This study examines and analyzes uses, changes, transformation of plane and changes of arrangement of house components with traditional private houses located at Kyideok village, Hanrim-eup, Jejudo and the results of this study are as follows.
First, according to uses of rooms at private houses, the mistress used small room for their daily residence to serve meals and guests as the major residential factor and the master used large room for their residence to perform ancestral rites or to be bedroom for children or guests as the place for main family events. Sangbang (상방) was mainly used for houseworks, resting and entertaining guests, and Chatbang and Gopang were used for meals and storage, but these rooms were often changed for other uses.
Second, sleeping was done in small room, kitchen was used to prepare meals and in summer floor was used as place for meals and in winter small room was used for meals. Small room was also used for entertaining close friends or relatives and large room was for important guests. Small room was used for taking personal rest, large room was used for children's study, and Gopang, Mulpang and Jeongji were used for storage.
Third, according to the changes of space by spatial components, Jeongji was mostly changed into western style from conventional one and Gopang was often placed by dividing the space. Small room was mainly used for enlarging space by integrating other adjacent spaces and in particular, integration of Nanggan on the front was mainly found. Large room also integrated adjacent spaces Nanggan and Gulmuk to increase its area. Gopang and Chatbang were integrated into other space or were not used as their original uses, but they were changed into room or kitchen. As described above, residential spaces were changed into other uses and frequency of changes by room showed small room, large room (22)>Jeongii, Nanggan(21)>Gopang(11)>Chatbang(6)>Sangbang(4) in order, and changes were found centering around small room, large room and kitchen. Major contents included integration and extension of room and security of more rooms and areas through changes of uses, and heating system and western-styled kitchen were developed through the introduction of installation technology and changes for improving functionality of space use and living convenience were made.
Fourth, changes of spatial components such as integration, extension and division resulted in those of plane as well as those of unit spaces. To sum up the types of plane changes caused by changes of spatial components, it can be divided into internal adjustment, additional and mixed types. In case of adjustment plane, change of plane was caused by removal or creation of internal wall and it was found at 10 houses. Additional type was shown as change of "一" letter type plane into "ㄱ" letter or "ㅗ" letter types by attaching room or accessory space to side or back of existing plane and it was found at 1 house. In case of mixed type, internal adjustment and additional types were found together and it was found most frequently at 11 houses.
Fifth, arrangement of house was evenly found as 二-letter type (9), twisted ㄱ-letter type (6), and twisted ㄷ-letter type (6), and main access was made from left and right sides of inner room. Changes of arrangement types showed that attached rooms were divided into addition and removal of attached room, extension of inner room area, new construction of attached room and maintenance of existing structure depending on the increase or decrease of attached rooms to existing arrangement. Location where attached room increases was shown as front (7), left front (7), left (2) and right front (2) based on inner room.
Sixth, changes of spatial components caused those of spatial structure as well as plane shapes. Spatial structures were changed into reduced type of circulation, negligence type which didn't use increased spatial factor and increased type of various circulations with increase of convenience space.
