About the Walter House
Lowell Walter was an Iowa businessman during the mid-20th century. In the late 1940s he and his wife, Agnes, commissioned Frank Lloyd Wright as the architect for their dream home at Cedar Rock. In 1981, the Walters donated their home to the state of Iowa. The residence lies on a limestone bluff overlooking the Wapsipinicon River and is carefully maintained by park staff.

The Walter House Design
Nearly everything at Cedar Rock bears the imprint of Frank Lloyd Wright. From the entire architectural structure of the house to the interior design, this Usonian style home is one of Wright’s most complete designs. The estate includes the only original Wright-designed boat pavilion still in existence. Iowa is home to ten Frank Lloyd Wright’s structures, and Cedar Rock is the only one with his coveted signature tile.
