There remain several archiectural drawings which was made in Chosun dynasty, which are quite different from current drawings. The site plan which is composed of slanted elevations doesn't exhist in Western drawing method. This elevation development method is common in Korea, China, and Japan. These three nations also have a common point which the wooden structure are popular. So elevation development method is reasonable to represent the wooden structure. Because a drawing mehod reflects cultural character and thought, it is important to read the architectural perception at that time. In this viewpoint, I studied the characters of the drawing method in Chosun dynasty according to the peoriodical articulation of century, and how the drawing method reflects the thought at that time. And I suggested a new posibility of effective and reasonable drawing method for the wooden structure.
