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. The local framing system called "Sashimono-zukuri" exposes the full shape of large beams called "Sashimono" in the upper part of the main living space "Chanoma". Analyzing the arrangement of "Sashimono" and its supporting elements in relation to the spatial organization of "Chanoma", it's revealed that the reason for applying "Sashimono" is shifting from structural to aesthetic expression. Thus, "Sashimono" is disappearing in some cases, attaining the second floor for living.
