Watch Grand Designs: House of the Year Season 2 Episode 4 Online

Kevin McCloud reveals the winner of the Royal Institute of British Architects House of the Year 2016. First though, there are four extraordinary nominated houses to review, all of which offer a creative response to a tricky site. There is a house stitched into a wall that sits between a Zen courtyard and an English walled garden; a clever, open plan family home built in a former allotment; a house made from a group of red tin pods on a piece of urban wasteland; and a large, glamorous home in Northumberland that creatively pulls northern light through the house.
