Cedar Rock State Park is astate park inBuchanan County,Iowa,United States, preserving theFrank Lloyd Wright-designedLowell Walter Residence, also known asCedar Rock. TheUsonian-style house was constructed on a bank of theWapsipinicon River nearQuasqueton, Iowa, in 1950. Following Lowell Walter's death in 1981, the home was donated to theIowa Department of Natural Resources and opened to the public.[1] In 2025, the Friends of Cedar Rock received a $50,000 state grant to finance the house's restoration.[3][4]
The Walter House at Cedar Rock is one of Wright's most complete signature designs. Nearly everything at Cedar Rock bears the architect's imprint. Wright designed the furniture, chose the draperies, and even picked out the accessories.
Cedar Rock is an important example of the Midwestern residential style created by Wright, characterized by its provisions for living simply and in harmony with nature. The Walter Residence is an example of a simplified style Wright called “Usonian". These designs were typically created as a single story with zoned areas for living. Wright accomplished this by designing this home in a "tadpole" shape.[5]
