Lego Masters

In this episode, 48 pairs are whittled down to just eight final teams over a series of challenges. Then, for their first build, the eight teams must create a spectacular brick banquet, including an impressive chair that not only looks the part, but also holds presenter Melvin Odoom's weight.

This week the teams must step it up a gear and make their models move. They have to build a funfair with at least one spectacular supersized mechanical funfair ride, complete with moving parts and characterful stories in miniature form.

Nature is the theme this week, and the remaining five teams are leaving the security of the Build Room and taking their construction skills into the great outdoors. This week's challenge is to create and install a spectacular brick display of living things into a Nature Walk which will include transporting all their fragile models to a woodland in Essex.

It's the final round in the search for Britain and Ireland's most talented amateur Lego builders and 3 teams remain. Only two teams will make it through to the Grand Final where they will get the opportunity to create their dream build with half a million bricks each and one team will be crowned Lego Masters.
