In this research, we explore and clarify a traditional life phase of the Hanok (Korean-style house) by looking into an autobiographical novel called “The House with a Sunken Courtyard”. The novel describes a family and a society according to a life style in the Hanok during the postwar period (Around 1950s). Through this novel, we are able to prove a life phase of the Hanok which cannot be verified by the current building structure. Moreover, we investigate a relationship between the house and the yard by focusing on some characteristics of the inner and outer spatial structure which has been selectively carried on to the Hanok.
