WesternBank celebrated the opening of its newly expanded headquarters in Duluth, Minnesota in May, 2007. The design mission for the facility was to update and expand the headquarters to create an eco-friendly, customer-oriented building. The plan included concepts to lessen energy consumption and reduce the use of manufactured materials. Rather than a complete teardown and rebuild, re-usage of existing walls and roofing made it possible to conserve on materials. Inspired by the existing building's Prairie Style of architecture, Shea's designers incorporated many elements of this style in the new design. A band of windows running the entire perimeter greatly increases natural lighting, and other conservation efforts include superior insulation and extensive landscaping.
