Challenger Cities EP37: The Recipe Book for Cities with Guillermo Bernal

The City’s Recipe Book: Borrow the Technique, Use Your Own Ingredients with Guillermo Bernal

Cities don’t work because of glossy plans or polished renderings. They work because people use them, reshape them, and often subvert them in ways no planner predicted.

That’s the world Guillermo Bernal inhabits. A political scientist turned place-maker, Guillermo has spent the past decade helping communities across Mexico reclaim their public spaces — not through sweeping vision statements, but through small, tangible acts of change.

In this episode, we explore:

• Why cookbook urbanism (copying the look of other cities) fails without understanding the “ingredients” that make it work
• How Mexico City thrives on improvisation, adaptation, and citizen-led transformation
• The risks of chasing authenticity until it becomes a product — and what happens when places lose their soul
• Why trusting citizens with public spaces leads to more vibrant, cared-for cities

Guillermo reminds us that the best cities aren’t perfect or polished. They’re unfinished, alive, and constantly rewriting their own rules.
