You have just about a week to put a team together and vie for one of the spots in the next edition of the 72 Hour Urban Action competition, which the organizers bill as “the world’s first real-time architecture competition.” If you can find only a couple of interested colleagues or no one at all, you can still apply as an individual participant or a small team, and if selected, you will then be joined into a larger team.

There will be ten teams in all. On take-off day on July 11, 2012, those teams will be tasked to “realize projects in response to the spatial and social challenges the sites and missions offer.” That is, in just 72 hours, they will actually have to build something that will “leave a lasting impact on the city’s urban fabric.” And for all their efforts, the winning team will receive $4,000.

The members of the jury is worth mentioning. They include Joseph Grima, the editor-in-chief of Domus, and Eva Franch i Gilabert, director of Storefront for Art and Architecture. Also a member is Benjamin Foerster Bladenius of Raumlabor, the urban collective who designed a bubble pavilion, called the Spacebuster, which can be inflated almost anywhere and anytime into “a billowing urban room.”
