Poised on a hilltop location is the Dierker house. Its version of the popular white stucco Moderne style lies mid-way between the earlier Art Deco and the later Streamline Moderne. The street facade, consisting of a central two-story block and two one-story projecting wings, is symmetrical, except that this balance is countered by the second-floor balcony that extends to the right. On the garden side of the house, with its view over the Mississippi Valley, are bands of corner windows, an exterior stair leading to a living deck, and a Moderne wall fountain. Other Moderne touches are the steel ship railings, a projecting semi-circular canopy, and angled and arched openings. The architect of the house, Morton Geis, practiced out of Quincy, Illinois.
