The house replaces an old warehouse that was washed out to sea in a storm in 1992. Flood level tides can reduce the islet to half size, so expecting future storms, water can penetrate the ground floor without causing damage.

The main structure consists of seven steel frames, protected by a timber façade with a number of hinged and sliding panels. The inside spaces on the ground floor are bounded by steel and glass walls. On the level above, four timber volumes have been inserted containing bedrooms and bathrooms.

The building was constructed on land at Ulsteinvik, shipped two nautical miles on a crane barge, and lifted into place on the islet.
