This Study deals with the transitional process of collective dwelling units in the Korean Autonomous Region in China. The main focus is the change from the traditional Korean dwelling culture to the modern Chinese context. The analysis was conducted on forty-eight unit plans used during the last four decades. Influenced by the socio-economic situation of China, the plan transformed due to the increase in the occupied area and the change in the heating system from the traditional Ondol to modern heating systems. The transitional process, illustrated using justified access graphs, could be represented by four major plan types.
