#8 Kensington Palace Gardens, London, UK
Another Kensington Palace Gardens, London, UK. but this time not a Mittal. Uber expensive real estate isn’t limited to successful males. Tamara Ecclestone, daughter of Formula One billionaire Bernie Ecclestone, got her piece of the exclusive Kensington Palace Gardens for only $70 million in 2011. Of course, after she added some personal touches like a $1 million Amazonian crystal bathtub, a spa for her dogs, a private bowling alley, and a subterranean swimming pool, the value of the 55 room mansion soared.
