Grand Designs: House of the Year: Season 4, Episode 3

4 - 3: Extreme Houses

Kevin McCloud, architect Damion Burrows, and design expert Michelle Ogundehin visit four more stunning homes looking to be crowned Riba House of the Year 2018. This time, the theme is Extreme Houses. There's an awe-inspiring set of cantilevered black boxes which push the limits of engineering; a far-flung 21st century crofter's cottage by a Loch in Scotland; a curvaceous minimal concrete home in London; and in Northern Ireland, a sculptural home designed around a single shape - the wedge. Which of them will make it onto the shortlist for the overall big prize?
