Grand Designs first appeared on our screens a quarter of a century ago. Now, in this special one-off show to mark the programme's 25th anniversary, presenter Kevin McCloud is taking viewers down memory lane to revisit some of the greatest and greenest designs ever featured, as well as some of the most ambitious ones and the odd disaster along the way.
Reflecting on the huge success of the show Kevin says, "I could never have imagined we’d be on air for 25 years. I thought we'd run out of projects before we got to the end of the first series and that would be enough. I didn’t think people would want to watch people nailing bits of wood together!"
