It's the second of 8 heats as 3 new designers battle it out for a place in the quarter final and the chance to win The Great Interior Design Challenge. This time our amateurs are taking on 3 knocked through sitting rooms in neighbouring homes in a Terrace in Salford. Architectural Historian Tom Dyckoff discovers the history of the homes and the workers they were built for, as Judges Sophie and Daniel decide who has the winning design. Housewife, 65 year old, Susan, is hoping her paint effects will win favour; while financial Lawyer Nigel is banking on some funky wall transfers; but for mum Lynne it's hard work persuading her homeowner that her ideas will work. With upcycling challenges and schemes to pull together the designers have got to convince everyone that they have what it takes to be an interior designer. But with only 48 hours, £1000 and the help of a builder there's a lot to do and only one designer will be able go through to the quarter finals.
