20.000 Blocks

The DDU collaborates with the Internationale Bauausstellung (IBA) Heidelberg in designing an urban vision for the Patrick Henry Village (PHV) near the historical city of Heidelberg. The 100-hectare area, used until 2013 by the US army, is to become a model for how future cities can house our knowledge-based society.

IBAs – the International Building Exhibitions in Germany – are one of the most influential and innovative urban development instruments in Germany, going back to the beginning of the 20th century. We are very excited to be part of the upcoming IBA Heidelberg, focussing on „knowledge based urbanism“.

Our team at the Digital Design Unit (DDU) develops a custom version of the game platform 20.000 Blocks — the IBA_GAME | 20.000 BLOCKS — with the aim to involve the youngest citizens in envisioning the new PHV. Together with case studies conducted by the world-renowned offices of MVRDV, Carlo Ratti Associatti, ASTOC, Ramboll Liveable Cities Lab and Bohn&Viljoen our contribution will inspire the urban vision by KCAP for the area of this new neighbourhood of Heidelberg.

The game IBA_GAME | 20.000 BLOCKS is made possible by the kind support of Eternit.
