Ranch style housing evolved from several other twentieth century styles, including Prairie school, Bungalow, Cottage and Spanish. Traditional Ranch homes reflect a hard-working, simple life and are often considered a expression of the informality of Western culture. Because these homes are uncomplicated, critics often say the Ranch style has no style. The style is also dismissed because it has become so common. "Ranches" are found in the suburbs throughout North America, making the style synonymous with the concept of tract housing: fast-built, cookie-cutter homes. The first Ranch home, designed by Cliff May, was built in San Diego, California in 1932. Over the next 20 years, thanks in part to the popularization of the automobile, Ranch-style houses spread to other states and were the dominant home style of the 1950s and 60s. Today, many new homes have characteristics of the relaxed, informal Ranch style.
