Kevin McCloud meets entrepreneur Paul Wilkinson and his wife Amy, who are building a giant new home on a 16-acre plot in Lincolnshire. The superstructure will be comprised of five circular buildings made up of interlocking timber cylinders, linked by raised wooden walkways that hang over a fishing lake. The complicated build proves difficult for Paul's local team, and their ambitious schedule of completing the project in a year soon looks out of reach.
