After a tough first week transforming apartments in London, the remaining nine designers return to the design studio in Brighton to discover their next challenge.Welcomed back by host Alan Carr and judge Michele Ogundehin, the designers learn that this week they'll be dealing with some very demanding clients – preschool children! Working in teams of three, the designers are tasked with making over three classrooms of a children's nursery in Oxfordshire, one for babies, one for toddlers and another for three- to five-year-olds. Each classroom must feature areas to accommodate different activities: a calm zone, a creative zone and an imaginative play zone, and safety is key! While some designers worry about where to start, others are relishing the opportunity to unleash their inner child.Helping Michelle judge this challenge is interiors expert and queen of colour Sophie Robinson. When they deliver their verdict, another designer's journey comes to an end, leaving eight designers left to fight another day.
