PROPERTY OVERVIEW

From industrial powerhouse to innovative business center, this property embodies the spirit of reinvention. For nearly 150 years, it was the beating heart of the Beloit Corporation, a global leader in paper-making machinery. When economic shifts forced the company’s closure in 1999, the site stood poised for a new chapter. Enter Ken and Diane Hendricks, who acquired the property in 2001 with a bold vision. Honoring its legacy, they christened it “Ironworks” and set about transforming the vast 750,000+ square foot complex. Since 2002, the property has undergone a remarkable metamorphosis. Former industrial spaces—from offices and storage areas to the foundry and manufacturing bays—have been artfully converted into cutting-edge loft-style offices and creative hubs. The renovation masterfully preserves the site’s industrial DNA. Exposed brick walls and open truss ceilings serve as reminders of its storied past, while providing a unique backdrop for modern business. Today, Ironworks thrives as a diverse business ecosystem, housing everything from engineering firms and golf simulation centers to software developers and e-commerce enterprises. It stands as a living testament to the power of vision, offering a distinctive blend of historical character and contemporary functionality for forward-thinking companies.
