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.​

The teams design, build, sleep and party on site to generate interventions in public space within an extreme deadline, a tight budget and limited space. 72 Hour Urban Action invites professionals and residents to become active agents of change, from the bottom-up, and to leave a lasting impact on the urban landscape.
