"Everyone recognizes Fairfax County as an information technology center, but we also have a strong aviation and aerospace economy, and the addition of AgustaWestland Inc. and AgustaWestlandBell is a world-class addition to that lineup," says Fairfax County Economic Development Authority president and CEO Gerald L. Gordon.

Plaza America I, developed in 1999, sits within the 27-acre mixed-use Plaza America enclave near the Dulles Toll Rd. and Reston Pkwy. AgustaWestland and AgustaWestland Bell will occupy their space at the 10-story facility under a seven-year lease.

Financial terms of the companies' lease agreement with property owner Atlantic Realty Cos. have not been made available. But Marc A. Bassin of Cushman & Wakefield, which handles leasing at the building on behalf of the owner, tells GlobeSt.com that space at Plaza America I is currently being marketed for about $28.50 to $32 per sf. Studley represented the tenant.
