Kevin McCloud looks at the transformation of a derelict mill cottage in Northumberland into a contemporary family home, the longest-running project ever featured on the programme. Stefan Lepkowski and Annia Shabowska began work in 2006, and their ambitious plans involved restoring the Georgian building, reconstructing a watermill and adding a steel-and-glass atrium, but their budget of £250,000 was completely inadequate.
