Book excerpt: The Robie House in Chicago is one of the world's most famous houses, a masterpiece from the end of Frank Lloyd Wright's early period and a classic example of the Prairie House. This book is intended as a companion for the visitor to the house, but it also probes beneath the surface to see how the design took shape in the mind of the architect. Wright's own writings, rare working drawings from the period, and previously unpublished photographs of the house in construction help the reader look over the shoulder of the architect at work. Beautiful new photographs of the Robie House and related Wright houses have been specially taken to illustrate the author's points, and a bibliography on Wright is provided.
