The team visit Edmonton, North London, to help the Parenti family. They undertook extension and renovation work on their house four years ago, but a falling out with the builder forced dad Stephen to step in and do it himself, with semi-disastrous consequences. After spending mum Fillippa's inheritance money the house is still in chaos, with a collapsed ceiling forcing their three teenage daughters Cristina, Daniella and Sophia to share a single box room. Nick Knowles, designer Julia Kendell and the rest of the team descend on this chaos to transform the wreckage into three stylish bedrooms for three very different sisters, giving them a space all of their own and ease the pressure on mum and dad.
