It's the grand final. Two of our best designers have battled their way through sweat and tears to get here. Now just one can be crowned the champion and winner of The Great Interior Designer Challenge. However, the amateurs are going to find it harder than ever to win that coveted title, as in their biggest challenge to date, they will have to complete THREE rooms each in converted apartments in an eighteenth century mock castle in Broadstairs. The designers will have 72 hours across four days in which to complete their rooms but this time their teams will be bigger and they will have a larger budget of £4000 each. However the designers will be tackling and taking on a KITCHEN for the first time ever and our designers will soon find out that working in older properties is certainly not without its challenges. Judging this epic battle will be Daniel Hopwood and Kelly Hoppen, but this time they will be helped and joined by former judge and interior stylist, Sophie Robinson. Nothing will escape these three so the battle will be intense. Both the designers will be tested to the max, clients will be exacting, demands will be challenging and for the designers there is more than just a trophy on the line. Architectural historian Tom Dyckhoff will be exploring the castle and explaining the significance of such a beautiful building in British history. But all eyes will be on the two finalists as only one will be walking away as winner of The Great Interior design Challenge.
