Kit homes and mail order architecture is a different sort of homogenization than what is happening in suburban America today. During the period of the early 1900s to the 1960s, America was a beautiful hodgepodge of architecture styles, from the midwest’s Prairie school to the beautiful American Craftsman homes of the west coast. The era was also influenced by a series of different mail order architecture from companies like Sears, Bilt-Well Homes, Bennett Better Built, Aladdin and a variety of others. While I am not an architectural expert, I am a known seeker of nostalgia and it is easy to appreciate the American residential landscape from a simpler time.
