The original 7 World Trade Center, a 47-story building with a red granite facade, opened in 1987. Debris from the Twin Towers damaged it on September 11, 2001, and it collapsed soon after. David Childs of Skidmore, Owings & Merrill designed its replacement for the developer Larry Silverstein. Construction began on May 7, 2002, and the building officially opened on May 23, 2006, at a cost of $700 million.
It rises 741 feet (226 m) with 52 stories. The steel frame was erected before the concrete core, which shortened the schedule by a few months. The core has 2-foot-thick shafts, wider stairways and thicker fireproofing. The first ten floors hold a Con Edison substation behind an 80-foot shell of stainless steel louvers. The facade uses ultra-clear glass and stainless steel.
The narrower footprint allowed Greenwich Street to be restored. It has LEED Gold certification and a Jenny Holzer lobby installation.
