Abstract
A look at the past residential architecture of Iran indicates a lost fact in current houses and its nature and non-existence are resulted from applying the intangible elements with warp and weft of Iranian culture and tradition. Since there was always a moderating pattern in design and building of Iranian traditional houses leading to the functional diversity in accordance with culture,religion and life style of people,the development of industry and penetration of Western architecture has struck out all. This research intends to study the Iranian and Japanese traditional houses and reveal a clear image of how the beliefs are formed in design and decoration of Iranian houses through comparing them with properties of modern houses. The research method is descriptive — historical. At last,to achieve a more flexible and nobler environment,solutions are offered to realize spaces with Iranian identity through combining and coordinating the valuable historical elements with new and modern elements.
