The woodworkers build a bed of dreams that may become the stuff of nightmares for some, and celebrate the fine skill of hand carving in the surprise skills challenge.

The woodworkers make intricate dolls' houses and face a seemingly impossible skills challenge that pushes their joinery skills to the limit.

It's the quarter-final and the five remaining woodworkers turn up the heat and go wild as they take on animal sculptures. They must chainsaw and carve their way through this colossal big build and unleash their inner beasts as they attempt to uncover an animal within the wood, in just two days. Judges Alex de Rijke and Helen Welch also set them a physically demanding skills challenge that takes them back to Viking times, but only one woodworker can win the immunity that will guarantee them a place in the semi-final.

The semi-final finds the final four woodworkers getting tipsy and glamorous with drinks cabinets inspired by a specific decade. They have to craft sliding doors and complicated mechanisms in a bid to make it through to the final. However, judges Alex de Rijke and Helen Welch aren't letting up, as they set a steamy surprise challenge that may bend the woodworkers out of shape.

Mel Giedroyc welcomes the three finalists back to the workshop nestled in ancient woodland on Wales' Glanusk Estate to make their biggest build yet - towering garden buildings. With just two days to build huge creations that would take professionals weeks to make, the woodworkers must give this final build everything they've got. Only one competitor can win, and it's up to judges Alex de Rijke and Helen Welch to decide who is Britain's best woodworker.
