For my last day in Phoenix, I had the pleasure of visiting the Southwest home of famed architect Frank Lloyd Wright. Built in 1937, Taliesin West is a UNESCO World Heritage site and one of my favorite subjects of study in Architectural History class in college. Wright designed everything in the home, from the floor plan to the furniture to the lamp shades. While the design is striking, many of the materials used proved frail. For example, the cotton sheets used for roofing are now protected by plastic panels due to the destructive desert sun.
