A couple, Pru and Richard Irvine, decide to build a family home on an industrial site in the Midlothian countryside complete with lime kilns, but are only allowed to do so if they become custodians of the kilns and their house blends in with the landscape. This proves challenging for the pair as they want to build a modern property that could be seen as a blot on the landscape to the locals. The task is made all the more demanding when they underestimate the long hours needed to be a project manager.
