This paper examines the developments of dwelling in the downstream area of the Nakdong River during the Proto-Three Kingdoms Period. In the middle of the 2nd century BC, the period of the 2nd century AD was divided into three stages according to the advanced years suggested by advanced researchers. The first stage is the second stage of the first century BC, and the second stage is the second stage of the second century BC. The third stage consisted of the earthenware pottery as the second century. The area was mainly located in Gimhae, Changwon, and Busan, which are located in the lower part of the Nakdong River, and the relics were set up in a residential area located about 5 km from the tomb site. As a result, the selected dwellings are located in 12 places, and the steps are set up referring to the earthenware excavated from the dwellings and tombs. Residential areas classified by phase were analyzed for attributes by location type, plane type, fire facility, and Columna layout and were derived using a combination of time-specific plane forms, fire facility and Columna layout. The type is set for the following types of dwellings : ‘A-a-ㄱ, A-a-ㄷ, A-d-ㄱ, A-d-ㄷ, B-a-ㄷ, B-b1-ㄷ, B-d-ㄷ ’. A local review of the dwelling corresponding to III stage was attempted. As a result, it was found that fire facilities differed and generally preferred wall columna arrangements. The development of the dwelling by level was examined by referring to the natural environment, nearby sites, and documents. The dwelling was located in the hills around the coast and the river to ensure safety, but it seems to have grown by touching the new culture through communication with others.
