From suburban semis with picket fences to mansions with their moats, the British have always used architecture to express their love of a good boundary: the rich man in his castle, the poor man at the gate. Look around London and everywhere you will see the architectural signals that define people past and present, their place in society, and the distribution of property.

Perhaps Brexit is a logical extension of that British desire to retreat within a national boundary – to find an imagined comfort zone and put the rest of the world in its place. But architecture in Britain – and London in particular – isn’t always so insular. London’s architects have long stepped outside national boundaries to build around the world – all the while pushing the boundaries of what a building should look like and what modern engineering can do.

London developed as a city of villages. But who really knows where Hoxton ends and Shoreditch begins? Perhaps boundaries are made to be blurred? In a city where postcode or social boundaries can be deadly, architecture should be used to shape a city that is safer and more at ease with its diversity.
