Cedar Rock was begun in 1948 and completed in 1950. Wright designed in Iowa. The house is one story and the overall length is about 150 feet. The Garden Room covers more than 900 square feet and has a fireplace which can hold five-foot logs. Glass doors open directly from living areas to ground-level terraces.
Natural light fills the house.
Broad overhangs with upturned edges soften sunlight and shade the glass walls. There are openings in the overhangs covered with vines for summer shade. Recessed artificial lighting creates the effect of natural light, even at night. The Walters were justifiably proud of Cedar Rock. Very little has been altered in the house since its construction and the structure and furnishings are in good condition.
