The second heat begins. Another group of amateur designers will compete across three knock-out rounds for one place in the quarter final. They are engineering manager Rob, DIY store worker Angelica, ex-visual merchandiser Sarah and textiles lecturer Lucy. They're in the beautiful thatched village of Briantspuddle in Dorset – an unusual Edwardian experiment that presenter and architectural historian Tom Dyckhoff takes a closer look at. The designers must transform a bedroom each in just three days with £1000 and the help of a small team. Rob has a monumental battle, producing all the repurposed furniture and light fittings he's designed in the timeframe. Angelica shows off some brilliant ideas for banishing tatty woodchip walls in her room, but her sleek, hotel chic design must make an impact if she's to impress the judges. Sarah faces an uphill battle persuading her clients to trust her bold choice of floral wallpaper on all four walls of her country scheme. Meanwhile Lucy is taking a big risk bringing her modern design for a teenaged boy to this very traditional cottage. It'll be down to Sophie and Daniel to judge which three designers show the most potential, and which one hasn't done enough to stay in the competition.
