In the last round of this heat, two designers are left battling it out for just one sought after place in the quarter final. They must earn their place by transforming two tiny bedrooms in medieval timber framed bedrooms in Sussex – still with a budget of £1000, a small team to help them and just three days to complete their projects. However working in such small rooms brings a myriad of problems for both designers. The briefs are poles apart. One designer must create a calm and serene Scandinavian inspired scheme – complete with raised built-in bed… but with a client who loves authenticity, and the judges worried about using MDF for the bed, the whole look is under intense scrutiny. Meanwhile, the other designer is working for a 7-year-old boy, delivering a batman inspired fantasy den – complete with bat motif lighting, secret compartment and dark grey walls… if the client's mum agrees. Presenter and architectural historian Tom Dyckhoff looks back at how these timber framed houses were originally put together, while the judges must make the huge decision about which designer shows the skill and talent to become a quarter finalist and who will leave the competition.
