A DEVELOPER is threatening to fill in a homeowner's garden pond...because its own contractors put a boundary fence in the wrong place. Christopher Doyle, of Arbour Close, Lower Cambourne, told The Hunts Post that he has been in dispute with Bovis Homes since 2007 after it was discovered part of his pond was on land owned by Cambourne developers, MCA. Mr Doyle created the pond at his new home to pursue his love of wildlife and said it is home to frogs and newts. He has been told by Bovis that if he wants to keep the pond he must retain it for 20 years or have it filled in. But Mr Doyle believes that agreeing to keep the pond for 20 years could prevent him from selling his home in the future.
