The dwelling house underwent drastic changes in 1909-1910. It was expanded and the exterior was modified and given a Swiss style, which was a more stylish appearance at that time. This building is a typical example of wooden architecture that characterised Vadsø before the destruction of World War II.

It is a one-and-a-half-storied building with a saddle roof. On the roof there are three south facing dormers, one large and two smaller ones, overlooking the sea. While a bay window is adjoined to the building on the west side. The house has characteristic elements in the Swiss style: a parapet panel on the lowest part of the wall, window frames, large projecting slate covered roof and richly designed details on the moulding at each floor division.
