Kirstie Allsopp and Phil Spencer look back at brilliant builds and inspiring house-hunts that helped bring harmony to warring couples across the UK. In Wiltshire, Tim and Sonia couldn't decide whether to sell or renovate the home in which Tim had been raised. Tim was ready to move on to a fresh start but Sonia thought with a little work they could start their new chapter without having to move. Over in Warwickshire, Kirstie and Phil met Gill and John, who couldn't decide whether to make their inherited two-bedroom home their own or to sell up and find somewhere else.

Kirstie Allsopp and Phil Spencer recall previous projects involving problematic floorplans that leave properties with poor open plan flow and wasted space. They cite a two-bedroom chalet-style house in the picturesque West Yorkshire village of Clifford and an extended six-bed home in Stockport, Greater Manchester.

Kirstie Allsopp and Phil Spencer consider the dilemma of growing families versus empty nesters, shining the spotlight on two homes that needed adapting for two families at very different life stages. In Swansea, Sarah and Caradog needed to expand their cramped four-bedroom home to accommodate their growing family, while in Caterham, Surrey, Ruth and Ken needed to resolve the debate over their three-storey townhouse following the departure of their children.
