MINNETONKA, MINN. — Opus Northwest has received final approvals from the Minnetonka City Council for the construction of Crest Ridge Corporate Center, a 230,000-square-foot, Class A office development located at the interchange of Interstate 394 and County Road 73 in Minnetonka. The first phase of the project will consist of the three-story, 110,000-square-foot Syngenta Seeds headquarters, which will be leased by Switzerland-based Syngenta. The building, which is applying for LEED-Gold certification, will consolidate Syngenta employees from multiple sites in the Twin Cities area. Opus is overseeing the design and construction of the building, which is set to break ground this spring and be complete in mid-2009. Phase II of Crest Ridge Corporate Center will include a three-story, 120,000-square-foot office building, which will also seek LEED certification.
