Ten aspiring interior designers on the cusp of turning professional take part in the biggest design challenge of their lives. Competing to win their first official commercial contract, with the Watergate Bay Hotel in Cornwall, the designers face a different commercial brief each week, with their spaces scrutinized by head judge Michelle Ogundehin. This week, Michelle is joined by fashion designer turned interior designer Matthew Williamson. The challenge they set is to transform five upmarket rental apartments in Manchester. Working in pairs, the designers must decorate a living room or master bedroom and a shared home office. They have just two days, £1,500 and two tradesmen to help them get the job done.
