The 15-Minute City Is an Old Idea Wearing a New Name

The "15-minute city" is usually presented as a novel planning concept, but nearly every city built before mass car ownership was, functionally, already organized this way — daily needs within a short walk, because that was the only practical option available. What's actually new isn't the idea; it's the deliberate attempt to reintroduce it into cities that spent decades being redesigned around car travel instead.

That redesign wasn't neutral. Zoning that separates housing from commerce and workplaces, and infrastructure built to prioritize vehicle throughput over walkability, didn't happen by accident — it reflected a specific set of planning assumptions about cars that dominated for most of the twentieth century, and reversing it requires undoing decades of built infrastructure, not just writing a new plan.

The debate over 15-minute cities is really a debate over whose convenience urban design should optimize for: drivers moving through a neighborhood, or residents living inside one. Framed that way, it's less a radical new philosophy and more a return to a much older default that the automotive era temporarily displaced.
