Boston Sports Club is leasing 58,000 sf on the first floor of the building for a 15-year term. Bob Fitzgerald of NAI Hunneman represented the tenant in the deal, while Bob Doherty, vice president of brokerage, and Steve Faber, vice president of asset management, both of the Beal Cos., represented property owner Harvard University.

In the second deal, BR+A Consulting is leasing 58,000 sf on the second and third floors of the building. The company is relocating from Soldiers Field Road in a substantial increase in its space. Doherty along with Peter Nichols, senior vice president and partner of the Beal Cos., represented Harvard in the transaction and procured the tenant.

When Harvard bought the 770,000-sf Arsenal nearly three years ago, Arthur D. Little had a master lease on 311 Arsenal, thinking it would ultimately use the space for its expansion. The company subleased most of the space to a number of dot.com companies but eventually ADL went bankrupt before it ever occupied the space itself.
