The warehouses that characterize the district are mostly six to eight stories high, and about 62 structures on seven square blocks contribute to the district. The predominant form of design is the Chicago Commercial style, but many other styles were built, including Italianate, Queen Anne style, Richardsonian Romanesque, Classical Revival, and early 20th century commercial styles. The warehouse district was in turn associated with the railroad transportation network that was under development at the time, which connected Minneapolis with the rest of the Midwest and the rest of the country. These warehouses were used for wholesale and storage of goods related to milling and manufacturing. The nomination for the National Register of Historic Places states that the district, as a whole, comprises a cohesive district of buildings with a common physical appearance, as well as a common age and original use.
