Long before designing his signature Usonian houses, Frank Lloyd Wright envisioned an earlier series of affordable models for the middle class: The American System-Built Homes. He developed seven floorplans of varying size and layout, standardized so that materials could be precut at the factory to reduce costs. Only a few years after the project began, the United States entered World War I, and all home construction was stalled due to lumber shortages. Wright then turned his attention to other projects, and with fewer than twenty built, the American System-Built Homes were all but forgotten. Hardcover, 128 pages.
