Today, AD travels to Phoenix, Arizona, to tour the David and Gladys Wright house—the home designed by architect Frank Lloyd Wright for his son. When your father is America’s most celebrated architect, the greatest gift he could give you is a house, and this unique home uses many of the same ideas Lloyd Wright incorporated in the design of the Guggenheim Museum. The spiral structures, often symbolizing the infinite or longevity, are poetic, as David and his wife Gladys lived to be over 100 years old in this house. After many years of neglect and threats of demolition, father-and-daughter duo Bing and Amanda Hu bought the house and have since been on a mission to restore it to its former glory, keeping its legacy alive.
