Known as the last Prairie-Style house designed by Wright, the Henry J. Allen House speaks to the architect’s unique horizontal aesthetic, as seen in the roof, brick work and window and furniture details. The house was built during a transitional period, not only for the United States as the nation entered World War I in 1917, but also for Wright and Allen individually. Wright was in the midst of designing and building the Imperial Hotel in Japan while Allen was running a bustling newspaper business -- only to soon become the governor of Kansas in 1919. The Allen House is thought to be the last Prairie style design of Wright's career and embodies the ideals of a "democratic architecture" for America.
