The grain barn was used for threshing, winnowing and storage. Its entrance faces the open courtyard and the gable faces the sea. The building has three rooms side by side. The eastern room has conventional log walls whilst in the two others the middle logs have been replaced by vertical planks fitted into groves on the log below and above. This technique creates ventilation gaps between the planks and is in Norwegian called "skjelterverk". The building is elevated off the ground and the western end rests on pillars. The grain barn originates from Holmenes in Balsfjord.
