The Great Interior Design Challenge: In the third and final round of this heat, two designers have proved their talent, but now only one can win a place in the quarter-final. The backdrop for this design showdown is an 18th-century Scottish castle, now converted into apartments. Once again they have just £1000, three days and a small team to make their transformations. Our two designers are following very different briefs in two different reception rooms. One designer has been asked for an elegant lounge and dining room, and has some brilliant ideas for creating sumptuous details on a budget - but with major concerns over their choice of mirrored wall panels, the overall look may fail. Meanwhile, the other designer wrangles to give their high-ceilinged, plain sitting room a steam punk influence. However, running out of wallpaper and struggling with intricate details could threaten the entire project.
