Summary: In this first episode, Kevin and co profile five amazing country homes on the long-list for the prize: including a large house camouflaged within a hill; a loving restoration in Wiltshire of a prototype modernist retreat; a Scottish home that blends an agricultural exterior with a sleek modern interior; and a slice of spectacular California modernism in Cornwall. Kevin then reveals which of these homes will make it onto the final shortlist.

Summary: Kevin, Zac and Damion profile five homes that are testbeds for architectural ideas, pushing the boundaries for residential design: a cool, concealed house built from glass and concrete; an uber-creative Wallace and Gromit-style house in Edinburgh squeezed onto a disused plot; a gorgeous, low-slung modern home in Cumbria camouflaged with stone; an experimental extension in London with a Japanese flavour; and an elegant house in Buckinghamshire that combines sustainability with glamour. Kevin then reveals which one has made it onto the shortlist and is in with a chance of winning House of the Year 2016.

Summary: Kevin McCloud reveals another five homes vying to be crowned House of the Year 2016. These are houses that create space out of the smallest sites. There's an ultra-stylish one bedroom live/work space with an experimental garden roof; the transformation of a dark mews into a light and airy family home; a beautiful blend of beach living and high architecture in Dungeness; a clever extension in Harrogate; and a narrow beachfront garage that's been made over into a stunning home packed with a large art collection.

Summary: 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.
