The Songgungni-type dwelling has an oval hollow structure and is one of the residential types in the Bronze Age, in which beams are supported by setting the central post at the inside and/or outside of an hollow and the shape of roof is of facing together form. Judging from the aspect of artifacts, it is very likely that the oval pit is similar to a storage depression. In some regions, the production of stone tools were carried out based on it. Moreover, it is estimated that it played a role as a fireplace for storing kindling charcoal. The residential pattern is divided into four types according to the oval hollow and arrangement form of the central pillar, and subdivided into eight sub-types in terms of the existence of four pillars; A①), A②, B①, B②, C①, C②, D①, D②. The distribution of the Songgungni-type dwelling is divided into five areas. In the midwest plain region Type A① is adopted overwhelmingly. A residential pattern showing the square plane form is found and also demonstrates earlier aspects in piled relation to circular residential districts In Kum river region all eight residential types appear and form the most varied residential culture. Type A① takes up most of them and shows an aspect in which Type A② decreases relatively compared to the midwest plain region. The distance between central pillars reveals the regular aspect as opposed to the midwest plain region, and is also verified as extending aspect somewhat in some areas. An oval hollow shows the feature as a storage pit and some tend to be fireplaces. In Youngsan river district Type A① takes up the area for the most part, and only D① is partly found so that it shows most simple residential pattern. In this place the oval depression also displays the feature of the storage pit but it is verified that there tends to be fireplaces in some areas. Type A forms the mainstream but it shows that Type D is increasing in relation in Boseong river district. The distance between central pillars takes on a dispersing aspect without a set pattern. The oval hollow shows the feature of the storage pit. However, vestiges of acts related to stone-tool production are verified at the circumference of the hollow in numerous area so that it manifests similar aspects in comparison with the Nam river basin. The Hwang river district among the Nakdong river basin maintains the distance between the same central pillars in Type A① and is constructed with Type C① because of the influence of the Kum river basin district. As Type C① of this region is spreading gradually, central pillars form regular distance distribution. In the Nam river basin Type A① is decreasing relatively, on the other hand, Type C① is being built intensively, and also Type D② is adopted in the lower part of the Nakdong river.
