Mathias Pöschl proposes an architectural intervention using simple measures, with a special focus on the glass surfaces in the entrance hall and on the long wall in the schoolyard. His design involves painting a black ribbon using insulating bitumen paint. The ribbon along the schoolyard wall is intended to highlight this boundary; the application inside creates a visual separator, where the black surfaces appear matt in the entrance hall, but reflective in the music room and library. This type of painted surface is a reference to school blackboards, and the surfaces can also be used and adorned by the students themselves. Because this intervention is so simple in its realisation, the remaining project budget will be divided up between the school’s music department and the library, for the purchase of books, instruments and supplies.
