It's the final of The Great Interior Design Challenge, and after starting with 24 amateur interior designers we are down the last 2. This time the stakes are raised as each Amateur Interior Designer is given a grand Georgian house where they must re-design the hallway, front room, guest room and childs bedroom. It's a huge undertaking. The money has gone up to £4,400 and they now have 72 hours the help of 2 builders and the help of a decorator. 41 year old vintage home ware designer and mum of 3, Sarah from Sussex, is also bringing along her best friend Maxine to help realise her schemes. This time she has to show her versatility with more modern designs, but with the rooms already in such good design order how will she make a big enough impact. Our other finalist is 30 year old coffee shop owner Jordan from South East London who is bringing along his partner Russell to help with his designs. This time Jordan has a blank canvas – a home stripped of all it's internal architectural heritage, putting it back is a big job, and he needs to show he has fresh tricks up his sleeve. Architectural Historian Tom Dyckhoff guides us around the history of these beautiful Liverpool homes. Daniel Hopwood and Sophie Robinson must judge who deserves to win – it's a tough decision with such different designs on offer. But only one amateur will be good enough to win The Great Interior Design Challenge.
