A dark, dingy garage is turned into a safe but far from boring place for a girl with Down's syndrome. Elisa and Andy Jones have been renovating it for the last six years but with little success until now.

This week Nick Knowles and the team are in Plymouth. The Wroe family have hit a string of disasters building their two bedroom extension. However their build became insignificant when the family had the heartbreak of losing their baby daughter Imogen aged 15 months. Now back on their feet work has started again but the build is over budget and with the arrival of their new baby David the couple now share their bedroom with him and their daughter Kirsty. The challenge is to give Kevin and Tracey Wroe what they have been desperate for, space for themselves and their family.
