Sezon 4

Ten budding interior designers are challenged to transform luxury apartments in London’s Elephant and Castle. Hosted by Alan Carr.

Working in teams of three, the designers make over three classrooms of a children's nursery in Oxfordshire.

Each designer must make over a hotel room at a five-star golf and spa resort on the banks of the River Clyde in Scotland.

Working in teams of two, the six remaining designers transform three independent shops in Harrogate.

The five remaining designers set to work on their smallest spaces to date: five 1930s beachside chalets in Eastbourne. Laurence Llewelyn-Bowen is this challenge's guest judge.

Romance is in the air as the quarter-final challenge involves wedding accommodation on the banks of Rutland Water in the East Midlands.

The three remaining designers return to Brighton to discover their penultimate challenge – a hair salon makeover in Bristol.

The remaining two designers go head-to-head to win a life-changing contract to redesign a top London cocktail bar.
