Early Twentieth-Century Commercial structures are generally one to five stories, with flat or slightly pitched roofs. Often constructed of blond or light colored brick, these buildings have very little ornamentation other than some decorative brickwork along the cornice or parapet. In some of the smaller towns, 20th century commercial structures retain some elements of 19th century commercial structures.
The clear glass transoms of the nineteenth century has largely been replaced by translucent prismatic glass. Some storefront entrances of this period are flush with the façade. Others, particularly in retail establishments, feature deep, nearly façade-wide recesses that allow shoppers to examine window displays out of the sidewalk traffic.
