The sale of 100 CambridgePark is indicative of Berwind's overall strategy of buying underperforming properties, adding value through redevelopment and aggressive leasing, and releasing them to the market. Berwind bought 100 CambridgePark in October of 1997 for $23.5 million and the building was half empty just a few years ago. The firm also acquired the Campus at Marlborough from 3Com in November 2002 for $57 million, when the occupancy rate hovered around 58%. Both buildings are at or near full occupancy now. Berwind's 35 Village Rd. property, renamed Ferncroft Corporate Center, was 57% occupied at purchase, but last week the company leased 55,000 sf to SAS Institute to push it over 80%.

The purchase of 100 CambridgePark Dr. by the family-owned investment and property management company brings its portfolio to seven properties valued at more than $80 million. Transatlantic owns and manages American Twine Office Park, One Mifflin Pl., 271 Cambridge St., and 60 Gore St., all of Cambridge; as well as 130 Forbes Blvd. in Mansfield and Batterymarch Park II in Quincy.

Cushman & Wakefield's Rob Griffin, New England president, Marci Griffith Loeber and Edward C. Maher, executive directors, procured the buyer and represented the seller. C & W's Mark Winters and Dave Townsend are the leasing agents.
