In heat one's final showdown, the last two pairs must give everything to secure their place in the grand final and move closer to winning their dream chateau in France. Max McMurdo raises the stakes by taking them to the remarkable Château de Lalacelle, where they face their toughest challenge yet - planning and hosting a real event for real guests. With high expectations, tight timings and the pressure of performing in a working chateau, only the pair who deliver creativity, organisation and confident execution will progress.

Donna and Paul Newman join head judge Max McMurdo to give their thoughts on the attic snugs, scrutinising everything from layout choices to atmosphere and finish, before the first elimination of the second heat takes place.
