Take a Look at the World’s Most Expensive Mansion

The world’s most expensive mansion is currently being built in Bel Air. When completed in 2017, the 100,000-square-foot home will require a cool $500 million to call it home, but, as Details points out, that price might actually be a bargain. Aside from all the other amenities that luxurious giga-mansions offer, the new home will come equipped with five swimming pools, a moat, sky deck, casino, nightclub and jellyfish-tank walls. Head to Details to see photos of the under-construction space and to find out how you can get your hands on it.
