Qianhai – or, to give it its formal title, the “Qianhai Shenzhen-Hong Kong Modern Service Industry Cooperation Zone” – is the very model of a modern urban centre.
On paper, it looks like something out of Star Wars: an arc of skyscrapers rising from reclaimed coastal lands and standing sentinel round a circular harbour. Wide boulevards and geometric patterns proclaim a sense of order and good governance: a safe place for the world’s capital.

“It’s a hot topic of debate whether Qianhai will be in competition with Hong Kong,” says Marcos Chan, head of research for Hong Kong, Macau and Taiwan for real-estate multinational CBRE. “Here we have a big piece of land in Shenzhen with potentially up to some 150 million square feet of office space that effectively transforms it into a new strategic centre for commerce, finance and the professional services.
