Cedar Rock State Park

Cedar Rock is a residence and museum situated within a state park, built in 1950 on a peninsula overlooking the Wapsipinicon River. The single-story building has an unusual shape with concrete roofs, brick walls, extensive glass panels, and walnut finishes throughout, creating spaces that blend interior living with the natural landscape.

The residence was completed in 1950 as an expression of Wright's Usonian design philosophy, creating affordable modern homes for everyday people. The original owner Lowell Walter and his wife Agnes transferred the property to the Iowa Conservation Commission in 1981, preserving it for public visits.

The residence embodies Wright's approach to domestic living, where indoor spaces flow naturally toward the river views and landscape. Visitors can observe how the building was designed to make the natural setting a central part of everyday life.

The site is accessible by car with parking available for visitors planning to join guided tours of the building. Advance registration is required to visit, so check availability beforehand and arrive early during peak seasons to ensure a spot.

One room features three glass walls facing the river and a large fireplace designed for substantial wood logs, making it feel like sitting at the edge of the landscape. This space demonstrates how Wright extended the home into the natural surroundings through thoughtful design.
