The complex will be topped by what the firm titles "one of the largest naturally growing sloped 'green roofs' in North America ... "
It is a 240,000-square-foot roof composed of what the firm describes as a "virtual prairie meadow in the sky."
"The sloping roof and its planting of purple coneflowers, black-eyed Susans and creeping sedum will blend form with function, creating a beautiful 'garden in the sky' that also will reduce rainwater drainage to a minimum. The Aqualand green roof will reduce storm water runoff released into the city sewer system to practically nil."
The roof won't be the only thing unique about the structure. It will have large glass walls that will gather sunlight. Waterfalls and water gardens also are expected to grace the almost 16-acre site.
The building features a 240,000 square foot vegetative roof, which plays a key role in the ecosystem by filtering rainwater that helps keep the facility cool.
