<P> An estimate in February 2007 placed the initial construction cost of One World Trade Center at about $3 billion , or $1,150 per square foot ( $12,380 per square meter ) . However , the tower 's total estimated construction cost had risen to $3.9 billion by April 2012 , making it the most expensive building in the world at the time . The tower 's construction was partly funded by approximately $1 billion of insurance money that Silverstein received for his losses in the September 11 attacks . The State of New York provided an additional $250 million , and the Port Authority agreed to give $1 billion , which would be obtained through the sale of bonds . The Port Authority raised prices for bridge and tunnel tolls to raise funds , with a 56 percent toll increase scheduled between 2011 and 2015 ; however , the proceeds of these increases were not used to pay for the tower 's construction . </P>
