Kevin McCloud meets Tom and Danielle Raffield, whose lifelong passion has been steam-bending wood. They've used the technique to create extraordinary furniture and lighting, but now plan to use it on a larger scale. In an attempt to escape the confines of their tiny gamekeeper's lodge, they have decided to build a wavy wooden house in South Cornwall, completed with curved cladding, twisted furniture and interior walls covered with weathered timber. With a £100,000 budget, the pair have decided to do a lot of the building themselves, and Kevin is on hand to discover whether they're up to the challenge.
