Lakshmi Mittal, the Chairman and CEO of the ArcelorMittal, himself lives at Kensington Palace Gardens, dubbed as London's "billionaire's row" with neighbours including fellow tycoons such as Roman Abramovich and Len Blavatnik, ranked ahead of Mittal in this year's 'Sunday Times Rich List'. Mittal also has another property nearby on Palace Green in Kensington which he bought for 117 million pounds in 2008. At that time it was declared the most expensive home in Britain. The 12-bedroom palatial home was bought for Mittal's son, Aditya, from Israeli-American financier Noam Gottesman. However, Aditya, who is the chief financial officer of the family-owned steel firm ArcelorMittal, and his family reportedly never moved into the new mansion. According to the 'Sunday Times', he may end up making a loss on the neo-Georgian building after it went on the market for 110 million pounds.
