The photos of the interior of the world's first $1 billion home "Antilia" have been revealed.

Nita Ambani, wife of India's richest man Mukesh Ambani, spoke about her 27-storey, 570-foot-tall and 400,000-square-foot home for the first time in an exclusive interview published in the June issue of Vanity Fair magazine.

"We moved in two months ago and then it was going round that we haven't moved in," she told the magazine.

The world's most expensive house "Antilia" is named after a mythical Atlantic island. The house is a 27-storey personal home is located on a sea-facing plot at Altamount Road, Cumballa Hill, South Mumbai, India, and belongs to Mukesh Ambani, Chairman of Reliance Industries.

A photo of one of the rooms published in the magazine shows ceiling-to-floor windows and a big hall with seating arrangement that look likes a five-star hotel lobby. "It's a modern home with an Indian heart," Nita said.

Although the house is 27 storeys high, BBC's Reginato notes that many of the floors are double or triple in height, so the house rises to 570 feet which is equal to a 40-storey building. The house also includes a multi-storey garage, three helicopter pads, a ballroom, a health spa, yoga studio, a theatre, guest suites, a number of terraced gardens and a Hindu prayer room. "Getting my temple right was so important," she said.

The building was designed by Chicago-based architects, Perkins & Will, on the principles of Vaastu Shastra to increase the positive energy. The materials used in the construction of each floors vary widely and no two floor plans are same. It is designed to survive an 8-richter scale earthquake. 

"We made our home right at the top because we wanted the sunlight... so it's an elevated house on top of a garden," Nita added. According to Nita, the interior design was based on the theme of lotus and the sun and is decorated using marble, mother-of-pearl, crystal and rare woods. 

The house is reported to be worth more than $1bn, according to the BBC, and Mukesh Ambani is worth $22 billion, says the Forbes 2012 richest person list.  

Mukesh Ambani's associates have described Antilia as the "Taj Mahal of 21st century India."
