It's the first quarter-final and four of the winners from the previous eight heats are now ready to paint, sew and build their way to a gain the first two places in the semi-final of the The Great Interior Design Challenge. This time the amateurs are taking on four thatch cottages in Milton Abbas, Dorset. Having won a heat already, confidence is running high for all the amateurs, but they have to prove they have versatility and new ideas. Architectural historian Tom Dyckhoff explains the fascinating history of this Georgian 'model village', built in 1779. Judges Sophie Robinson and Daniel Hopwood judge which two of the four amateurs are good enough to go through to the semi-final, and they won't be so lenient this time if contestants are running late or the rooms are unfinished. The amateurs each have 48 hours, £1,000 and the help of a builder, but only two of the designers will be able go through to the semi-final.
