THE HEADQUARTERS · ARMONK, NEW YORK
Stainless steel in the woods
IBM moved its headquarters out of Manhattan to Armonk in 1964, onto a former apple orchard it had bought in the 1950s. The first building, by Skidmore, Owings & Merrill, is now called North Castle. The current headquarters, designed by Kohn Pedersen Fox and finished in 1997, is a 283,000 sq ft building of glass, stone and machined stainless steel on a 25-acre parcel, with the Gerstner Center for Learning nearby.
