For the last eight years, Sarah Beeny has been guiding budding property developers through the renovation game. Many failed to listen to her well-grounded, hard hitting advice but often their bad decisions were saved by a rising property market. But now with the housing market down turn, and lending still in crisis, there's never been a harder time to develop. In this episode with Paul and Karen Clayton in Bristol, it's not a case of will they make a loss on their conversion of a Grade 2 listed house, just how much? Add to that a nine month delay while they battle with the conservation office and this turns into a truly tortuous journey. Meanwhile in Faversham Kent, Robey and Jo Hillard's plans to develop a Grade 2 listed Oast House are also a complete disaster. Sarah has to turn them on their head to save the Hillards from financial ruin and keep conservation happy.
