Grand Designs: House of the Year - Season 4

Kevin McCloud visits homes in the running for the 2018 Royal Institute of British Architects House of the Year, including a magnificent monolithic dark-rendered block in London, a controversial, cutting-edge glass modernist building in Henley, and a north London townhouse filled with Nicaraguan mahogany.

Kevin McCloud, architect Damion Burrows and design expert Michelle Ogundehin visit five more inspiring homes in the running for the 2018 Royal Institute of British Architects House of the Year, including an old Victorian gin distillery in east London transformed into a remarkable modern home, and a turn-of-the-century farmhouse in Devon given new life mixing the traditional with the contemporary. The team also visit a Grade II listed house in Bath, a derelict farmhouse over 400 years old, and a house with a mirrored library at its centre.

Kevin and his fellow judges visit an awe-inspiring set of cantilevered black boxes, a far-flung crofter's cottage, a curvy concrete property, and a wedge house

Kevin visits homes on the longlist that use materials in interesting ways, before revealing the overall winner of House of the Year 2018
