This report is a study of houses in small towns of Jiang-Nan China. The point is to consider the various plans of houses which are closely related with water. From this study it became obvious that houses show three types. The first type is the courtyard-style houses built on large lots for purely residential use. The second type is the courtyard-style shophouses. The third type is the small shophouses of two stories. The second and third types are found in the commercial areas. The organic urban space of the water towns is formed by these three building types.
