Book excerpt: American Houses is a historical guide to the architecture of the American home. While other architectural field guides show only façades, this book includes floor plans, showing how the form of a house arises from its function. Photographs and drawings of exteriors illustrate the significant field marks of each style and help pinpoint the key elements that can identify a house even when it has been remodeled beyond recognition. Beautifully illustrated, clearly written, and impeccably researched, American Houses is an essential reference for anyone interested in the history of American residential architecture.
