Book excerpt: During the first four decades of the twentieth century, prefabricated and catalogue homes grew in popularity and number. Built and occupied by farmers, merchants, the new armies of factory workers and other lower- and middle-class families, these are the modest homes that today line American streets. Using mail-order house catalogues from the time, Robert Schweitzer and Michael W. R. Davis chart the development of catalogue houses and their variations and include floor plans for many models. Students of architecture, whether amateur of professional, preservationists and academics will find in America's Favorite Homes a handy reference to those homes that soon will be eligible for historic designation.
