Housed in a former school building, the museum collection documents the origins of Danish art in the 20th century. In 1999, when the museum acquired Bjørn Nørgaard’s tapestry sketches, a decision was made to create a new roof structure with a large exhibition space. Two vaulted roof elements now rise over the existing building. They are raised on steel bearers, with glazed strips at the base separating the new from the old structures. Together with a ridge lantern and large areas of glazing to the end faces, these floor-level strips lend the roof an appearance of lightness. Metal louvres at the gable ends and obscured glass fixed beneath the lantern reduce glare and control the direct ingress of daylight.
