Ten budding interior designers compete in a makeover challenge. Michelle Ogundehin tasks them with transforming five luxury apartments in London's Elephant and Castle. They work in pairs, with one designer in charge of the open-plan kitchen-living room, while the other transforms the bedrooms. Each apartment must be targeted towards a different type of tenant, from young couples to older residents. Finished designs must show cohesion between the teammates' schemes and clever use of sustainable materials. With just two days, £1800 and a team of tradespeople to help, the designers begin turning these blank canvases into fresh new takes on urban living.
