Before anyone else tastelessly suggests it, no, Nick Knowles is not building a new tower block.
What he and his team of builders are doing is help create some buildings in order to assist those who were affected by the fire. In the first of two programmes, Knowles is helping create a new home for the Dale Youth Boxing Club, which had been based in Grenfell before the fire and have since been squatting in a gym. Help for the build comes from volunteers, suppliers and even royalty.
