The Allen House in Wichita, Kansas, is a remarkable example of Frank Lloyd Wright's Prairie Style architecture. Designed in 1915 for newspaper publisher Henry Allen and his wife, Elsie, it represents the culmination of Wright's prairie houses with its emphasis on horizontal lines and a harmonious blend of interior and exterior spaces. The house is notable for its living room, considered one of the great rooms of the 20th century, and features original Wright-designed furniture and art glass. Now open to the public, the Allen House stands as a testament to Wright's philosophy of organic architecture and his innovative vision for residential design.
