The concept for the distinctive design of the Olympic Hall (the "Viking Ship") in Hamar was already in place when we discovered that the roof itself, which is naturally the most challenging element when it comes to such huge structures, could be given the necessary lightness and flexibility if we freed it completely from the static and somewhat unattractive shape of the arena.

We brought in daylight to describe the play of lines along the length of the roof against the horizontal beams. On the outside, luminous slits make the roof appear lighter.

The enormous size of the hall and its striking design made it desirable to tone down the effect of materials and colours.
