Mill City Museum
Minneapolis, Minnesota
Renovation and Adaptive Re-use

LKPB completed mechanical and electrical design services for the award-winning historic renovation of the Washburn Crosby 'A' Mill. The Mill stands at the historic epicenter of what was once the largest flour mill in the world. The original A Mill, built in 1874, was destroyed in a flour dust explosion, and it was rebuilt in 1880, operating until 1965. The unused structure was substantially destroyed in a 1991 fire, but the unique renovation has become a wonderful attraction, the Mill City Museum. It offers exhibitions, classrooms, gathering and event space and a Flour Tower ride that transports visitors through a cross-section of the milling process.

The Museum encompasses 45,000 SF of space in the lower three floors and an additional 10,000 SF of outdoor exhibition space in the adjacent Ruins Courtyard. It is located along the historic Mississippi Riverfront.

The Mill City Museum project was honored by these awards:

  • 2003 Preservation Alliance of Minnesota Honor Award
  • 2003 Minnesota AIA Honors Award
  • 2003 Minneapolis Committee on Urban Environment Award
  • 2004 Minneapolis Heritage Preservation Award, Historic Reuse
