Antilia is the residence of the Indian billionaire businessmanMukesh Ambani and his family.[3] It is located onBillionaires' Row inMumbai.[4] Built from 2006 to 2010 at a cost of nearly US$2 billion,[2][5][6][unreliable source] it was valued at US$4.6 billion in 2023.[7] It is the most expensive residence in India and one of the most expensive and largest private homes in the world.[8]
It is designed to withstand amagnitude eight earthquake.[9] The top six floors are private residential areas. The structure's design incorporates the lotus plant and the sun.
The structure is 27 storeys, 173 metres (568 ft) tall, over 37,000 square metres (400,000 sq ft), and with amenities including a 168-car garage,ballroom, nine high-speed lifts, a 50-seat theatre,terrace gardens,swimming pool,spa, health centre, temple, and a "snow room", which produces snowflakes from its walls.[10][11]
It was constructed between 2008 and 2010.[5]
In 2007, due to a sustainedreal-estate bubble in Mumbai, Ambani's unbuilt house and the 4,532-square-metre plot on which it was being erected were already estimated to be worth more than US$1.2 billion.[6][unreliable source]
In 2014, it was considered the world's most expensive private residence, costing between US$1 and US$2 billion to build.[2]
As of 2023, it was valued at $4.6 billion,[7] with the averageannual growth rate of home prices in Mumbai from 2010 to 2020 at 11.2 per cent.[12] Prices in Mumbai increased by 100 per cent[13] in 2006 and 19 per cent[14] in 2012.
The 4,532-square-metre (1.120-acre) land on which Antilia was built, previously housed an orphanage called Currimbhoy Ebrahim Khoja Yateemkhana (Kareembhai Ibrahim Khwaja Orphanage)[15] belonging to a charity run by theWaqf Board. The orphanage had been founded in 1895 byCurrimbhoy Ebrahim, a wealthy shipowner.[16] In 2002 the trust requested permission to sell this land. The charity commissioner gave the required permission three months later. The charity sold the land allocated for education of underprivilegedKhoja children to Antilia Commercial Private Limited, a commercial entity controlled by Mukesh Ambani, in July 2002 for₹210.5 million (US$2.5 million).[17] The prevailing market value of the land at the time was at least₹1.5 billion (US$18 million).[18][19][20]
The sale was in direct contravention[21] of § 51 of theWakf Act[22] which requires that any such sale of land should be done after the permission of theMaharashtra State Board of Waqfs. TheWaqf ministerNawab Malik opposed this land sale, as did the revenue department of theGovernment of Maharashtra. Thus, a stay order was issued on the sale of the land. The Waqf board also initially opposed the deal and filed aPIL in theSupreme Court challenging the trust's decision. The Supreme Court, while dismissing the petition, asked the Waqf board to approach theBombay High Court. However, the stay on the deal was subsequently vacated after the Waqf board withdrew its objection.[citation needed]
In June 2011, the Union government asked the Maharashtra government to consider referring the matter to theCentral Bureau of Investigation.[23][24][25][26]APIL was filed a decade later by Abdul Matin, against the orphanage and the Charity commissioners permission.[27] As of 2018, the case was being heard by a special bench of the court.[28][29]
The building was named after the mythical Spanishphantom island ofAntillia.[30]

The building was designed by the American architecture firmsPerkins & Will,[1] based inChicago, andHirsch Bedner Associates, based inLos Angeles. They were consulted afterNita Dalal Ambani was impressed by the contemporary Asian interiors at theMandarin Oriental, New York, also designed by them.[33]
The building plan was approved by theBrihanmumbai Municipal Corporation in 2003,[34] and construction started in 2006 withLeighton Asia initially taking charge, and completed by B. E. Billimoria & Company Ltd.[35] The architects altered floor plans and design concepts as the construction of the building progressed.[33] The home has 27 floors with extra-high ceilings. (Other buildings of equivalent height may have as many as 60 floors.)[36] The home was also designed to survive an earthquake ofmagnitude 8.[37] It is considered by some to be the tallest single-family house in the world, but others disqualify the Antilia because it includes space for a staff of 600.[38]
The interior design uses the shapes of the lotus and the sun. These two features are repeated throughout the building using crystals, marble, andmother-of-pearl.[39] However, no two floors use the same materials or plan, the idea of the design is of consistency, but not repetition.[33]
The building has threehelipads; however, they are not operational. The helipads have to be certified airworthy in India by the Director-General of Civil Aviation (DGCA), and have yet to receive approval from the central defence and environment ministries.[40]
The housewarming was held in November 2010. Still, Ambani did not immediately move in for fear of "bad luck".[41] In June 2011, almost 50 renownedpandits were invited to conductpujas and addressvastu issues in the building, after which the Ambanis took up residence in September 2011.[42][43]

Before construction, the value of the plot and the unbuilt house was estimated at more than US$1.2 billion.[6][unreliable source] During planning, the house was expected to be the world's largest and most expensive home, with a cost of about US$2 billion.[33]
In 2014, it was considered the world's most expensive private residence.[2]
On 10 July 2017, a fire broke out on the ninth floor, and it was extinguished within a few minutes. Six firefighters reached the building within 10 minutes of getting the call. However, the fire was extinguished by Antilia staff before the fire brigade team arrived, using a small line of fixed firefighting systems and fire extinguishers. The fire was confined to the4G antenna and plastic framing of the vertical garden.[44]
On 25 February 2021, a car containing 20explosive gelatin sticks and a threatening letter targeting the Ambanis was found near Antilia. The car was parked about 400 metres from the building onCarmichael Road bordering Altamount Road. A security officer at Antilia called the police control room about the suspicious vehicle, and the police rushed to the scene, joined by the bomb detection and disposal squad. After the sniffer dogs detected explosives, the bomb squad removed the gelatin sticks, which were found not to be assembled and had no battery or detonator.[45] The probe was led by Mumbai's crime intelligence unit head,Sachin Vaze. The case was handed to theNational Investigative Agency, which discovered that Vaze was himself involved in this incident, and he was arrested.[46]
Tata Group former chairmanRatan Tata said Antilia is an example of rich Indians' lack of empathy for the poor.[47] Tata said, "The person who lives in there should be concerned about what he sees around him and asking how he can make a difference. If he cannot, then it's sad because this country needs people to allocate some of their enormous wealth to finding ways of mitigating the hardship that people have.[47] It makes me wonder why someone would do that. That's what revolutions are made of."[48]
