Kevin meets Mike and Sarah, who bought a remote smallholding in the Derbyshire Dales, somewhere to rear animals and provide a home for themselves and their elderly parents. Kevin follows the couple as they set out to build a 21st-century version of a historic Derbyshire longhouse. Enormous, corrugated and with a highly complex roof shape, it was never going to be an easy build. But soon they face delays and their schedule begins to slide. However, that is nothing compared with the problems of a more personal nature that hit the project.
