Some artists would settle for a condominium or loft but for Robbie Williams, he used his money to buy a whole building. His $17-million real estate property is located in West London and has 46 rooms in total. The 5-floor building was undergoing three years worth of renovations before the Williams family moved in. After the renovations, the building now had a floor-sized pool, cinema hall, and gym. Just imagine how much he has to pay for insurance and taxes for this property.
