Nick Knowles, Laurence Llewelyn Bowen and hundreds of Warwickshire volunteer builders help Chloe, whose cramped family living room has been her prison for the last two years. When Chloe was 18 years old, doctors diagnosed her with mastocytosis, a rare genetic disorder. As a result, Chloe now requires constant access to oxygen, must be fed through a tube in her chest and is prone to seizures that cause her joints to dislocate and stop her breathing. Chloe currently lives with her mum Susie, stepdad Phil and stepbrother Josh, but the current design of this tired house means her future in the family home is not guaranteed. So to improve Chloe's life and future-proof her care and accommodation, the DIY SOS team redesign the entire house to provide Chloe with independence, thanks to her own self-contained apartment, complete with bedroom, wet room and sitting room. As ever, it's a challenging but fun build, with mismeasurements aplenty and a barrister volunteering as a barista.
