 Construction of the new 7 World Trade Center began in 2002 and was completed in 2006 . The building is 52 stories tall ( plus one underground floor ) , making it the 28th @-@ tallest in New York . It is built on a smaller footprint than the original , allowing Greenwich Street to be restored from Tribeca through the World Trade Center site and south to Battery Park . The new building is bounded by Greenwich , Vesey , Washington , and Barclay streets . A small park across Greenwich Street occupies space that was part of the original building 's footprint . The current building 's design emphasizes safety , with a reinforced concrete core , wider stairways , and thicker fireproofing of steel columns . It also incorporates numerous green design features . The building was the first commercial office building in New York City to receive the U.S. Green Building Council 's Leadership in Energy and Environmental Design ( LEED ) certification , where it won a gold rating . It was also one of the first projects accepted to be part of the Council 's pilot program for Leadership in Energy and Environmental Design – Core and Shell Development ( LEED @-@ CS ) .
