The woodworkers make a supersize creepy crawly and use all their canine cunning to build a house for a four-legged friend. Who will the judges think is top dog?

Mel Giedroyc hosts the semi-final, in which the contestants must create a hanging chair supported by a robust frame that captures the essence of a favourite holiday destination. The skills challenge requires them to recreate an exact replica of a chair leg on a pole lathe, before judges Sophie Sellu and Tom Dyckhoff decide who will be going through to next week's final.
