A second-floor amenity deck includes a heated pool, an ovoid lawn, and outdoor dining.

The Regional Workforce Innovation Center houses St. Charles Community College's advanced manufacturing, robotics, energy, and healthcare training.

Corridors and the terrazzo lobby open directly onto the shop floors.

The tenth 21c Museum Hotel occupies a 1926 former YMCA on Locust Street, pairing a boutique hotel with contemporary art galleries open to the public.

Beloit College Powerhouse is a reused coal plant on the Rock River, now a recreation and wellness center. The brick walls, smokestack, and the salvaged turbine machinery have been kept in place.
