Megastructural town center
Radical modernist new-town experiment
Cumbernauld, designated in 1955 and planned by the Cumbernauld Development Corporation, was a Scottish new town intended to relieve overcrowded Glasgow. Breaking with the neighbourhood-unit model of earlier British new towns, it concentrated the whole population around a single dense hilltop core, crowned by a multi-level megastructural town centre that stacked shopping, civic functions, parking and penthouse housing in one linear building. The plan separated pedestrians and vehicles completely, with footpath networks threading through housing areas towards the centre.
Cumbernauld became the emblematic 'Mark II' new town, studied worldwide as the most radical modernist experiment of the British new-towns programme. Its town centre was celebrated in the 1960s as a built megastructure and later became a byword for the difficulties of that idea, fuelling debates about monumental concrete urbanism and its maintenance. It remains a key reference point in histories of welfare-state planning and megastructural design.
