Kevin McCloud visits five houses praised for their use of materials and craftsmanship. A barn conversion in East Anglia, a minimal hymn to brick in Northern Ireland, an eco-terrace in London, a timber based eco-home in the Fens and an extension in Norwich. The winner of the RIBA House of the Year award is finally revealed.

Kevin McCloud visits homes that, along with being nominated for the RIBA House of the Year prize, have pioneered a new architectural style by fusing mock-Tudor, modernism and industrial chic. A home in Derbyshire that experiments with reorganising space, a small-space design in an infill plot, an eco-extension on a historic cottage in Suffolk and a home in London remodelled complete with a mountain on the roof.

Kevin McCloud visits five recently transformed homes that have been shortlisted for the RIBA House of the Year award. A barn renovation in Sussex, a reborn parchment factory in Northamptonshire, an eco-friendly mews house in London, a former cowshed in Dorset and two fused flats in the Kyles of Bute.

Kevin McCloud is joined by architect Damion Burrows, design expert Michelle Ogundehin and conservation architect Natasha Huq to review the properties in the running for the 2022 Royal Institute of British Architects House of the Year award. They begin with five hard-to-build houses, from a playful pink beach house built to withstand fierce winds to a meticulous renovation of a 1960s home in Derbyshire and a DIY eco-home in Stirlingshire. They also visit a difficult-to-build reimagining of a redbrick house in Dorset and a London new-build that faced challenge after challenge.
