English funnyman Ricky Gervais has upset his London neighbours with plans to build an underground swimming pool in his Hampstead mansion. The Office and EXTRAS creator recently purchased a $3.9 million (GBP2 million) home in the north London suburb and has submitted plans to dig out his basement to his local council. MARTIN HUMPHREY, vice-president of the Heath and Hampstead Society, says, "Mr Gervais has been very good about it, but there is going to be a great deal of disturbance and mess."
