The cost of this complex is an impressive $ 3.8 billion,
according to the WSJ, this figure exceeds $ 700 million the previous estimates,
thus making it considered, as already mentioned, the most expensive office
tower in the world.
Moreover, once built, the One World Trade Center will
be the tallest skyscraper in New York, though not the highest ever, as the Burj
Dubai's Khalifa far exceeds its quota.
The cost of this tower, as revealed, is thrown because of
the adopted strict security systems, also because the One World Trade Center
will replace the Twin Towers.
