to design the building. They also designed another Chicago landmark, the John Hancock Center.
