The Thomas house, completed in 1901, is widely considered Wright's first Prairie Style home in Oak Park. It is also his first all stucco home in Oak Park. Using stucco instead of wood meant that Wright could design clear, geometric forms. The main rooms of the Thomas House are raised a full story above a high basement. The L-shaped floor plan of the house gives it an open view to the north and west, while obscuring a brick wall located on the south side. A "false door" is located just above the arched entryway.
