Mumbai has always been where Indian wealth makes itself visible. The city alone accounted for 42 per cent of all luxury home sales in India in 2024. Land scarcity in South Mumbai, where most of the country's most expensive private residences are concentrated, means that trophy properties here are appreciated not only through inflation but through fundamental supply constraints. Altamount Road, a 1.5-kilometre stretch in the Cumballa Hill area of South Mumbai, is home to three of the five most expensive private residences in the country and is widely regarded as India's Billionaires' Row. Below is a list of five of the most expensive homes owned by billionaires.
The only private residence valued higher than Antilia anywhere in the world is Buckingham Palace. Designed by Chicago-based Perkins & Will with interiors by Hirsch Bedner Associates and built between 2004 and 2010, the 27-storey, 568-foot tower owned by Mukesh Ambani on Altamount Road covers 4,00,000 square feet and was valued at USD 4.6 billion in 2023. No two floors share the same design or material—marble, crystals, and mother-of-pearl are the recurring vocabulary, running through interiors that take the lotus and the sun as their structural motifs. The building is earthquake-resistant to magnitude eight on the Richter scale, which required tilting the structure slightly eastward during construction to ensure vertical recovery after seismic movement. A six-floor, 168-car garage has a service station on the seventh floor. There are three rooftop helipads, nine elevators divided among family, guests, and staff, a 50-seat private cinema, a ballroom, a spa, a yoga studio, a dance studio, a private temple, three floors of hanging gardens inspired by ancient Babylon, and a snow room whose walls produce artificial snowflakes—the last of which is either an extravagance or a reasonable response to Mumbai in May, depending on one's perspective. A staff of approximately 600 maintains the building. The Ambani family moved in in late 2011, following a 10-day Vastu purification ceremony.
Price: Estimated value: Rs. 15,000 crore.
The name of JK House comes from Lala Kailashpat Singhania, the grandfather of Raymond Group Chairman Gautam Singhania, and the building rises from the footprint of the family's original ground-plus-two bungalow built in the 1960s. What replaced it is a 30-storey, 145-metre tower—the second-tallest private residence in the world after Antilia, which sits a short distance away on the same street—with 16,000 square feet per floor and a 45-foot marble canopy at its entrance that once held a statue of Queen Victoria and now holds one of Lala Kailashpat Singhania. Five floors are dedicated entirely to Singhania's car collection—Ferrari 458 Italia, Lamborghini Gallardo LP570 Superleggera, Lotus Elise, Nissan Skyline GTR among others—displayed with the precision of a temperature-controlled museum rather than a garage. A separate floor holds a private family museum documenting the Singhania textile legacy. Beyond that: a spa, gym, two swimming pools, a home theatre, a helipad, and floor-to-ceiling glass that offers 360-degree views of the Arabian Sea. The interiors lean toward modern Italian aesthetics, open-plan and material-led.
Price: Valued at approximately Rs. 6,000 crore.
Before Cyrus Poonawalla, Chairman of the Serum Institute of India, bought it, Lincoln House was the official residence of the American Consul General in Mumbai. Before that, it belonged to the Maharaja of Jammu and Kashmir, Hari Singh, until 1957. The heritage bungalow in Breach Candy was purchased by Poonawalla for approximately Rs.750 crore—one of the largest single residential transactions in Indian real estate history at the time. Its value is not in the building's scale but in what the building represents: colonial-era proportions, grounds generous enough to feel like a misprint in the density of South Mumbai, and a provenance that no amount of new construction can replicate. Large columned halls, high ceilings, and a land footprint that simply does not become available in this part of the city anymore.
Price: Current estimated value: Rs. 750 crore and above.
Gulita was a wedding gift—from Ajay Piramal and Swati Piramal to their son Anand on his marriage to Isha Ambani in December 2018. The five-storey, sea-facing property in Worli had been purchased from Hindustan Unilever in 2012 for approximately Rs.452 crore and then fully renovated, engineered by London-based firm Eckersley O'Callaghan. The building received its BMC occupancy certificate in September 2018; over a thousand workers then prepared it in the weeks before the wedding. Spread across approximately 50,000 square feet, Gulita is organised around a grand central courtyard, with triple-height rooms, a diamond-themed design thread running through the interiors, an open-air swimming pool, three basement levels of parking, a private temple, and a lawn and garden opening off the basement level. The decor is predominantly imported; the material palette runs to precious stones. Malabar Hill's trajectory in Mumbai's luxury market since 2012 has pushed its current estimated value well above the purchase price.
Price: Estimated value: Rs. 818 crore and above.
Jatia House is a double-storey heritage bungalow on Malabar Hill—Mumbai's oldest and most politically significant residential address—and its value rests entirely on land, provenance, and the mathematical impossibility of finding anything comparable in a city that ran out of space decades ago. Built in the colonial era, it has columned halls, large rooms with Burma teakwood ceilings, marble floors, Belgian glass windows, a grand ballroom, a central courtyard, a garden with a pond, and grounds that accommodate 500 to 700 guests—proportions that feel implausible in present-day Mumbai precisely because they are. Kumar Mangalam Birla, Chairman of the Aditya Birla Group, owns the approximately 28,000 to 30,000 square-foot property, which has 20 bedrooms and sits on close to an acre of Malabar Hill land. It was acquired at approximately Rs.425 crore—a figure that has appreciated considerably since, given that the supply of colonial-era estate properties anywhere in the city is, for practical purposes, zero.
Price: Estimated value: Rs. 425 crore and above.
