London Ends Where a Committee Decided It Would — Epoche B1
Drive north-west out of London and the houses stop, suddenly, at fields. That edge is not natural. It is the Metropolitan Green Belt, a ring of land around the city where building has been heavily restricted since the 1950s, when national policy invited councils across England to draw such rings around their towns. The case for it is strong. Other capitals spread outwards until the countryside was an hour away by car; London did not. Green belt now covers something like an eighth of England's land, and it means that millions of people can reach open fields by bus. It also protected farmland from a kind of building that would have been irreversible. Once a meadow is a car park, it is a car park for good. The case against is equally concrete. England has too few homes and they cost too much, and the belt holds back land beside stations where houses would make obvious sense. Workers priced out do not stay inside the ring; they buy beyond it and commute across it, so the belt lengthened journeys rather than shortening them. And much of the protected land is not meadow at all. Golf courses, scrubland and the odd depot enjoy the same defence as ancient woodland, simply because of where the line was drawn. The two arguments only meet when we ask what the belt is for. If the answer is openness itself, defend every acre. If it is beauty, farming and access, then a scrappy field beside a railway station is protected by the map alone. National planning policy has lately begun to separate out such lower-quality land. That is progress, and it concedes the point: the edge of a city is a decision, and decisions can be revisited. References Ministry of Housing and Local Government (1955). Circular 42/55: Green Belts.
