Why Mukesh Ambani and Nita Ambani’s Rs 15,000 crore Antilia has NO outdoor AC units — And why the family lives on the 27th Floor

If you have ever driven down Altamount Road and felt your eyes instinctively lift, you already understand Antilia’s peculiar gravity. Mumbai is not a city that pauses easily, yet this one structure makes traffic slow and conversations trail off. Rising roughly 568 feet above one of the world’s most expensive residential stretches, Antilia is less a house and more a vertical statement — a Rs 15,000 crore (approximately USD 1.8 billion) declaration that wealth, when combined with conviction, can quite literally reshape a skyline. Owned by Mukesh Ambani and Nita Ambani, Antilia is among the most expensive private homes on the planet. Yet behind the helipads, hanging gardens and whispered numbers lies a far more intriguing story — one not about excess, but about air, light, and the quiet logic of how a family chooses to live when it can afford absolutely anything.

Before we reach the now-famous 27th floor — the Ambanis’ private sky residence — we need to address the rumour that refuses to die: that Antilia has no air-conditioning.

The AC Myth That Refused To Cool Down — And What’s Actually True

For years, social media has confidently claimed that Antilia has no ACs. The idea travelled fast because it sounded deliciously absurd. Mumbai without air-conditioning? In a billionaire’s home? Impossible.

The truth, however, is far more interesting.

Antilia does not have visible outdoor AC units. There are no metal compressors jutting out to disrupt the building’s carefully balanced façade of glass, stone and steel. Instead, the residence uses an advanced centralised climate-control system, designed less for human comfort and more for architectural preservation.

The temperature inside is calibrated to protect marble, floral installations and rare materials — not adjusted room by room like in conventional homes. This is why actor Shreya Dhanwanthary once revealed, during a fashion shoot inside Antilia, that a request to raise the temperature was politely declined. The explanation was simple: the building’s climate is set for the house, not its guests.

In Antilia, even air follows design rules.

Speculation around the Ambanis’ living quarters has ranged from vastu theories to symbolic numerology. But the real reason, shared by Nita Ambani, is strikingly uncomplicated.

Sunlight. Ventilation. Fresh air.

The 27th floor sits high enough to rise above Mumbai’s densest pollution and noise layers, yet low enough to remain connected to the city’s pulse. From here, unobstructed daylight floods the rooms, and cross-ventilation allows natural breezes from the Arabian Sea to drift in gently.

This level offers panoramic views without the harsh exposure of the very top. It is where elevation becomes comfort rather than spectacle. According to Nita Ambani, the family wanted a home that breathed — not one sealed off from nature by glass and machinery.

Luxury, in this case, meant restraint.

A Private Sky Residence, Not Just A Floor

The 27th floor is not a showpiece. It is a closely guarded family zone shared by the core Ambani household.

This includes Akash Ambani and Shloka Mehta with their children, and Anant Ambani with Radhika Merchant, now firmly part of the next chapter of the family legacy. Access is intentionally limited. Very limited. Think of it less as a penthouse and more as a floating family courtyard — a place designed for togetherness rather than display.

Yes, Antilia Has A Snow Room — In Mumbai

For all its practical choices, Antilia still reserves space for wonder.

One of its most talked-about features is the snow room, engineered to produce artificial snowfall and sub-zero temperatures. On a humid Mumbai afternoon, stepping inside feels like crossing continents. It is indulgent, whimsical, and unapologetically extravagant.

Elsewhere inside the building are spaces that read like a catalogue of modern excess: a grand ballroom, marble pools, a private temple, a cinema, spa and salon floors, multi-level gardens, an ice-cream parlour, and three helipads crowning the structure. Over 600 staff members reportedly keep the residence running with clockwork precision.

And yet, none of it feels random. Antilia is not chaos disguised as wealth. It is curation.

Why The Name ‘Antilia’ Fits More Than You Think

The house takes its name from Antillia, a mythical island once believed by sailors to exist somewhere in the Atlantic — a place of abundance, visible but unreachable.

It is a fitting metaphor. Antilia is one of the most photographed homes in India, yet remains fundamentally unknowable to those outside it. Glass reflects the city, but reveals very little of the life within.

The Quiet Truth Behind The World’s Loudest Home

Strip away the numbers, the rumours, the reels, and one truth remains: even the richest family in India prioritised sunlight over spotlights, air over artifice, and proximity over pomp. Antilia may be a vertical palace, but at its heart, it is simply a home designed around warmth, family, and breathing room — suspended high above a city that never stops moving.

If you were building your own dream home in the clouds, what would you choose?

Or simply a window where the light always arrives first?
