The modernization and expansion of the building of the State Secondary Music School in Katowice necessitated the creation of a system supporting orientation in the building's space. An important aspect of the project was maintaining the consistent nature of all system elements - typeface, pictograms, method of communication, naming of functions, as well as the type of media used. An clear, minimalist and modern system was designed. An original set of linear pictograms makes it easier for young school users to use its zones and functions, perfectly matching the school's interior.
