Phil Spencer travels back to Cambridgeshire to catch up with a couple he and Kirstie Allsopp first met three years ago when they were struggling with what to do with their three-bed semi. Amber Brammah, who was leading fitness classes from the garage, wanted a new house with more room to run her business, while ecologist husband Martin preferred the idea of renovating. Having made their decision, how have things changed in the 36 months since?

Kirstie Allsopp and Phil Spencer remember parents-of-three Carly and Phil, who had run out of space in their High Wycombe home. However, while Carly wanted out, husband Phil was confident Kirstie could come up with a renovation solution. Plus, Staines couple Nitasha and Nikunj, whose dormer bungalow presented the experts with one of their biggest challenges yet.
