Photos Help Architect See a Problem

In 1952 architect Frank Lloyd Wright built a spiraling cement-block house in Phoenix, AZ, for his son, David. When it was complete, Pedro E. Guerrero photographed the interior and exterior. Wright was troubled by the constant circulating that he saw in the photos, but hadn’t seen on the original drawing board. The architect came up with a solution. The story is told by Guerrero, who worked with Wright for years.
