It’s a blustery grey day on top of the short-stay car park at Heathrow Central. Down below us the new Terminal 2 building is taking shape in a series of steely whale ribs and arabesques. It doesn’t look like it will turn out to be anything much, but then nothing in the built environment nowadays looks like anything much; or, rather, it all looks like too much – too much airy embellishment, too many wave-form roofs, too many great expanses of curved glass parametrically wrapped around hideous atria. At least Heathrow has this solid virtue: it’s an almost historic airport that has been subjected to over half a century of chopping, changing and concrete-pouring, so that its ugly hugger-mugger of buildings replicates the very disorder of the unplanned metropolis it was never properly designed to serve.
Heathrow is the fons et origo of British spatiality. It was here in 1784 that Captain William Roy measured out a baseline that became the starting point for all subsequent trigonometric surveys of the country. These grew in the years following his death to become the Ordnance Survey. Note the “ordnance” – Roy’s mapping was for military purposes, and really our commonsensical internalised sense of rational, three-dimensional space relates to the ballistics of death-metal.
