Three temporary sites in East London are up for grabs in a new Site Life competition

London mayor Boris Johnson and mayor of Newham Sir Robin Wales have joined forces with Building and its sister publication Property Week to find “meanwhile” uses for three key sites in London’s Royal Docks and Canning Town.

The new SiteLife competition follows a similar competition in Manchester , which sought to find “meanwhile” uses for an Urban Splash development site.

The Meanwhile London competition is an opportunity for people including developers, investors, designers, artists, community groups and entrepeuners, to devise temporary uses for three prominent sites for at least a year from Summer 2011.

The sites will be in the spotlight in the run up to the 2012 Olympics, as they all lie on or close to the route between the main Olympic site at Stratford and the ExCel centre, which will host several events.
