The archaeological excavation showed that the long building measured 83 metres in lenght and 9.5 metres at the widest point. It was most likely erected roughly in 800, during the Carolingian Period/Viking Age. This is the largest building from this period that we know of in the north. The long building, which was built at Borg in 1995, is built on the dugout section, but is adjusted for new use. The building is divided into three main sections with a residential section (5) on the left, the banqueting hall (7) which was the official section of the building in the middle and the section for the livestock on the right.

This cross section shows the earthen walls and the wooden construction which supports the high-pitched roof. The reconstruction of this structure builds upon archaeological finds, the length, width and pole holes were all taken into consideration. Yet the height and specific construction could not be based upon the finds. The main construction builds upon the old construction methods practiced in Northern Norway. The weight bearing poles are connected together with a longitudinal stave line, and are designated by the stave line construction.

The plan- and cross-section illustration was taken from Byggekunst 7/1996.
