'IBM Global Services' by I.M. Pei

1983-1989

Located in Somers, New York, the IBM Corporation Regional Headquarters consists of four office buildings which contain a total of 1,078,000 rentable square feet. Designed by I.M. Pei and completed in the early 1990s, the compound consists of 4 triangular buildings, each 4-5 stories tall, and a "Central Services Building". All the buildings are linked by enclosed walkways, and when viewed from a distance look pyramid-shaped at the top.

IBM sold the property for $31.75M in 2016.
