Sokkelvikhuset got its name after its previous location at Sokkelvik. It was moved to Høeghvollen in 1990 when it was also restored. Its exact age is not known but it is assumed to have been built around 1850. The house is now used by the museum, and others, for exhibitions and meetings.

The one and a half storey house has a rectangular footprint measuring 5.3x10.6m, but unlike many typical houses of the era the Sokkelvikhuset has not got the same size rooms on each side of the entrance section. Nor is the main door placed symmetrically, but off centre and right next to the log notches of one of the intermediary wall. On the ground floor there are just two rooms, not at least three as would be expected by looking at the number of corner notches on the southeast side. Most of the eastern intermediary walls has been removed with just the upper logs remaining to carry the weight of the floor and wall above. On the house's northwestern side corner notches have been removed to give room for a second entrance door.
