10 most expensive homes

 The world's most expensive house is in London and it's not surprising that it is owned by the Queen of England! The cost of the most extravagant home which is, in this case even a palace than a million dollars, can be soaring to $1 billion. Consider it ironic or fact being more real than fiction but the second-highest cost house in the world is in India and is owned by Mukesh Ambani. The 27-storey Antilia located in Mumbai's Cumballa Hill, was built in the year 2010 at an estimated price of $1-2 billion. Since the Buckingham Palace is Crown property, Ambani's Antilia is the highest-priced private residence anywhere in the world. A few uber-rich buyers, such as Brazilian-born Philanthropist Lily Safra, purchase historic estates and then renovate it to suit their tastes as if they were building their own personal Helipad. Others go further and construct a new palace like the Villa Les Cedres in the French Riviera, which was built for King Benedict. We've compiled the following list of the priciest residences in the world. Some are so large that they need their own pin number. Are you skeptical? Take a look at 10 of the most expensive houses below.
