The Industrial Revolution caused a paradigm shift from an agrarian economy to a manufacturing economy, giving birth to the industrial city. ‘City’ became synonymous with a concentration of factories causing unfiltered scenes between centres of production and urban dwellings. The corrupted image of the city ultimately led to the displacement and separation of production away from residential zones in the 20th century. However, new innovative manufacturing technologies are allowing a coexistence between factories and dwellings through hybrid typologies that blend production back into the urban fabric. This AD issue discusses the implications of the re-emergence of production as an architectural and urban agenda through hybrid models that engage a new socioeconomic shift. Given the contemporary circumstances of a global pandemic affecting global supply chains, it is necessary to deliver a vision for a new productive urbanism that allows autonomous circular economies to flourish. Our 21st-century cities have an obligation to explore a new industrial revolution of shared economies that optimise the use of the legacy systems, infrastructure and building stock. Yet it is ultimately up to architecture to take arms in delivering new typologies.
