Architects Charles Sumner Greene and Henry Mather Greene began designing craftsman style bungalows in Pasadena, California in 1903.
According to ci.glendale.ca.us the craftsman architectural style encompasses the bungalow, clipped gabled craftsman, cottage style craftsman and colonial craftsman.
By the 1910s craftsman style homes were featured in magazines like "House Beautiful," "Good Housekeeping" and "Ladies Home Journal."
In his book "Identifying American Architecture," John Blumenson describes a typical bungalow as a single story home with broad, gently pitched gables.
The porch is a dominant feature of the bungalow style. According to ci.glendale.ca.us a lower gable typically covers the porch which is supported by heavy columns with battered–or sloped–sides.
Bungalows became an American classic between 1905 and 1940, although they were most popular in the 1910s and 1920s.
