The concept developed by Adrien Tirtiaux and Ursula Gaisbauer is inspired by the architectural design, which connects the different structures and their different historical backgrounds on one continuous level. The title, Niveau anheben (Raising the Level), alludes to the architectural level, but can also be interpreted in the context of school and education. The intervention runs through the entire building: a line drawn on the exterior facade marks the defined ±0 level of the historical building. The second intervention is a continuous, light-green ribbon across the ground-floor windows. This serves as a visual separator and creates a bright and airy atmosphere inside. The last element of this three-part intervention uses the wall in the schoolyard, which is coated with shiny, bright yellow paint. This is a clearly abstract signal that is also reminiscent of the body of a bubble level.
