5. Midlothian: The Lime Kiln House

Pru and Richard make plans to build a bespoke family home on an industrial site in the middle of the Midlothian countryside. However, the plot of land, an old industrial site complete with lime kilns, comes with a condition. They can build on it only if they become custodians of the kilns, and more importantly, that the house they build blends in with the landscape.
