The interior design of the building is a tribute to the principle of the Gesamtkunstwerk, that is, the total work of art. The design of each lamp, piece of furniture, panel, flooring material and decorative board is a reflection of Aalto's maturity resulting from his long career as an architect as well as designer of lamps, furniture and fixtures such as door handles. All the materials speak the language of nature, without technically artificial tones. This is because Aalto's basic view was that architecture should create a frame for human beings. In the Finlandia Hall, the focus is not on extraordinary forms or ostentatious interior, but rather on the audience and on the performers. According to Aalto, the audience at the Finlandia Hall need not dress up like people used to in the opera house foyers and gilded concert halls of the old days. What people wear should be as genuine and natural as the environment in the building.
