Unadulterated natural materials such as pine clad walls, slate and sisal flooring set the backdrop for the exhibitions. Pine is used in the ceilings, and in the passages between the exhibition rooms daylight is filtered through a suspended ceiling grid of pine slats. The architects' priorities are clearly functional: the materials are simple, solid and unobtrusive not detracting from the exhibits. Integrated into the building are also artworks by Ivar Jåks such as the frieze over the door, the large concrete relief "Dance of the gods" in the lobby and the iconic brass door handle. These as well as Jåks' exhibition designs in collaboration with the duojar (Sámi handicraft maker) Jon Ole Andersen from the early 1980s add to the modernist building's particular Sámi identity.
