The Ward W. Willits House is a home designed by architect Frank Lloyd Wright. Designed in 1901, the Willits house is considered one of the first of the great Prairie School houses. Built in the Chicago suburb of Highland Park, Illinois, the house presents a symmetrical facade to the street. One of the more interesting points about the structure is Wright's ability to seamlessly combine architecture with nature. The plan is a cruciate with four wings extending out from a central fireplace. In addition to stained-glass windows and wooden screens that divide rooms, Wright also designed the furniture for the house.

Frank Lloyd Wright Sr. was an American architect, designer, writer, and educator. He designed more than 1,000 structures over a creative period of 70 years. Wright played a key role in the architectural movements of the twentieth century, influencing architects worldwide through his works and mentoring hundreds of apprentices in his Taliesin Fellowship. Wright believed in designing in harmony with humanity and the environment, a philosophy he called organic architecture. This philosophy was exemplified in Fallingwater (1935), which has been called "the best all-time work of American architecture".
