Most Expensive House

In 2010 Antilla Mumbai overtook Villa Leopolda to the title 'the worlds most expensive house'. It is in fact the world's first billion dollar house. A custom-build 27 story towering mansion, Antilla in Mumbai is the home of the world’s 5th richest man called Mukesh Ambani, head of Indian petro-chemical giant Reliance Industries, which is India’s most valuable firm by market capitalization.

1 Billion dollars! If you could get someone to make the loan at current standard (US) jumbo mortgage rates, the monthly payment on a 30-year loan would be about 12.5 million dollars. Of course, a $2 billion loan is not going to go into the standard mortgage market, even for jumbo loans.

With double height ceilings, ballrooms, crystal chandelier ceilings, retractable stages, and 600 servants, there is no other home on earth that compares to the 570 feet tall Antilla.


A spate of green skyscrapers have shot up in the last few years, as people learn that buildings account for more CO2 emissions than any other single source. At the same time, we’ve seen a rise in greenwashing by companies recognizing the market value of green and making false claims to fit the category. In an exemplary meeting of these two trends, we have just discovered a building in progress in Mumbai that calls itself the greenest of all the buildings in the Maximum City of 13 million people. If ever there were a literal interpretation of a deceptive green façade, this is it.

Renderings of the 27-story Antilla building depict a highrise that couldn’t be greener. It’s covered in foliage, with living walls enclosing all four sides, hanging gardens and green rooftop. Just a few days ago, the architects boasted about its environmental features – primarily that the walls of plants will increase green space and combat urban heat island effect. But look behind the green façade, and as far as we can tell, there’s nothing else sustainable about the materials or construction. Architecture firm Perkins + Will doesn’t include the project on their site, but this week mentioned no other green features besides the literal green.

The Antilla is being built for Reliance Industries Ltd, India’s largest private sector enterprise (with revenues exceeding $25 billion), and the Ambani family, who own the company. Reliance is a petrochemical corporation whose earnings come from exploring, producing, refining and marketing oil and gas. They are the world’s largest producer of polyester fiber, and a runner-up for several others.

The building will stand on Mumbai’s Altamount Road, where real estate costs as much as $1800/square foot. Although Mumbai is the densest city in the world, with almost 30,000 people per square kilometer, this 500+ foot tall building will only be 27 floors where normally a building of this height would be 60, so that each floor can have exceptionally high ceilings, and 35,000 square feet of the entire building area will be the residential quarters of the Ambani’s.


More Antilla Mumbai Facts


  1. 3 helipads on top. Mumbai corporation has not given permission for making this operational yet.
  2. Hanging gardens within the structure
  3. Swimming pool within the structure
  4. A two storey Health centre
  5. Parking space for 168 cars (6 floors). I initially thought that meant there will be a mini office in the building but apparently that is not the case. All these cars will belong to Mukesh Ambani! Just in case you are interested, he drives a 5 crore Maybach now.
  6. A floor exclusively for servicing these automobiles within the building.
  7. A floor for Home theatre – sitting capacity of 50
Most absurd of all, the house will have a staff of 600 (sic) to do the maintenance activities. That gives a ratio of 1:100 for people living in the house and those who are paid to take care of it. The six lucky ones are the man himself, his wife, his 3 children and his mother Kokilaben. The family will be moving in from their old home ‘Sea Wind’ which was a 14 floor building at Cuffe Parade.
