Grand Designs S23E03 - Episode 3

Kevin McCloud meets Dorran, who has taken on the ambitious task of building a super-modern underground home on a hill outside Canterbury. He entrusts the work to a team of contractors, but when delays and rising costs force him to take charge of the build himself, Dorran faces the biggest challenge of his life, juggling his time between the site and his work as a ship's master out on the North Sea. However, having promised the house to his wife and children, he knows that failure is not an option.
