The objective of this study is to identify the formal and structural characteristics of a traditional house type the high ridge-house “Rumah Bubungan Tinggi (RBT)” in South Kalimantan, Indonesia and the process of conserving it as cultural heritage. The RBT is a traditional style of Banjarese house, which has changed in response to the development of social groupings. RBT in urban areas are clearly different from those in rural areas, and reflect differences of local environment, lifestyle and industry. We investigated a total of 13 RBTs (4 RBTs in 1 urban area and 9 RBTs in 2 rural areas). We introduce the general principles of RBT design, then analyze the floor plan, side elevation, and construction techniques. We present an evaluation of the RBT of South Kalimantan as cultural heritage and a framework for understanding the relationship between the houses of the three areas investigated.
