The southermost complex consisted of three buildings: hall A, house, house B, and hut C.
Hall A
The hall was very large, 29 m long on the outside and with more than 1000 square feet of room inside. This is double the size Erik the Red's hall in Iceland.
The hall had three rooms, in which people lived, slept and ate, rooms I, II, and IV. All these rooms had a substantial fireplace. The smallest room, II, was probably for one of two leaders on the site and his closest companions. People slept and sat on wooden platforms along the walls. Room III was a workshop where iron was forged into objects, probably boat nails. The iron made in the furnace across the brook was heated over a hot charcoal fire in a pit, then worked on an anvil set into a tree trunk close to the fire.
A cloak pin of bronze was found in the firepit.
House B
House B had a wooden platform along one wall. Iron workers lived here, and bog ore had been roasted on the floor. The fireplace was by the southern wall. The wall was protected by an upright stone.
Huts C
Hut C was the most primitive dwelling on the site, with no special arrangements for seating or sleeping. People must have slept on straw directly on the floor. It has the same kind of fireplace as in House B.
