Despite recent reports that that the area's tight real estate market is easing slightly, the fact that nearly a quarter of the office tower's space will soon be available still makes it an appealing investment. One of the building's lead tenants, Palmer & Dodge LLP, will be turning over nearly 150,000 sf when it moves into Boston Properties Inc.'s 111 Huntington Ave next fall. In addition, Holland & Knight LLP will be opening up 50,000 sf in the building when it moves to James Ave.

Westbrook made its first foray into the area a year and a half ago when it bought Allstate Insurance Co.'s portfolio. The purchase included 1030 Massachusetts Ave. The company then bought 265 Franklin St. for $66 million, which it recently sold to Boston Properties Inc. for $98 million. Other purchases include 18 Tremont St., 711 Atlantic Ave and the Davenport Building at 25 First St, with Paradigm Properties.
