Billionaire businessman, Mukesh Ambani had not moved into his new house in Mumbai even after it was completed last year, sparking many rumors about why he is yet to occupy the lavish building.

As the extravagant 27-story new house remains vacant, there are rumors that the elder Ambani is keeping away from the home named, Antilia because the building does not conform to the ancient Indian architectural doctrine known as Vastu Shastra.

Mukesh Ambani had well as his spokesman has declined to comment on the matter, leaving much room for rumors and peculations in the media. The house, which is one of the most expensive to have been built, has three helipads, six floors of parking and several floating gardens.

Reports suggest that the building is used by the family to invite friends for dinners, movie screenings, but the family leaves for Sea Wind, their 14-story apartment tower at the south end of the city that Mr. Ambani and family share with his mother and his brother, Anil and his family.

Tushar Pania, a spokesman for Mr. Ambani's company, Reliance Industries dismissed speculation by saying that "It's a private home. There is no reason to discuss it in public." He simply added that the family lived in both the places.
