Minneapolis Grain Exchange

Minneapolis, Minnesota

The Minneapolis Grain Exchange is a set of three interconnected structures built between 1904 and 1928.  Each structure is an excellent example of commercial design at the beginning of the twentieth century, and is significant as well for its use of early “highrise” masonry construction.


We have worked on many projects at the Grain Exchange (including our own offices), most notably the adaptive reuse of the former trading floor, where active trading ended in 2008. MacDonald & Mack was the architect for the subsequent restoration and rehabilitation as it became CoCo (now known as Fueled Collective), a coworking space for IT start-ups and other small businesses. The project has been featured in many publications, including USA Today, Minneapolis Star Tribune, Inc, St. Paul Pioneer Press, Finance & Commerce, Mashable, Engadget,  and Twin Cities Business Journal.
