This study analyzed the transformation of space composition of farmhouse with Kang. The purpose of the study is to show sustainability of traditional farmhouse by focusing on changes of cooking space with Kamado. This paper found that the characteristics of transformation were expansion of the cooking space and separation of part of the cooking space with Kamado. Meanwhile, the laundry space was separated from the cooking space. These transformations were linked with not only improvement of the cooking space, but also Kang-centred living style and two-generation living. We clarified that the systematic change of the cooking space with Kamado contributes to the sustainability of the farmhouse so as to maintain the local living environment.
