The architects Franz&Sue developed a new spatial concept that combines the refurbished existing buildings to the north and south with a new, connecting component. The external appearance of the secondary school is characterised by a filigree wooden slatted façade. Inside, an open auditorium forms the centrepiece, complemented by bright and inviting areas. A graphic guidance system provides orientation, and generous open spaces offer a variety of opportunities for learning and relaxing.
