This model proves that indigenous materials like terracotta are far more effective than modern concrete for cooling and flood-proofing South Asia’s dense urban centers. It is a powerful blueprint for reclaiming chaotic streets for people while restoring cultural dignity through sustainable design.

Pakistani & Indian Streets Could Look Like This…Added:
Karachi is one of the most chaotic cities I've ever walked through.
But hidden inside this madness is a street designed to show what Pakistan's cities could look like with proper urban planning.
And apparently something incredible happens the moment you enter.
So let's see if it lives up to the hype.
I've read a lot about it online.
It's called the Denso Hall Walking Street.
You'll know we're there because you know the cars will stop, the motorcycles will stop, and there's a few special things about it.
I'll tell you about it as we get there.
It's really hot out here.
It's like 30 degrees.
Denso Hall Walking Street.
Okay, let's let's keep going.
Okay.
Here's the entrance to the street where the motorcycles end.
A bit of parking out here.
And so out there, it's like 28 degrees.
But as soon as I'm getting closer to this walking street, the temperatures drop literally ten degrees.
I'm not kidding you.
And the weird thing is, you can physically feel the difference immediately.
And it's just a lot more peaceful already.
I'll tell you why the temperatures dropped.
So it's because of the ground.
Have a look at the ground here.
See this?
This is terracotta.
It's not asphalt.
It's not pavement stones like out there.
It's terracotta.
And so these tiles, they soak in the water and they release the water as well.
Works like a natural AC.
Thank you.
He saw the camera and thought the BBC had finally arrived.
But honestly… he’s got a point.
So if anyone’s watching, please fix these potholes.
And even got, like, a sign here which says what they're doing.
So yeah, water is absorbed and it goes into this garden here.
So they got less of a flooding issue because these terracotta tiles, they let the water go down into the ground basically.
And yeah, they've also built trees in here.
So that's why the temperature would have dropped.
There's a whole garden in the middle of this terracotta walking street.
Incredible, man.
Hang on a sec.
Is that Gujarati up there?
Long before modern borders existed.
Traders from western India, especially Gujaratis, built communities across port cities like Karachi.
And even today, traces of that history still survive above old homes and shopfronts.
And I found this across Sindh and you will see it when I get out of Karachi.
And I go into Interior Sind as well.
This is what we need all across Karachi.
And so apparently these terracotta tiles, they were built by women who used the beg here.
They gave those women jobs to build the tiles, all the tiles for this street, and it's quite long so they wouldn't need a lot.
But the deeper we walked, the more I realized this wasn't just a tourist street.
I think the power’s gone off.
That's why you can hear like a generator over here.
People are selling all sorts of stuff, man.
There's like tools, locks.
Markets all the way down these gullies.
There's a toy store.
This is like, oh, people are having having food out here as well.
So I think they're eating chicken korma.
Yeah.
It’s definitely chicken korma and bread.
This is the bread making station.
They’re putting the naan (bread) into the tandoor there and they'll pull it out and serve it.
So yeah just an outdoor dining area here.
And everybody's enjoying, enjoying lunch.
Basically a food court in the middle of the trees.
What are they selling?
Hi.
Oh, so they're having like chickpeas and bread.
Looks good. Looks nice.
Because there are no vehicles here.
People actually sit outside, eat together and spend time here.
There's no dust.
There's no fumes.
It's lovely.
Like just tons of gullies.
Look at this cat.
Look at this Look at this cat down here.
This cat is just.
Just hanging out.
This guy is bargaining for... These are fake Skechers.
Skechers shoes.
Ok.
So... of fake Skechers here.
Pretty good.
And you can buy clothes.
Yeah.
Here's the generator.
I was talking about making all the noise.
The power goes off quite a lot here in Karachi.
It's actually a joy to walk down.
I wish all of Karachi was like this.
It should be, na?
They've got an entire clothing market in the centre here.
And if you look up, you will see some very old buildings.
Very old buildings.
Let's see how much further this goes.
I think they're trying to build this walking street throughout the city.
They're trying to continue it.
But I'm sure nothing is easy here.
Yeah, it ends here.
You see, the whole street is bloody blocked here.
This is a normal market.
It’s all blocked, man.
Look at that down there.
Crazy.
And then kind of back to the madness, you know?
Of cars and bikes everywhere.
Rickshaws trying to get through people.
See, this is the difference, na?
this is what normal old Pakistan is like.
Just a bit of a mess.
Let me know in the comments.
Should they build these walking streets throughout Pakistan?
