Episode 4

It's the last stage of the contest. Which team will be crowned Lego Masters 2017? First, the remaining teams face their toughest quick-fire build of the competition and their toughest critics - children. The teams then have just three hours to bring the children's inventive stories to life as brick displays - including a robot with an ostrich head, an alien from the planet Zorg, and a monster who devours a chocolate lake. Next, for the Grand Final, the remaining two teams have two weeks and half a million bricks to make their masterpiece. One team makes a human sculpture while the other createa a mythical world. Both builds are revealed to the public at London's Design Museum; where they are judged by The LEGO Group's Matthew Ashton and celebrity guest judge comedian Dara Ó Briain.
