It's the first quarter final and 4 of the winners from the previous 8 heats are now ready to paint, sew and build their way to a gain the first 2 places in the semi-final of the The Great Interior Design Challenge. This time our amateurs are taking on 4 thatch cottages in Milton Abbas, Dorset. Having won a heat already confidence is running high for all our amateurs, but they have to prove they have versatility and new ideas. Built in the 1779 Architectural Historian Tom Dyckhoff explains the fascinating history of this Georgian "model village". Judges Sophie Robinson and Daniel Hopwood will be judging which 2 of our 4 amateurs are good enough to go through to the semi final, and they won't be so lenient this time if their running late or the rooms are unfinished. Our first 4 quarter finalists are 44 year old painter and decorator Johnny , 30 year old Café owner Jordon from South East London, 41 year old vintage homeware designer Sarah from Sussex, and 30 year old design student Charmaine from Harrow. Sarah pushes to deliver her Nordic woodland design and upholsters a whole sofa. Johnny knows he has to give a complete look and finish to his room after focussing too much on his bespoke bookcase last time around, so and aims to create a traditional rustic scheme. Charmaine must show she can be bolder with her designs and works hard to create an autumnal scheme with a huge bespoke cabinet; and Jordan whose last room was a work of grey has to demonstrate he can work with colour, as he works to create one of brightest and colourful rooms seen so far. With such stunning rooms and supportive homeowners, this time around the amateur designers have no excuses and must deliver exciting, but comfortable rooms. They each have 48 hours, £1000 and the help of a builder but only two of the designers will be able go through to the semi final.
