The 'Zuidas' continues to be a challenge as a major urban development area. The fourth edition of Zuidas Free Spaces AIR once again presents art as an inspiration for reflection and projection. The project offers insight into the ideas and ambitions steering the design of this area, responds to and comments upon them. This provides further insight into the consequences of policy and planning. It poses and presents independent questions, insights, conclusions and viewpoints, things of value to the thinking and policy on the Zuidas as a developing area and as a new city district of Amsterdam.
