Ironworks Campus was a heavy manufacturing complex for more than 150 years. The former storage buildings, offices and manufacturing bays have been fully re-imagined into tech, professional and entertainment spaces and are now home to 20+ businesses and more than 1,200 employees.

HISTORY OF IRONWORKS CAMPUS

For nearly 150 years, the site was home to the Beloit Corporation, an economic powerhouse that manufactured the world’s finest paper-making machines. Like many other industries in the region, Beloit Corporation struggled through an economic downturn and ultimately closed its doors in 1999.

In 2001, Ken and Diane Hendricks purchased the property and began a remarkable transformation. Renamed “Ironworks” to reflect its historic roots, renovation of the 750,000+ SF property began in 2002. The former office and storage buildings, foundry, and various manufacturing bays have been fully reimagined into attractive loft-style office and creative spaces. Exposed brick walls and open truss ceilings showcase a unique industrial character.

Today, Ironworks Campus is home to a variety of thriving businesses and a true epicenter for the residential and working downtown community of Beloit.

Ironworks Campus carries a legacy that spans more than 150 years. Once a heavy manufacturing complex, it served as the headquarters of the Beloit Corporation, a company known worldwide for producing the finest paper-making machines. Generations of workers built equipment here that powered the global paper industry and anchored Beloit’s economy. Like many Midwest manufacturers, the company eventually faced industry decline and economic challenges. In 1999, Beloit Corporation closed its doors, leaving behind a massive industrial footprint and a proud history.

In 2001, Ken and Diane Hendricks purchased the property with a vision to restore its vitality. They recognized the potential in the structures and began transforming the 750,000 square foot site into something new while preserving its historic character. By 2002, renovations were underway and the property was renamed Ironworks, honoring its roots in industry and craftsmanship.

The once utilitarian offices, storage buildings, and manufacturing bays were converted into loft-style spaces that celebrate exposed brick walls, open truss ceilings, and industrial detail. This mix of heritage and modern function has created a distinctive setting that attracts a diverse group of businesses.

 

Today, Ironworks Campus is home to more than 20 companies and over 1,200 employees. It has become a thriving destination that blends history, commerce, and creativity. As both a reminder of Beloit’s industrial past and a driver of its future growth, Ironworks stands as a true epicenter for the downtown community.
