Grand Designs

Kevin McCloud follows a couple who face a race against time to realise their dream. Two years ago, corporate accountant Pep was diagnosed with terminal cancer. But rather than rest and avoid stress, Pep and partner Malene focused their attention on a long-held ambition to build a new house on their land in the Surrey Hills. The plan is to construct a modern take on a Viking hall, inspired by their love of all things Scandinavian and Malene's Danish heritage. But they must build quickly so Pep can enjoy what time she has left in the finished home.

Piers and Emma build the first new listed castle in the UK for 100 years, complete with a tower, moat and futuristic tech. It's the biggest ever Grand Design, so is even their £2m budget enough?

Kevin McCloud revisits Stuart and Rosie Treasurer from Wirral, who he first met in 2016 when they set out to transform a small bungalow from a 1960s dormer into a slick piece of 21st-century architecture. The plan saw the couple decapitate the building and balance a new floating timber box on top to create five bedrooms, spending as little as possible on plumbing, electrics and insulation, but stress levels spiralled when neighbours grumbled at the ultra-modern creation. Nine years on, Kevin sees how Stuart and Rosie are getting on.

Kevin McCloud revisits Greg and Georgie, who in 2019 set out to convert a dilapidated 35-year-old barn in Georgie's parents' garden in Sevenoaks into a peaceful safe haven. It was a highly challenging build involving the painstaking conservation of the existing rotten structure, building a new two-storey internal steel frame and recycling everything they could to stretch their £250,000 budget. But how are they getting on six years since the original show went out?
