Grand Designs

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?
