A megastructural frame of craneways into which obsolescent capsules plug and are replaced.
The defining image of the consumerist, change-driven megastructure utopia.
Plug-in City is an unbuilt project of 1964 by Peter Cook of the Archigram group, conceived as a 'maximum pressure area' to be superimposed on a city and capable of extension across the landscape. It proposes a permanent diagonal megastructure of structural tubes and craneways within which standardised capsules — dwellings, shops, offices and services — are slotted in. Each element is assigned a deliberately limited lifespan, and the integral cranes continually remove and replace components as they become obsolete. There is no fixed final form: the city is an armature for perpetual renewal, expressed through bright, comic-strip drawings that emphasise interchangeable, mass-produced parts.
Plug-in City crystallised the 1960s megastructure idea that a city could be a serviced frame accommodating constant, consumer-paced change rather than a stable composition. Its imagery of capsules, craneways and planned obsolescence influenced a generation of architects, the Metabolists and later high-tech architecture. Though never built, it remains a reference point for debates about flexibility, indeterminacy and technology in urban form.
Purely speculative and never built, it nonetheless became one of the most influential images of 1960s avant-garde urbanism and high-tech architecture.
The vision of perpetual obsolescence and crane-driven renewal ignored the cost, permanence and social attachment of real urban fabric.
