The American System-Built Homes were modest houses in a series designed by architect Frank Lloyd Wright. They were developed between 1911 and 1917 to fulfill his interest in affordable housing but were sold commercially for just 14 months. The Wright archives include 973 drawings and hundreds of reference materials, the largest collection of any of single Wright project. Wright cancelled the project in July 1917 by successfully suing his partner Arthur Richards for payments due and rarely spoke of the program again. The designs were standardized and modular, so customers could choose from one hundred and twenty nine models on seven floorplans and three roof styles. Most materials were prepared and organized at Arthur Richards' lumber yard, so there was less waste and specialized labor needed for construction. Milled and marked materials were delivered to the work site for cutting and assembly by a carpenter. Windows, doors and some cabinetry were built at the yard. Frames, shelves, trim and some fixtures were cut and assembled on site. Most wood parts had a part number and corresponding instructions and drawings for joining, fit and finish. Richards' yard also supplied plaster, concrete, paint and hardware.
