In the second round of this heat, the three remaining designers are out to impress working in Kentish weatherboard cottages. This challenge is a huge leap for the amateurs, as each building is grade II listed, with individual restrictions on what can and can't be changed. They'll have £1000, three days and the help of a small team to complete their transformation. One designer struggles with lighting fixtures and fittings in their dark, medieval room – especially as they've controversially chosen to paint the walls lime green. The second designer is putting all their efforts into beautifully crafted soft furnishings – but with the judges accusing them of playing it safe, the decision could backfire. Meanwhile the last designer faces disaster when their client dislikes elements of their scheme, and negotiations on replacement wallpaper become tense. Will they be able to turn it around to keep their place in the competition? Presenter and architectural historian Tom Dyckhoff delves into the history of weatherboarding homes so typical of the region. While it's down to the judges to decide which two designers will go through to the next round, and which one will leave the competition.
