The functionality of the old fire station facilities was no longer adequate to meet today's needs, and the main goal was to adjust the space to the Clean Fire Station concept, meaning that all exposure to flue gases and smoke will be left in the washroom immediately and will not spread around the station. The design of the new Äänekoski fire station started off as a refurbishment project, but became more of a new project due to completely new idea of building. Evolution panels have been used in the facade cladding enabling more flexibility at the design stage.
