During the period of economic growth in the 1970s, the Building Standards Act of 1950 made the traditional methods of construction illegal despite the systems of fuchi-chiku (landscape area) and bikan-chiku (aesthetic area) established before World War II; and consequently, during the bubble years when many of the houses were rebuilt, the streetscape of Kyo-machiya or traditional Kyoto town houses were destroyed.
また1970年代の経済成長期には、戦前からの風致地区や美観地区などの制度にもかかわらず、1950年に制定された建築基準法により伝統工法が違法となり、バブル期には多くの建替えにより京町家による街並みが徐々に壊されていった。
