Nestled among the rich vegetation of Sanibel Island’s gulf coast lies an icon of American modernism. The Walker Guest House, designed by the preeminent architect Paul Rudolph for Dr. Walter Willard Walker, has stood the test of time as a perfect union of function and form. In this episode of Expert Voices, Walker family member Tian Dayton and architectural critic Paul Goldberger discuss the genius of the house’s dynamic design and the enduring legacy of both its creator and patron. Famous soon after it was built, the Walker Guest House was voted one of the most important houses of the century by the readers of Architecture Record in 1957 and will be offered as a highlight of Replica Shoes ’s Important Design Sale (December 12 | New York).
