On the basis of a pitch written on an iPhone on the top of a mountain in Ethiopia, I was invited to curate the UK Pavilion at the 2013 Shenzhen Biennale of Architecture and Urbanism. The eventual pavilion was curated, designed and produced by students and staff from Central Saint Martins, and took the theme of Liquid Boundaries - arguing the need to find ways through the hardening of space as it is being increasingly controlled, regulated and divided. The pavilion presented four films, each 129 seconds long (the average time someone spends in a national pavilion at the Venice Biennale), which interpreted briefs provided by four UK architects and spatial agents. All in their own way open up ways in which boundaries might be negotiated with, and in so doing a more democratic form of space emerges. More information, including a downloadable pamphlet and 'user manual', can be found on the Liquid Boundaries website.
