Together with MVRDV we developed the concept and design of an urban installation for the Architectural Biennale in Bordeaux of a plan of MVRDV for Bastide Niel in Bordeaux, France. The installation is placed in the working "water and cloud fountain”: the Miroir d’eau. Every half an hour there is building up a cloud over the square. People are invited to walk in the model and look through the new streets and see the shapes of the new neighbourhood. The roofscape with its characteristic spires can be observed in an overview from elevated tennis referee chairs. We collaborated with furniture maker Gert Jan Bok on the realisation of the project.
