'We're afraid of walkable distances now?' — conspiracies and the '15-minute city'

The polite world of urban planning has become the latest target of conspiracy theorists. In recent weeks, the 15-minute city concept — where neighbourhoods provide life's essentials in 15 minutes by foot or bike — has become a harbinger of big brother in conspiracy-land. Brent Toderian, a keen urbanist and Vancouver's former chief planner, is here to help us understand how a "mundane" urban planning concept has prompted protests in Canada and the UK.  Later, we turn to the disaster zone in southern Turkiyë and northern Syria to understand what shelter is available — and appropriate — for those displaced. Tom Bamforth, a writer and aid worker who who specialises in shelter and settlements, joins Blueprint to canvas what kinds of shelters are available — from Ikea's award-winning flatpack to the DIY . And Blueprint regulars Annie Smithers and Colin Bisset return with some sweets and stories: Annie with the inside scoop on strawberry sorbets, and Colin with the pioneering African American woman who changed architectural history.
