"To achieve full occupancy in the Alewife market is a testament to the quality of the building and our leasing, management and ownership team," says Albert J. Corr, vice president of Berwind Property Group, which owns the building. Corr worked with David Townsend of Cushman & Wakefield on the deal. Mark Winters, also of Cushman & Wakefield, represented Cambridge Systematics.

The 135,572 sf first-class building, located in the Alewife submarket of the city, was 40% occupied in early 2003. The area had an overall vacancy rate for third quarter 2004 of 17.5%. Lease rates for this deal were not available, but the average asking rent for office space in the area is about $27 per sf.

The building, which is adjacent to the MBTA Red Line Station, was constructed in 1990 and is the newest first-class building in this submarket. Among the current tenants in 100 CambridgePark are Deltek Systems, Cambridge Savings Bank, and Boston University.
