I do not have hard facts but based on my experience, the technology probably: Traveled from east coast to west and from cities out to the countryside Was influenced by the Wars and the Depression Depended on the practitioner (carpenter) and availability of materials and lengths required - balloon framing requires longer lengths of studs. Bottom line you probably can not put a date on it. Around NYC and the northeast platform framing became common after WW II.
