Abstract
In this paper I explained the characteristics and the developmental process of the town houses in Sonobe, an old castle town by studying mainly the transformation of structures. In addition. I considered the consequence by comparing the town houses near there with the farm houses around there. The summery of this study can be given below. 1) The front gabled town houses are relatively older than the side gabled town houses, and the original structural forms are the same as the farm houses in Settsu and Tanba area. 2) I realized that the side gabled town houses were derived from the front gabled town houses, because the structures of the side gabled town houses were similar to that of front gabled town houses. 3) Both front and side gabled town houses in an old castle town developed, being affected by the farm houses in Settsu and Tanba area. 4) I recognized that the form of the town houses in Sonobe, an old castle town was the form of the town houses in wide area including Kameoka, Yagi, and Syuchi.
