Nick Knowles and the DIY SOS team are in Oxford to help complete a bungalow extension. The Barker family have been trying to build the extension for three years, but a run of disasters have got in their way. Designer Julia Kendell's ambition is a kitchen/diner/lounge area. Her design theme is based on cricket, and the boys are armed with half a kilometre of tongue and groove to help her achieve her vision. It is a stunning reveal, with some original ideas and contemporary twists, but will the team be able to achieve the dream home for the Barker family?
