The search for Britain's best amateur interior designers begins with the first of eight heats. Would-be interior designers Sarah, Helen and James take on three large bedrooms in Edwardian homes in the leafy north London district of Muswell Hill. They have 48 hours, £1000 and the help of a builder to interpret and make real the homeowners' briefs. Vintage homeware designer Sarah has given herself a lot to do including upholstering a chair, something she has never done before. Asset manager James has to get the homeowners on-board with his bright colours and artist Helen is hoping to discover an Edwardian gem behind some built-in cupboards. As well as impressing the homeowners, they must also satisfy judges Sophie Robinson and Daniel Hopwood. Only one designer can make it through to the quarter final.
