Fast grid roads, roundabouts, linear parks
Flexible car-era new town at metropolitan scale
Milton Keynes, designated in 1967 as the largest of Britain's new towns, was planned by the Milton Keynes Development Corporation with consultants Llewelyn-Davies, Weeks, Forestier-Walker and Bor. The plan rejected both the neighbourhood unit and the megastructure in favour of a lattice of fast grid roads defining roughly kilometre-square environmental areas, with linear parks along the valleys, a low-density dispersed form and a deliberately flexible, non-hierarchical structure open to change.
Milton Keynes represents the late, self-critical phase of the British new-towns programme, absorbing Californian ideas about mobility, choice and indeterminacy into a state-built city. Its grid and forest-city landscape have been read both as a successful accommodation of the car age and as an emblem of auto-dependent dispersal, keeping it at the centre of debates about density, flexibility and the legacy of welfare-state urbanism.
Realised as Britain's largest and most successful new town, it has grown to roughly its planned size and continues to expand.
Its car-oriented grid produced low densities and weak public-transport viability, leaving it heavily dependent on the private car.
