Compared to the amount of architectural research in Tibetan sacral buildings only very few describe the rural architecture of the Tibetan people. The central question of this research surrounds the main principles and particularities of vernacular architecture in Tibet. During a field research, important information on local sources was collected. The data served as fundament for the comparison and analysis of the Tibetan houses. The domestic architecture follows certain constructive and functional principles, which are present in the entire cultural area, it follows as well regional construction techniques that adapt to the changing conditions. The static structure and the use of construction materials clearly reflect the dominant climate conditions. An analysis of the room order places the houses in context of their environment and demonstrates their hierarchical structure. In addition, it will be shown which sacral constructive and decorative elements can be found in the simple domestic architecture. Furthermore, the possibility that the structure of Tibetan domestic houses stem from nomadic tents will be elaborated.
