Frank Lloyd Wright’s historic impact on architecture, including here in the Valley, is far-reaching.

Wright has been in the headlines more than five decades after his death as a battle continues in the Arcadia area of Phoenix about how to preserve a home he designed for his son and daughter-in-law.

There are also some preservation challenges at the Wright-designed Taliesin West in Scottsdale.

Fred Prozzillo, director of preservation for the Frank Lloyd Wright Foundation, explained the preservation battle.
