Most Expensive House: Antilia

Price: $500,000,000 – $700,000,000

Though not a home in the traditional sense, Antilia is the name given to the residence of Mukesh Ambani, India’s richest man (at ~$23,000,000,000 net worth), who spent an unspecified amount, projected to conservatively be between $500,000,000 – $700,000,000, constructing this 27-story, 400,000 square-foot monolith in Mumbai, India. Containing, six underground parking floors (with space for 168 cars), three helicopter pads, a spa, terraced gardens, a ballroom, a 50-seat theater, and requiring a 600-person staff to maintain, Antilia is actually claimed to have risen in value to the $1,000,000,000 mark as the result of rising property values in south Mumbai.
