New Delhi, january 16, 2026: In the world of ultra-luxury real estate, few addresses command as much intrigue as Antilia. Valued at a staggering ₹15,000 crore ($2 billion), the 27-storey residence of Mukesh Ambani, Chairman of Reliance Industries, stands as a vertical marvel on Mumbai’s elite Altamount Road.
While the world marvels at its architecture, a fascinating detail often resurfaces: the sheer scale of the energy required to keep this “Godzilla-sized” mansion running. When the family first moved in, the initial electricity bill didn’t just set a record; it left the nation in a state of shock.
When Mukesh Ambani, Nita Ambani, and their children—Akash, Anant, and Isha—officially shifted to Antilia in 2010, the first monthly power bill reportedly amounted to ₹70,69,488.
To put this astronomical figure into perspective:
Antilia is not just a home; it is a self-contained ecosystem designed to function like a world-class hotel. The energy demand stems from several high-tech features:
Despite having 27 floors, the Ambani family—including Akash with his wife Shloka and children, and Anant with his wife Radhika Merchant—primarily resides on the top six floors. Nita Ambani has previously shared that they chose the upper levels to ensure ample natural sunlight and better ventilation.
Each floor is designed with a unique theme, utilizing rare materials like marble, crystals, and mother-of-pearl. The design follows the “Sun and Lotus” motif, ensuring that no two floors share the same layout or materials.
While critics often point to the opulence, supporters view Antilia as a testament to Indian engineering and business success. Designed by Chicago-based architects Perkins & Will, the building can even withstand an 8.0 magnitude earthquake, making it one of the safest structures in the city.
For the Ambanis, Antilia is more than just a house; it is a legacy project. While the monthly ₹70 lakh power bill might seem like a fortune to most, for the residents of India’s most expensive home, it is simply the cost of maintaining a landmark that defines the Mumbai skyline.
