Soon after the September 11 attacks , in 2001 , Silverstein declared his intent to rebuild , though he and his insurers became embroiled in a multi-year dispute over whether the attacks had constituted one event or two under the terms of the insurance policy , which provided for a maximum of $ 3.55 billion coverage per event . A settlement was reached in 2007 , with insurers agreeing to pay out $ 4.55 billion , which was not as much as Silverstein had sought . Silverstein also ran into multiple disputes with other parties in the rebuilding effort , including with the Port Authority . In an agreement reached in April 2006 , Silverstein retained rights to build three office towers ( 150 Greenwich Street , 175 Greenwich Street , and 200 Greenwich Street ) , while One World Trade Center ( previously referred to as the " Freedom Tower " ) would be owned by the Port Authority , as would Tower Five , which it would have the option of leasing to a different private developer and having redesigned as a residential building
