What the Blue Zones taught us about building a walkable community at Tilisi

Every day at work, I see the same thing. Clusters of children (on their bikes, on the sports court, in the swimming pool) playing and bonding with each other. Nobody organized it. Nobody booked a slot. They just found each other.

I didn’t think much of it at first. Then I started reading about the Blue Zones, and it changed how I think about building a master-planned community in Kenya

What are the Blue Zones?

You’ve probably heard of them: a handful of places, including highland Sardinia, Okinawa and Costa Rica’s Nicoya Peninsula, where unusual numbers of people live into their nineties and beyond.

The honest truth is that some of the records behind them are shaky. In 2024, a UCL demographer won an Ig Nobel prize for showing that many extreme-age claims trace back to bad paperwork.

But once you strip out the hype, two Blue Zone habits hold up remarkably well:

• Moving naturally through the day.

• Being woven into other people.

A review of 148 studies covering more than 300,000 people found that strong social ties raise the odds of survival by roughly 50%. That’s an effect comparable with quitting smoking.

Here’s the part that matters to us: neither habit runs on willpower. Both are shaped by the places we build. Which is exactly what those children were showing me.

Why walkable neighborhoods matter in Kenya

This matters more in Kenya than people realize. According to the Kenya National Bureau of Statistics’ 2023/24 housing survey, 72.7% of Kenyans walk to work. Whether those walks are safe or pleasant is debatable, and they’ve probably become less pleasant as the city has grown more congested.

The standard pitch for property is square meters, finishes and yields. Buyers should care about all three. But I’ve come to believe the most important thing we design isn’t inside the unit. It’s the walk between the front door and everything else.

A 2016 Lancet study tracked 6,822 adults across 14 cities. People in the most walkable neighborhoods did 68–89 more active minutes a week than those in the least, without anyone deciding to exercise. Four things made the difference: density, connected streets, access to transport, and parks.

How we’re designing Tilisi for healthy, connected living

1. Move naturally

Tilisi was master planned with footpaths, cycle lanes and a 6.8km jogging track. The aim is simple: the easiest way to get somewhere should also be the healthiest. A sports court you pass on the way home gets used. Movement works best when it’s part of the day, not a separate appointment.

2. Design for collisions

Belonging happens where people pause. Our clubhouses, kids’ play areas, heated pools and sports courts aren’t brochure items. They’re where residents bump into each other every day.

The children worked this out long before I did. Meanwhile, their parents are catching up on the sidelines, which is why seating beside the play area matters more than people think. Parents talk. Friendships start. It’s a big part of what makes this a family-friendly estate near Nairobi, not just another development.

3. Seed the right tribe

Good design gets you halfway. The rest is people. Our in-house property management team organizes quarterly gatherings: small rituals that turn neighbors into a community.

4. Live, work, play

Tilisi’s 400-acre masterplan puts homes, a school, healthcare and workplaces within one secure environment, 25km from Westlands. Less time in traffic means more time for the things, and the people, that keep you well. That’s the real promise of a live, work, play community.

What we will and won’t promise

What we won’t do is promise you extra years. Nobody can back that up honestly.

What we can measure, we will: minutes to transport, kilometers of footpath, how many neighbors you know by name.

There’s evidence this kind of design pays off for whole communities, too. In Albert Lea, a small town in Minnesota, a street redesign built around walking was followed by downtown foot traffic rising 96% and property values climbing 25%, according to the state’s transport department. That’s one US town, not a forecast for Maisha. But it tells you which way the logic runs.

Built for the long run

We built Maisha for the long run. It turns out that isn’t just a line about our business. It’s a design brief for how people should live.

If you’d like to see it for yourself, come and walk Tilisi with us. Come in the late afternoon. You’ll see what I mean.
