Grand Designs: House of the Year Season 6

In the first programme, Kevin and his co-presenters, architect Damion Burrows and design expert Michelle Ogundehin, visit five breathtaking houses competing for a place on the shortlist - a 1960s- inspired water tower in rural Norfolk, a 21st-century addition to a Victorian London street, a sleek beach house beside a busy south coast boatyard, a 14th-century fortress in Cumbria with a radically contemporary interior and a Georgian farmhouse with an angular, space-age extension

Kevin McCloud, Damion Burrows and Michelle Ogundehin visit five properties demonstrating exceptional use of materials and craftsmanship. They include a bold contemporary barn, forged from corten steel and concrete, a small urban house squeezed into a plot the size of a London Tube carriage, and a Scandi-Scottish lochside bolthole, hewn from Highland stone and Danish oak. The others are a wooden wonderland extension in east London and a Surrey home with an extraordinary engineered timber roof

Kevin McCloud, Damion Burrows and Michelle Ogundehin visit five properties that solve problems, including a modernist riverside house designed to withstand extreme floods, a modular timber home that elegantly resolves the challenges of building in a remote environment and a house that deploys discreet camouflage to blend into its overlooked setting. The others are a pared-back barn conversion that neatly sidesteps the pitfalls of restoring agricultural buildings and a Japanese-inspired house that proves a standard budget need not be an obstacle to building a bespoke home

Kevin McCloud, Damion Burrows and Michelle Ogundehin visit the final five properties, one of which is added to the shortlist, before the winner is announced. This week they focus on houses that reinvent beloved types of building, including a 21st-century reboot of the classic Kentish oast, a low-key eco-home in Devon which turns the idea of the country house on its head and a cool contemporary reimagining of the suburban family house in Surrey
