The world's most expensive house is a 27-storey behemoth worth $2 billion (£1.4bn) - though that's a drop in the ocean compared to the wealth of its owner, businessman Mukesh Ambani.
Ambani is known as the wealthiest man in India, and is currently 10th on Bloomberg's global Billionaires Index with a total net worth of $82.8 billion (£59bn).
He's absolutely loaded, having grown his fortune as the chairman, managing director and largest shareholder of Reliance Industries, a Fortune Global 500 company that owns businesses engaged in energy, petrochemicals, textiles, natural resources, retail and telecommunications.

And what does someone with all that money do? Builds himself a 27-storey house, obviously.
Ambani's private residence is the 173m-tall Antilia, which reportedly comes with such essentials as three helipads, a dedicated air traffic control facility, a ballroom and a 168-car garage. It's also designed to withstand an earthquake of 8.0 magnitude on the Richter scale.
Located in Mumbai on Altamount Road, Cumballa Hill, the property was completed in 2010 at an estimated cost of $1 billion.

According to GQ India, Antilia was designed by American firm Perkins & Will and constructed by Australia's Leighton Holdings.
"Sea-facing Antilia stands tall, catching the eye of everyone in the area," the article from May last year says.

"The asymmetrical structure of the building is replete with sprawling terrace gardens. Even though Antilia is built in a way to fit nearly 60 floors, the building has only 27 floors, with extra high ceilings."
Ambani and his family moved into their new home in 2012, but were initially tight-lipped about their luxurious pad, with a 2012 Vanity Fair article saying the house has a 'closed-door policy'.
A spokesman for Reliance Industries said at the time: "It's a private home. There is no reason to discuss it in public."

More recently, however, we've been given glimpses inside the house through the power of social media, with Ambani's wife Nita sharing the occasional photo on Instagram.
She also told Vanity Fair about how the family's living quarters are on the top floors, saying this was 'because we wanted the sunlight'.
In 2014, the value of the property had already climbed to $2 billion, with GQ reporting it is deemed to be the world's most valuable private residence - and the world's second most valuable residential property after Buckingham Palace.
