Digital River, Inc., is moving its Minnesota operations-including its headquarters-to a single building in Minnetonka mid-next year.

The e-commerce company signed an agreement late last month to lease 132,000 square feet of space from Opus Group-a move that will allow it to house all employees under one roof, Digital River spokeswoman Jennifer Jasinski told Twin Cities Business on Tuesday. The company will move into the building next summer.

Digital River now leases space at three buildings under three separate leases from CSM Corporation and First Industrial Realty Trust, Inc. The buildings together comprise 162,500 square feet and are located in the Golden Triangle area of Eden Prairie.

Those leases will expire next year, so Digital River took the opportunity to try to find a new single location that would be able to house all 650 of its local employees.

Digital River and Opus aren't revealing the financial terms of the lease deal, but the new building is located at 10350 Bren Road West. Completed in 2009, the building was only occupied by its owner for a short time: Opus downsized and reorganized last year after several of its regional subsidiaries declared bankruptcy and shut down.

Jasinski said that the new space was a good fit partly because of the fact that it's in close proximity to Digital River's current locations and partly because it offers “some room to grow in the future.” The building is Leadership in Energy and Environmental Design (LEED) Gold certified, which Jasinski said differentiated it from other building options that the company explored.

Digital River is among Minnesota's 55-largest public companies and is the state's largest Web development and design firm based on revenue, which totaled $403.8 million in 2009.
