Bursa is a metropolis with numerous villages; the traditional architecture is characterized by masonry ground level walls supporting the timber frame of the upper floors. With the advent of modern techniques and materials, there has been a shift in the construction industry; the traditional character of the villages started to change dramatically. Further damage can be stopped by adoption of systematic approaches. Legal protection is important but lack of technical expertise and financial support results in great losses to vernacular architecture. Recently, public funds and technical assistance have been provided to improve streetscapes and rehabilitate the historic houses in villages. Conservation projects are being guided by local governments. Four historic villages near Bursa were studied to compare the current conservation mechanisms in force and to suggest guidelines for good practice.
