A Chronological Study on the Ctesiphon Residential Houses on Jeju Island

제주 주거용 테시폰의 실태와 공간구성 변용 과정에 관한 연구

Historic preservation efforts are needed to protect the remaining Ctesiphon buildings located on Jeju Island. This study aims to understand the space programming involved and the progression of construction methods used on Ctesiphon residential buildings. Old aerial photographs and an on-site survey helped locate and determine if a Ctesiphon building still existed there. Further analysis of old images revealed enclosure characteristics and interviews were conducted on former and current Ctesiphon residents to understand the built environment of its indoor space. As of 2020, only 37 Ctesiphon system buildings are remaining on Jeju Island. They can be classified into four types of floor plans: a parallel layout, a symmetry layout, a single house with a chimney on the living space side, and a single house with a chimney on the warehouse space side. During an earlier period, buildings had one layer of cladding as an enclosure. Eventually, double cladding was used to combat condensation and provide insulation to it. Over time, improvements on floor plans and technological advances contributed to the development of Ctesiphon system houses and in adapting to the local culture of Jeju Island.
