Facebook has just leased enough new office space in Manhattan to nearly triple its current local work force, including at one of the city’s most iconic buildings, the 107-year-old former main post office complex near Pennsylvania Station.
Apple, which set up its first office in New York a decade ago, is expanding to another building in Manhattan. And Google and Amazon are stitching together corporate campuses in the city more quickly than anywhere else in the world. Amazon paid roughly $1 billion in March for the iconic Lord & Taylor building on Fifth Avenue.
