The Big Build - Dartford

Scott Russell and Jenny Watts got together when they were 16 years old. Twenty-two years and three boys later, they are now a family of five. Charlie, their third son, was born with severe disabilities - spastic quadriplegic cerebral palsy and global developmental delay. He needs around-the-clock care, which Jenny has given up work to provide.

Since he was born 13 years ago, they have struggled in a two-up, two-down end-of-terrace home, and Charlie faces going into care because they simply cannot keep him at home. Carrying him upstairs is a daily battle, and the older boys, Danny and Bradley, are crammed into tiny converted attic rooms.

In the biggest build ever on an individual house, Nick, the boys and Naomi Cleaver rebuild the whole of the downstairs as well as remodelling the rest of the house to provide a more suitable home to bring Charlie up in and keep him at home with his family.
