Located adjacent to Memorial Stadium, the Irwin Indoor Practice Facility at the University of Illinois Urbana-Champaign provides the football team with the ultimate in flexibility for working indoors or out in response to changing weather conditions. A unique structural approach combining an asymmetrical arched truss spanning lengthwise with conventional gable framing to the sidewalls reduces the scale and impact of the structure on its site and neighboring buildings while still allowing appropriate interior vertical clearances for football activities. Because the site borders the academic district, the exterior of the building uses materials typical to the campus including university blend brick, limestone detailing, and areas of limestone-colored metal panels. The 80,000 square foot facility provides an abundance of daylighting along with indirect/direct artificial lighting and includes retractable netting and batting cages for expanded use by the baseball, softball and soccer programs.
