The team find themselves in Kingston-Upon-Thames with grandparents Ray and Linda. The couple have spent the last nine years bringing up their grandchildren after their mother sadly passed away. Twins Nathan and Chelsea, who are now both 14, have grown out of their toy room. They took it upon themselves to contact DIY SOS asking for a dining room in its place, as a thank-you to their grandparents. But it's not just Ray and Linda who are in for a surprise - Chelsea gets a new bedroom and there's a big surprise in the garden for Nathan. So Julia gets busy creating a masterpiece with carpet tiles, Billy gets stranded in Bognor Regis, and Nick tries to skateboard.
