The 2013 Bi-City Biennale of Urbanism\Architecture in Shenzhen took ‘urban border’ as its theme. For good reason. If there is a place to study ‘border’ as condition, it is Shenzhen.Demographic, territorial, economic, political, social, and legal borders created this fifteen million city in less than thirty-five years, and drive its further development.
‘It’s legal, but is it legitimate?’ and ‘It’s legitimate, but is it legal?’ These are questions rarely discussed in public concerning architecture and urban design. Yet architects have to deal with rules and regulations, and architecture is to a large extent defined by them.
