1000 Washington St. was formerly the world headquarters of Teradyne Corp.

BOSTON-Behavioral healthcare company ValueOptions has signed on for 39,385 square feet of regional headquarters space at Nordblom Co.‘s 10000 Washington St. here. The new tenant is consolidating several area offices. Lease terms were not disclosed.

A CBRE New England team which exclusively handles leasing at the 242,000-square-foot office tower—EVP and partner David Fitzgerald, SVP and partner Bill Crean and client services coordinator Kristen Jensen—represented Burlington, MA-based Nordblom. The Ezra Co.‘s Lawson Wilder represented ValueOptions, which is headquartered in Norfolk, VA.

At one time the world headquarters of Rustcraft Card Co., at the time the world’s largest greeting-card maker, 1000 Washington sits at the confluence of a considerable amount of development activity nearby. The former Boston Herald building across the street on Harrison Avenue is undergoing a $200-million redevelopment into the Ink Block apartment complex, which ultimately will include 85,000 square feet of retail space. Also undergoing construction is a two-building residential complex at 275 Albany St., which is scheduled to break ground this fall.

Built in 1910, 1000 Washington was also known as 321 Harrison Ave. It was owned and occupied for several years by Teradyne Corp., which had acquired the property as its world headquarters. It had been vacant for about two years when Nordblom acquired it in 2009.
