Stuttgart. New Castle. From http://www.smart-travel-germany.com/stuttgart-new-castle.html
72 Hour Urban Action is the world's first real-time architecture competition, where 10 international teams have 3 days and 3 nights to design and build projects in public space in response to local needs. 72 Hour Urban Action is working together with local partner, Kunstverein Wagenhallen after a major public protest around the development and re-purposing of the Stuttgart 21 area. The Post 21 program suggests a series of events in response to the local planning crisis and the ongoing public outcry that were the result of the Stuttgart 21 plan. Through it we seek alternative approaches to city planning and different tactics for engaging residents in place-making.
