Some critics worry that now is not the right time to spend $975 million on a stadium, but HKS has designed the 65,000 seat structure as a multi-purpose building that can be used for a variety of events. Most of the transparent roof will be made with ethylene tetrafluoroethylene (ETFE), which will allows athletes and spectators to see the sky above without spending millions on a retractable roof.

Framed with metal and wrapped in glass, the stadium also features four operable 95 foot glass doors that open to the public. Climate control and energy conservation, geography, history and technology were driving considerations for the design, which will now be presented to the Minneapolis Stadium Implementation Committee and the City of Minneapolis for review.
