Elements which are purely Prairie in style include the extensive use of stucco contrasted with dark wood banding. Several later works, such as the Stephen M. B. Hunt House and Robert W. Evans House share similar detail work and employ the same rectangular frames at each corner. The horizontal emphasis created by this banding, as well as the deep overhangs and window groupings is also a hallmark of the Prairie style. The arrangement of rooms in the first floor of the Hills House and extended porches are evocative of the pinwheel shape found in the Ward W. Willits House, Darwin D. Martin House and other works. As Wright broke away from the conventional, rectangular floor plans with the development of his Prairie homes, the hidden entrance also became more common and can be found in nearly every one of his Prairie houses.
