Royce will begin expansion work on its UK production factory next month, partly driven by the Middle East's demand for bespoke vehicles. In August, Rolls-Royce announced an expansion of its bespoke operation to meet growing demand from the region where most of its clients are based. Now, the company said it is also about to expand its manufacturing facility in Goodwood, Sussex, partly due to this demand. More than half of clients who specified a Rolls-Royce Ghost in 2011 turned to bespoke personalisation, the car firm said in a statement. The 107-year old company sold 23 percent more cars in the Middle East last year compared to the same period the previous year, the firm said earlier this month. In 2011, the company's Middle East arm exported its most expensive car to the region, valued at $1m due to its “high bespoke” design. In total, 56 percent of Ghost and Ghost Extended Wheelbase models sold around the world featured bespoke design in 2011
