It's the second round of the competition and three previous winners must up their game if they are to win a place in the quarter-finals of The Great Interior Design Challenge. They have just three days and £1,000 to transform the reception rooms of three Edwardian houses in Wimbledon, London. After showcasing his raw talent in the first round, deputy restaurant manager Jack aims to show the judges his refined side with his classic Edwardian scheme. Actor Michael has created an unusual treasure hunt in his room for his homeowners' son, but will it have the edginess that the judges are looking for? And college lecturer Fiona must demonstrate her creativity, striking a balance between feminine and masculine in her gentlemen's club themed room. Architectural Historian Tom Dyckhoff delves into the history of the handsome Edwardian houses, in what would once have been a peaceful village outside London. While judges Sophie and Daniel must decide which two designers have done enough to win a place in the quarter-finals… and which one will be leaving the competition.
