There are areas we've all watched transform almost without noticing.
We come back after a few years and find more buildings, restaurants, retail, offices and people. Land is worth more, new investment appears, and that place ends up becoming one of those spots where many people want to live, work, shop or open a business.
When I walk through areas that have gone through that process, I'm no longer surprised just by everything new that arrived. Lately I've been trying to observe something different:
How much further can a place keep growing before that very growth starts taking away part of what made it attractive?
Because everything has a limit.
We can build more housing on the same plot, shrink units to keep the purchase price down, add more retail, and receive more people, suppliers, delivery riders and vehicles.
But there are things that are much harder to expand:
- A street.
- A sidewalk.
- A park.
- The capacity of certain networks.
- The time we need to get around.
- The space needed for all those activities to coexist.
And that's where the issue stops being purely urban.
- In housing, if we keep shrinking apartments, what happens outside them starts to matter much more. A plaza, a park, a café, a good sidewalk, or simply a place to stay stop being extras and start becoming part of the experience of living there.
- Something similar happens in retail. Having more and more population nearby isn't enough. Customers need to be able to arrive, walk, stay and enjoy the surroundings. We can have a huge market and, at the same time, be turning the area into a place that's increasingly hard to visit.
- And in logistics, the limit becomes even more visible. As housing, restaurants and stores grow, so does everything that needs to come in and out: goods, food, parcels, returns, suppliers and waste.
If we never leave room for that operation, we know what ends up happening:
Logistics finds its space on the street and on the sidewalk.
Not because that's the model anyone designed, but because growth arrived before the solution did.
And maybe that's one of the first signals we should learn to recognize.
As an area grows, we all make small adjustments. We leave earlier, accept taking longer, suppliers change their schedules, apartments lose square meters, and businesses make use of every available space.
Until a moment arrives when the place keeps growing, but using it starts costing us more.
That cost doesn't necessarily show up right away in the price per square meter either.
An area can keep appreciating. Projects can keep selling and restaurants can stay full while the everyday experience starts to deteriorate.
That's why price, on its own, can warn us too late.
And some cities have already had to face that contradiction.
- Barcelona began recovering, through its superblocks, part of the space certain streets had given over to cars. What's interesting isn't just that there are fewer vehicles in certain areas, but what changes for those who live or spend time there: more places appear to walk, meet, or simply stay.
- Paris is doing something different around hundreds of schools. Streets once dominated by cars are gaining pedestrian space and greenery. Seen from the point of view of someone living in the city, the change is very concrete: a child who can walk more safely, a family that can stop, a neighbor who gets back part of their street.
- Seoul caught my attention with an even simpler idea: thinking about even the shaded route between home and everyday places like transit, the market, school or the park. It's no longer just about how many trees there are, but about how a person experiences that route.
Three very different cities and three different solutions.
But behind them I find the same question:
How will people keep living in an area once a lot more people arrive?
And I think that question is just as useful for those of us making decisions in housing, retail, logistics, development or investment.
That's why, when I analyze a growing area today, I try to look at four things:
- What are we starting to compress in order to keep growing? The size of homes, public space, parking, loading and unloading areas, or even our own time.
- What activity is starting to use spaces that were never designed for it? A sidewalk used for deliveries or a street permanently turned into parking can be telling us, long before some statistics do, that something is starting to be missing.
- Are we really improving the place, or just increasing its intensity? More population, more buildings or more retail don't necessarily mean a better experience.
- What would need to change today for that area to still be attractive ten years from now?
For me, this last question is the most important one.
Because it's not about stopping growth.
It's about making sure whatever sustains that growth grows too.
- More housing needs mobility, services and better outdoor space.
- More retail needs accessibility and capacity to receive customers and suppliers.
- More density needs better public space.
- More activity needs logistics planned in advance, not solved later on streets and sidewalks.
And maybe that's also where an opportunity lies that we often overlook.
When an area reaches a certain intensity, what starts to be missing can become the market's next need.
- It could be a new service.
- A different retail format.
- A logistics solution.
- Another form of mobility.
- More space to stay.
Or even another area capable of offering what this one started to lose.
Over the years I've learned that a location can still have a lot of growth potential and, at the same time, very little capacity to keep growing the same way.
That, for me, is the point we shouldn't lose sight of:
The real risk may not be that an area stops growing, but that it keeps growing after it has already started losing what made it valuable.
That's why, when I look at an area full of activity and new projects today, besides asking how much more it can grow, I try to understand something different:
What are we starting to sacrifice so it can keep growing?
Because maybe the limit doesn't appear when we can no longer build another building.
It can appear much earlier, when those who live, work, shop, supply or visit that place start to feel there's a better alternative.
Where do you think that limit begins?
