The work Alexanderplatz is a second 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.

In contrast to the commonly accepted approach used by designers and architects, these labyrinthine passages were measured using my own subjective measuring system. With finger lengths and counting footsteps, I walked these networks and gauged their internal dimensions and volumes. Technically inexact, this reconstruction can be characterized as a layman�s raw understanding of the spaces that contain the quotidian commuter.

Hallesches Tor is a model-like replica of a Berlin pedestrian underground tunnel linking platforms of the subway network. Here space is excavated: the complex carved-out corridors of the pedestrian tunnel become the �positive� of hidden space. The tunnel, and its human traffic, is transformed into a sculptural object. Attached to both ends of the tunnel are working reproductions of the digital countdown clocks that announce arriving and departing trains. From small speakers placed inside the tunnel the continuous music of the street musicians who play there, as well as the rushing footsteps of commuters, can be heard.
