This is the world's most expensive house. Located in Kensington Palace Gardens in London, the house is set to sell for £117 million, which is just over $230 million. US born financier Noam Gottesman is rumored to have sold the house to steel magnate Lakshmi Mittal, who is worth over $50 billion.

Included with the house is Orlando Bloom as the butler, Gordon Ramsay as the chef and Michael Jackson as the nanny. Other highlights include solid gold floors, solid gold walls and solid gold doors. Unfortunately, the roof is made out of tin as they ran out of solid gold.

Apparently, the doorbell consists of the whole London Symphony Orchestra playing Rihanna's "Umbrella" over and over again.
