The cycle “Theatrum Orbis Terrarum” is designed as a long-term project. Its title alludes to the first modern atlas published by Abraham Ortelius. Classical media of architectural representation – plans, perspectives and models – are used to explore planned and built spaces from different geographical regions and historical periods. This is done in a process that is at once analytical-critical and speculative. Spatial situations – and the social, political, and cultural contexts in which they are embedded – are examined and simultaneously manipulated and alienated through operations of scaling, repetition, mirroring, and exaggeration. Particular attention is paid to the moment when functional planning and utopias turn into their opposite – when efficiency efforts and grand scales lead to inhuman situations – and when seemingly neutral structures reveal their ideological foundations. Palaces, monuments, cathedrals, prisons, camps, fortresses, bunkers, slaughterhouses, shopping malls, housing complexes, infrastructural buildings etc. are thus condensed into an architectural phantasmagoria that is situated between fiction and reality.
