The myth of the entire city
Imagine waking up in the morning, walking three blocks to the bakery, stopping by the school where your children study, leaving a coat in the laundry room, meeting your doctor, and still having time to have a coffee before work.
All this without having to drive through endless avenues, which are always congested.
This image, utopian for many, is, in fact, an urban project with a name and surname: The City of 15 Minutes.
And at its base is a fundamental concept that Mapfry now reveals in high definition: Proximity Cores.
Because, mind you, the city is not a single entity, it is made of Fragments that work like cities within the city.
Microcosm of coexistence where life is right there.
The geography of human reach
At first, the concept may sound technical: intra-municipal sections, areas with a high density of services, commerce, housing and mobility.
But what it actually describes is something simpler: the space where everyday life is possible to move with agility.
Each Proximity Core is a portrait of what we call the “human scale”.
From concept to purpose
- Imagining the city based on human needs, Not the road infrastructure
- Rethink the time spent traveling, prioritizing socializing, rest, quality of life
- Allow the place where you live to be a complete place again: Live, work, care, find
There is a change in perspective, which has already begun, and our maps now describe them.
Time is territory
The idea, popularized by urban planners such as Carlos Moreno, but detailed in the essays of Duany and Steuteville in 2021, it starts from a powerful premise: what defines the city is not the space it occupies, but The time it takes to experience it.
Three spheres of reach (or “sheds”)
What urban planners call “sheds”, Mapfry translates into real, visible and quantifiable territories: the Proximity Cores.
These cores are not idealizations, they are urban clippings that emerge from the data.
Through spatial analysis, they reveal The everyday city And where it might turn out to be
Instead of a centrifugal model, with everything gravitating around a center, we now have a Constellation of Nuclei of Local Life.
5 minutes
The neighborhood's epicenter. Here live the hot bread, the usual pharmacy, the neighbor who waves from the balcony.
A “quarter mile” that is, in practice, a ecosystem of trust and routine.
15 minutes
Expanded area: schools, health centers, supermarket.
That's where the weekly tasks are solved. A three-quarters mile radius, or a life resolved in one morning.
+15 minutes
The outer edge of human autonomy. Hospitals, universities, green areas, the bridge between the neighborhood and the larger world.
These three levels organize the city as a living organism with multiple centers.
Why does that matter?
because The human scale is the most efficient
Well-served neighborhoods reduce travel costs imposed on consumers
Profound benefits
- Equity: The centers return the time taken by the city
- Sustainability: Fewer cars = less carbon, more air, more time
- Local economy: corner markets instead of distant hypermarkets
- Social cohesion: more encounters and true connections
The City of 15 Minutes is a choice by city Slower, closer, more human.
