The Urbantine Project is a Tent London initiative being run in conjunction with London-based property firm Workspace Group.
The designer behind the winning entry will receive £10,000 to build its 'tent' which will then be showcased at the Truman Brewery in east London's Brick Lane as part of September's Tent London 2007 exhibition.
The tent will also be displayed as part of the London Architecture Biennale in 2008, and its creator given the chance to work with the Workspace Group.
Tent London is run by Ian Rudge - the co founder of 100 per cent Design. Rudge said: 'If you are a young emerging architect or practice you want your buildings built. The idea of this compettion is so they can just do it.'
'It is about fast architecture,' he added.
Entries for the Urbantine Project must be in by 16 July. For more information and an application form, click here.
