Shrinking city Silberhöhe

Interactive real-time visualisation

The city Halle/Saale is shrinking! It’s shrinking that much, that you could tear down a whole part of  the city because all these flats are not needed any more. The idea is to remove the concrete and let nature reclaim the area. It’s an extreme scenario and it got shown at the exhibition “Wandelhalle” to create awareness and discussion.


In an interactive real-time 3D visualisation the visitor can travel into the future and see how the area will ‘develop’. The application is divided in two layers. The first layer is a more abstract view from outside where it’s possible to move smoothly through time. The second layer shows realistic views how important areas are planned to being changed.

Shown at the exhibition “Wandelhalle – Stadt als Ansichtssache”
