72 Hour Urban Action is the world’s first real-time architecture competition. It has an extreme deadline, a tight budget, and limited space to respond to, and resolve, local community needs. Teams have three days and three nights to plan and realise projects in response to assigned missions, developed together with the local community. The aim is to transform the public realm and to raise ambitions amongst residents and the municipality for higher quality public space, while demonstrating that this need not be costly, nor take a very long time.
