Former CARADCO Building


The first project in the Dubuque Millwork District is the CARADCO Building, now known as the Schmid Innovation Center/CARADCO Lofts. The Carr, Adams, & Collier Company (CARADCO) Main Plant Building is a former millwork factory in what was, at one time, the nation’s largest window and door manufacturing district.


The Schmid Innovation Center/CARADCO Lofts fills an entire city block and was built between 1880 and 1906. It’s adjacent to Dubuque’s downtown, walkable, working class neighborhoods. By establishing a vibrant mix of residential, commercial/retail, and non-profit tenants, Schmid Innovation Center/CARADCO Lofts creates the “Sense of Place” that exhibits the qualities of true urbanism — density, diversity, energy, and sociability.
