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 meets flying instructor Colin Mackinnon and trapeze artist Marta Briongos and the incredible metal home they're building next to their very own airfield in Strathaven, Scotland. There aren't many people in Britain who can say they own their own airfield. But Colin and Marta Briongos are part of the very select few. The airfield is so important to them, they've decided to live there too. Their ambitious plan is to build an incredible metal sculptural home next to the runway, designed by one of Scotland's most eminent architects and inspired by aircraft hangars. But the difficulties of building their beautiful design soon become apparent. And before the project is barely off the ground they're contending with violent rain, snow, 100-mile-an-hour winds and the worst storms for 100 years. With work slowed down to a snail's pace, what was supposed to be a year-long project heads into its third year.
