This paper is a trial about architectural regulation and order with town house which is two stories high.

But there is possibility of these houses have lumber room in the ceiling which called “tsushi-nikai”. Tsushi-nikai is low ceiling, but in occasionally used for sleeping room and others. In 17th century, Toyotomi government gave order for town people to build two stories for townscape. So that, town people have stated to put on eaves in front of their town houses. As the result of that, low and two stories style have established and called for tsushi-nikai.
