Most people have junk, dust and a whole lot of nothing in their basements, but the rich and famous know how to turn redundant space into something magical. Basketball legend Lebron James has his very own subterranean sports bar, complete with pool tables, a movie theatre and a two-lane bowling alley, while rapper 50 Cent is said to have once had a basement nightclub and casino. This luxurious basement can be found in a luxury home in Surrey, UK, and boasts marble floors, a gym, a wine room and a showstopping swimming pool.
