This paper tries to clarify the formation of old town houses distributed over Yamashiro, Settsu, and Tanba. The style of these town houses is featured by having the entrance on the gable side. Mr. Kuroda argues with Mr. Oba on this formation connected with structure. But I points out that this type had been formed with modeling on‘Hafu’(the triangle board on the gable side on the roof) by the investigation of pictures and architectural regulations with using Hafu. This opinion holds the same view with Mr. Norio Nagai.
