What makes a model a model? Milica Topalovic investigates the characteristic qualities of the model. The difference between models and buildings seems obvious. A model is made on the scale necessary to get something (an idea) across, while a building is by definition the 1:1 reality of the architectural idea. There are, however, spaces that escape this distinction and for which the scale is not the distinguishing factor, such as the 1:1 installations of artists Gregor Schneider, Hans Schabus and Guillaume Bijl: ‘they seem to linger on the edge of reality: they might look too simple or too perfect or even too familiar’.
