This study is to suggest design types and to identify design characteristics of traditional style public buildings. Since the types of such buildings became very diverse recently, proper classification criteria is essential for future design and evaluation. The demand for such buildings is continuously increasing, but the types of design is very varied; thus it seems important to identify the present design conditions, and to be able to suggest desirable directions for better designs. The research analyzes 31 examples of public buildings in Gwangju Metropolitan City and South Jeolla Province, where there are large number of traditional style public buildings than anywhere else in Korea, and tried to analyzed site plan, elevation, space, details and organizes Design types. This study can help to roughly identify the problems of existing design as well as to suggest improvements in the future design.
