The Norwegian architecture firm has expanded upon the neo-classical design of the original building. Designed as a three-winged mansion during the First World War, the museum extension was finished in 2005 and expanded by 1,150 sq m.
The extension, dubbed Himmelhaven, uses glass and black lava concrete. The surrounding landscape was partially excavated and allows a continuous path through the exhibits. This ensures a clear and intuitive path through the museum and allows accessibility for all visitors.
In addition, five new underground spaces serve for exhibitions including three dedicated to the museum’s extension collective of French impressionist paintings.
The largest of these exhibition spaces utilises a steel-coated structure that is cut in a way that allows light to reflect in many directions. This allows the light to change dramatically throughout the different seasons and weather conditions.
In contrast to the reflective steel, the inside of the exhibition spaces is entirely dedicated to softness and comfort. Velvet lining alludes to the feeling of a classic jewellery box and indicates that you are within a precious location.
Within a mini-atrium, visitors can sit down and enjoy the vibrant colours of the park surrounding the museum. Fruit-bearing trees adorn the landscape as an emulation of English parks.
