There are a few hundreds of Jaesil architectures in Andong area, Kyungbook Province. Among them, about 25 of them have elevated pavilion, while all the rest do not have. This paper focus on these jaesils with elevated pavilion, and tried to identify the different types among them, the background of the beginning of these jaesils, as well as eleveted pavilion. Five different types could be clarified, and they could be reinterpreted according to the background cause of the construction of these types. Three major background reasons for the construction of jaesils with elevated pavilion, seems to be: 1) necessity of such pavilion to be able to clomplete the system of Jaesil, 2) borrowing of temple structure where there is not large wooden floor, and 3) eclectic combination of pavilion and main hall (Gangdand 講堂). Such study helps us understand not only the jaesils with eleveted pavilion, but also the general jaesils without eleveted pavilion. The inclusion of eleveted pavilion has a lot to do with the symbolic expression of the family, use of large space for the family gathering, as well as the popular trends of pavilion architecture of the time.
