In the early baroque building in Vienna’s city centre, the “Domus Universitatis” – part of Vienna’s first university – the existing inner courtyard could be enriched with an escape staircase – as an interesting new architectural element.

The listed building requires a careful and conscious approach to the existing architecture. Thus, instead of minimising space, a new experienceable space could be added to the very small courtyard with an escape staircase as a walk-in sculpture.

The steel pillars, which tilt towards each other, appear like three rods placed in space; they form the supporting core of the newly constructed escape staircase.
