About This Building
The first fully realized Prairie house — a pivotal moment in architectural history.
The Frank Thomas House is often cited as the first fully realized Prairie house — the moment when Wright's ideas about horizontal space, low-pitched roofs, and the integration of interior and exterior coalesced into a coherent style. The house sits on Forest Avenue in Oak Park and is a private residence, but its exterior is one of the most studied in American architectural history.
