It's the semi- final, where two designers will be going head to head for a place in the grand finale, so the pressure is mounting and the stakes are high! The challenge our two designers have to conquer to get there is transforming two rooms in modern town houses in Bristol: one designer will be taking on a master bedroom and a guest room/ craft room and the other amateur will be tasked with redesigning a living room and a bedroom /craft room. Judging them are of course regulars Kelly Hoppen and Daniel Hopwood but this time they are relying on an extra pair of eyes in the form of guest judge Michelle Ogundehin, Editor in Chief of Elle Decoration. The designers will again have two rooms to transform over 48 hours across three days, a team of two builders and two decorators, a budget of £2000 to use for both rooms and again they will both have to complete one room on day two which will be judged by all three judges. Both designers are out to impress but the judges have concerns over the quality of their work, the time allotted and their communication skills to achieve their final schemes. One semi-finalist attempts a very intricate hand painted mural across all the bedroom walls, but can they deliver a precision like finish in the ever decreasing time limitations? Meanwhile a chaise longue could be one designer's downfall and a designer's plans are seriously thrown into question with their demanding client's ever changing needs. On top of this both designers must impress with a surprise challenge as each are tested again with the Creative Challenge.
