The firm will continue to occupy the 33rd, 34th, 35th and 36th floors of the 1.5- million-sf, 39-story building, which is owned by Boston Properties. Studley negotiated the lease for the firm. Studley represented Arnold & Porter in its original lease at the site and also handles the firm's real estate needs across the country. The firm's CEO and chairman Mitch Steir, along with executive managing director Howard Nottingham, executive vice president Matthew Barlow and senior managing director John Mambrino represented the firm. John Powers of CB Richard Ellis handled the transaction on behalf of the owner. Attorney Stewart Offner of Mintz Levin handled legal negotiations on behalf of Boston Properties, while Arnold & Porter was represented in-house by Jennifer Perkins.

Steir notes that the deal fits with the firm's long-term growth projections. "It was important that we were able to lock in future contiguous expansion options with attractive economics." The financial arrangements were not released; however, no direct lease space is currently available in the site.

Arnold & Porter is added to the growing list of law firms taking up large blocks of space. Two international law firms--Hunton & Williams and Gibson, Dunn & Crutcher--inked deals totaling 185,000 sf for office space at the three-million-sf MetLife building at 200 Park Ave. Full-service law firm Heller Ehrman White and McAuliffe inked a deal for 138,000 sf in the 1.2-million-sf Times Square Tower, also owned by Boston Properties.
