The extension was therefore implemented with great respect for the existing architecture. From outside, the extension continues the existing facade’s rhythm and proportions, and retains Arken’s distinctive expression. From within, however, the extension is characterised by great simplicity. The new exhibition halls have been given very clean lines and are laid out as four large, white rooms in dynamic contact with each other. There are no load-bearing walls or columns in the individual rooms, the air conditioning is recessed into the walls, and the security equipment is located in floor boxes beneath simple steel plates. An additional extension offers facilities for visiting groups of school pupils with workshops etc.
