CINCINNATI (AP) -- A family in Cincinnati is selling their Frank Lloyd Wright-designed home for $1.78 million.

The house has been in Gerald Tonkens' family since 1955 and is in "pristine" shape.

Tonkens, a car dealer, was 35 years old in 1953 when he asked Wright to build the home, even sending plans to the famous architect at his Taliesin West studio in the Phoenix suburb of Scottsdale.

The Cincinnati Enquirer reports (http://cin.ci/YMAqfZ ) that Wright was in his mid-80s and building what he called Usonian homes for "common" American families at a prolific rate.

Tonken's wife, Beverly Tonkens, says Wright invited her husband to Taliesin West and offered to build a concrete home in a style he developed known as Usonian Automatic.

The home was finished about two years later, and the Tonkens have lived there since.
