The Great Interior Design Challenge

In 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.
