Reliance Industries Ltd, which is run by Mukesh Ambani, has bought a beachfront home in Dubai for $80 million.
The villa on Dubai's Palm Jumeirah was bought for Anant Ambani earlier this year. The deal is said to be the largest ever in the UAE city.
The beach-side villa in the palm-shaped artificial archipelago features 10 bedrooms, a private spa, and indoor and outdoor pools.
Dubai has been the market of choice for India's wealthy and others since the government there offers 'golden visas' and relaxes property ownership rules.
Bollywood actor Shahrukh Khan, British player David Beckham, and his wife Victoria are among Ambani's new neighbours.
The Ambani family has been expanding their real estate holdings with posh properties in exotic locations.
Akash Ambani, the chairman of Reliance Jio Infocomm, bought a $79-million UK mansion last year.
The Dubai transaction was kept quiet, and the property will be owned by one of Reliance's offshore corporations.
Antilia, a 27-story tower in South Mumbai, will remain the Ambani family's private residence.
