- Converted Leisure CentreE1
Converted Leisure CentreIn the first round of the first heat, the group of amateurs taking on the design challenge are youth worker Jane, actress Sharon, doggie day carer Holly and ex-textiles salesman Frankie. They must transform abedroom each in a modernist former leisure centre in south London - one of presenter and architectural historian Tom Dyckhoff's favourite buildings in the UK. Jane has a nervous wait using concrete to make elements of her modern Scandi scheme, and is even more anxious to find out if her exacting client likes her scheme. Sharon is being bold with colour to answer a Bloomsbury-inspired brief, but she may have gone too far for her homeowner. Holly gives herself way too much to do - transforming a kid's bedroom with loads of craft projects, including creating a selfie booth for her young client. Meanwhile, Frankie faces disaster after deciding to upholster huge parts of his Japanese-inspired design, including the wardrobe. Can he finish it to his own high standards? They each have a thousand pounds, three days and a small team to help deliver their schemes. With few existing design features in the rooms and high expectations from their clients, the judges must decide which designer hasn't done enough to stay in the competition. - Weatherboard CottagesE2
Weatherboard CottagesIn the second round of this heat, the three remaining designers are out to impress, working in Kentish weatherboard cottages. This challenge is a huge leap for the amateurs as each building is grade II listed, with individual restrictions on what can and can't be changed. They'll have £1,000, three days and the help of a small team to complete their transformation. One designer struggles with lighting fixtures and fittings in their dark, medieval room - especially as they've controversially chosen to paint the walls lime green. The second designer is putting all their efforts into beautifully crafted soft furnishings - but with the judges accusing them of playing it safe, the decision could backfire. Meanwhile, the last designer faces disaster when their client dislikes elements of their scheme, and negotiations on replacement wallpaper become tense. Will they be able to turn it around to keep their place in the competition? Presenter and architectural historian Tom Dyckhoff delves into the history of weatherboarding homes so typical of the region. It's down to the judges to decide which two designers will go through to the next round and which one will leave the competition. - Scottish CastleE3
Scottish CastleIn 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. Presenter and architectural historian Tom Dyckhoff discovers more about the history of this mysterious castle, built as a fortress-like folly where things aren't quite what they seem. It is down to the judges to decide which designer has displayed enough skill and talent to go through to the quarter-final.
