Grand Designs is een Britse documentaire van de zender Channel 4. De serie ging in première op 29 april 1999.
Sommige mensen dromen alleen van hun ideale huis, anderen bouwen het gewoon. Kijkers krijgen de gelegenheid om het hele bouwproces te volgen: van de allereerste schetsen op papier tot en met het daadwerkelijke resultaat. De altijd kritische Kevin McCloud bezoekt de locaties en praat met de eigenaars over hun ideeën en over de problemen die zij tegenkwamen tijdens de realisatie. In Grand Designs lijkt geen enkel huis op het andere, maar wat ze wel gemeen hebben is dat ze allemaal erg bijzonder en opvallend zijn.
Kevin catches up with the story of a daring modernist home in the Andalucian hills in southern Spain.. Ten years ago Gil and Hillary Briffa decided to retire to southern Spain. Rejecting the coastal sprawl around Malaga they found a virgin plot of land up in the Andalucian hills for just £35,000. But instead of building a home like the traditional old fincas nearby, their architect son's design was a confrontational, modernist glass box, surrounded by boldly coloured connected rooms, hidden behind a giant citadel wall. Construction proved stressful. The couple put all their trust in a local Spanish builder who had never built a house like this before. The local residents didn't like it and the mayor tried to get it re-painted white. But if they could just finish the build, it promised to be the coolest retirement home Kevin McCloud has ever seen. Sadly, Gil died a few years ago, but now Kevin returns to meet with Hillary again and to see whether or not their building has settled into its landscape, whether it's still multi-coloured, and to find out just how life is for her as a British widow living up in the Andalucian hills.
