The research carried out during this Double Degree Master thesis deals with the study of morphology and building typology in Chinese countryside, particularly, the Water towns of the Yangtze River Delta. This thesis, like a stool, is based on 3 legs: Chinese Countryside, urban Morphology and building Typology. The first three chapters deal with analysis of Chinese countryside and its transformations from the ancestral to the contemporary period; the study of the history of urban morphology and building typology, applied to the Chinese context; the development of new theories such as the study of Water towns as four elements (water canals, bridges, buildings and streets).
