Sal Haaken is an exhibition-hall for the art-collector Haaken Christensens collection, an addition to Henie Onstad Art-Center. The idea of the building is to interpritate the connection between art and nature. Views of the park-area and the harbour near by are intergrated in the hall by large glass area. The landscape-space and the varying light-conditions enhance the art-experience. The construction of massive-wood of birch and larch, has a potential both ecologically and technically benefits. The wood acts as a moist-stabilator.
