Abstract
The purpose of this research is to clarify the process of transformation in framing of the traditional timber houses in the area of Rokuseicho, Ishikawa prefecture. Focussing on the height of "Sashimono" and girders, this paper analyzed the adjoining system between main frame and roof frame, and revealed two types of transformation. In case of changing roof from thatching to tile, main frame restricted by the original roof span expanded upwards or sideways adding extra girders. In case of tile roof from the beginning, without restriction of roof framing, main frame can be composed of "Sashimono" in various arrangements.
