 The work Alexanderplatz is a model-like replica of a pedestrian underground system. It makes visible the various abstract spaces we don’t see, those that leave virtually no mark on the city’s surface. Here, space is excavated: the complex carved-out corridors of the pedestrian tunnels become the ‘positive’ of hidden space. The miniaturized scale and reconstruction of this space is based on a subjective measuring system. Using my body's lengths and counting footsteps, I walked this network myself and gauged the internal dimensions and volumes of its platforms, halls, passageways, stairwells and elevator shafts. Technically inexact, this reconstruction can be characterized as a layman’s raw understanding of the spaces that contain the quotidian commuter.
