Nicki Chapman and Diarmuid Gavin host the last of the heats, in which two pairs of horticultural designers are challenged to create a garden for Focus Birmingham Day Care Centre, an establishment which offers support and activities for people with severe physical and visual disabilities. The episode pits two recent garden design graduates who have never collaborated on a project before against a team with years of experience and the awards to show for it, who each have a budget of £5000 to create something spectacular.
