IBM Somers Office Complex
The IBM Somers Office Complex is a campus of five office buildings owned by IBM in Somers, New York, United States. Situated on a 730-acre (3.0 km 2) campus, the I.M. Pei designed structures house regional headquarters for the IBM corporation. Described as a "futuristic fortress", the 1,200,000-square-foot (111,000 m 2) complex is an example of modernist architecture.

Viewed from above, one can see the four main buildings and the central service building atop a hill. Each is in the shape of a triangle and is topped with a pyramid of glass. The buildings are located on a campus of 730 acres (3.0 km 2) and in total contain 1,200,000 square feet (111,000 m 2) of office space. Despite job cuts in 1992 and 1999, the plant is still entirely owned by IBM and houses approximately 2,000 employees in divisions such as Global Services, Software, and the Systems Group.

The complex was originally conceived in 1983 following the successful approval of the PepsiCo corporate campus nearby, following an invitation from the supervisor of Somers, Wayne Van Tassell to visit the town. Constructed between 1984 and 1989, the $55 million complex enabled the centralization of 3,000 employees located in other facilities in the surrounding area. Despite initial complaints of excessive water usage and light pollution, the complex has remained a major business location in the Somers area.
