It's the fifth of our 8 heats as 3 new designers battle it out for a place in the quarter final and the chance to win The Great Interior Design Challenge. This time our amateurs are taking on the toughest of makeovers – 3 kitchens. They will be painting, tiling and creating their own designs in three 1960's homes in a cutting edge Estate in Ashstead, Surrey. With only 48 hours, £1000 and the help of a builder, the Amateur designers will need to manage their budgets and homeowner expectations if they are to get their schemes finished on time. But 24 year old young mum Kimberly from Bicester in Oxfordshire has the added pressure of having to fit appliances recently purchased by her homeowners into her scheme for a bright 60's kitchen. Housewife, 54 year old Anna from Chigwell, has concerns over tiling her Shaker Kitchen , and 39 year old Julia from Nottingham, needs a steady hand to transform a dark shiny Kitchen from black to white. There's a lot to do and only one designer will be able go through to the quarter finals. Architectural Historian Tom Dyckhoff discovers the history of these unique Span homes and the architect behind the utopian vision of his estate, as Judges Sophie and Daniel decide who has the winning design.
