“The Playful City
The London Festival of Architecture is a city-wide celebration of architecture and architectural talent in the UK capital. It brings architects and communities together to examine how we make London a better place. The theme of the 2012 Festival – ‘The Playful City’ – responds to the presence in London of the Olympic and Paralympic Games.” (http://www.lfa2012.org/)
