U-TURN Quadrennial for Contemporary Art has invited the three Danish architect studios BIG, EFFEKT and POLYFORM to battle in new and exciting city planning ideas for the city of Copenhagen. The battle is with LEGO bricks and is an event arranged in relation to Olafur Eliasson's interactive artwork The collectivity project at Rådhuspladsen - an urban planning experiment that encourages everyone to join in the construction of a micro-Copenhagen.

The event takes place on Friday October 17 from 12-4pm at Rådhuspladsen

The collectivity project by Olafur Eliasson is exhibited at Rådhuspladsen (The City Hall Square) in Copenhagen from 11 - 19 October 2008.
