About this programme

8/14. Kevin McCloud follows the progress of Robert and Milla Gaukroger, as they try to add three extensions to a 1980s property overlooking Lake Windermere in the Lake District. Robert has designed his own heating system to achieve maximum sustainability, but the project begins with only £100,000 of the £400,000 budget in place, and he and his family have to move into the existing building while work goes on around them.
