t's the last of the eight heats as three new designers battle it out for the last place in the quarter-final and the chance to win The Great Interior Design Challenge. This time the amateurs are taking on three vast living rooms in Brighton. Architectural historian Tom Dyckhoff explores the history of the homes and the Regency period, as judges Sophie Robinson and Daniel Hopwood decide who has the winning design. The amateurs are 30-year-old café owner Jordon from South London, 37-year-old mum Alice from Lewes in Sussex, and 44-year-old business woman Jenny from Cornwall. Jordon demonstrates his showmanship with his take on Hollywood glamour; Alice creates a fun room with zones for all the family; and Jenny goes for a rustic French country kitchen scheme. But with only 48 hours, £1,000 and one of the largest rooms yet, there's a lot to do and only one designer will be able go through to the quarter-finals. For Daniel and Sophie, with such varied designs to choose from, and everyone rising to the upcycling challenge, it's a tough choice to make.
