The David and Gladys Wright House in Phoenix, Arizona, was built from 1950 to 1952 as a family commission by Frank Lloyd Wright for his son David and daughter-in-law Gladys. One of Wright’s few surviving buildings in Phoenix, it is notable for its organic design: a circular concrete house raised on seven piers, entered by a spiraling ramp and wrapped in a 270-degree arc around a courtyard with a pool. Curved interiors, built-in mahogany furnishings, floor-to-ceiling glass, and a conical fireplace carry the geometry throughout. After threatened demolition following Gladys Wright’s death, preservation efforts saved the house, and a 2020 renovation returned it to residential use.
