The team is in Frimley in Camberley to help the Oxford family - Lisa, Andy and son Jordan. The Oxfords had just started a double-storey extension on their property when Lisa started getting terrible headaches. Shortly after she was diagnosed with brain cancer which left her unable to drive or walk. Husband Andy took two years off work to nurse her and look after Jordan. There was no time or money to finish the extension and without the extra space the whole family had to share the same bed. It was time to call in DIY SOS. Nick Knowles, designer Julia Kendell and the rest of the team turn up to complete the extension and create a fabulous bedroom for Lisa and Andy. But they don't finish there. Inspired by the plight of the family, they have a couple of extra surprises in store - and still have time to celebrate Lisa's birthday.
