‘In 2009, Scott Bierman, president of Beloit College, in Wisconsin, was on a run along Pleasant Street, at the western edge of the campus. “On my right,” he recalls, “was our 60-year-old field house, a surplus hangar from World War II. On my left was the Alliant Blackhawk Generating Station, which had just been decommissioned. It occurred to me that its interior might be mostly big expanses of space, and I thought, ‘Gosh, I wonder . . .’ ” The result of Bierman’s epiphany is the Powerhouse, a 120,000-square-foot student center focused on recreation and wellness, designed by Studio Gang, and completed last year.’
