The Allen-Lambe House, also known as the Henry J. Allen House, is a Prairie Style house in Wichita, Kansas, designed by Frank Lloyd Wright in 1915 for Henry J. and Elsie Allen. It is currently run by the Allen-Lambe House Foundation as a museum. The house is listed on the National Register of Historic Places. It was one of Frank Lloyd Wright's last Prairie Houses. The design influence of the prairie, and Japanese architecture (Wright was working on the Imperial Hotel in Japan at the time) is apparent on both the interior and exterior. Also included in the forward thinking house were modern conveniences such as a central vacuuming unit, an alarm system and gas fireplace logs. Another innovation of the Allen-Lambe House was the first fire wall in a residential home.
