The ex-Utah prosecutor David Leavitt and his wife Chelom have always dreamed of owning a Scottish castle—not a welcoming white limestone chateau in the Loire Valley, but a brutal and austere baronial mansion on a foggy loch. Suddenly, just such a castle came on the market. The 19th century Knockderry Castle on Loch Long was up for grabs and it was now or never. Although the castle can't be described as a centuries-old building, it is a very challenging project. Restoring Knockderry will take a lot of effort: David and Chelom have to take care of the water, electricity, and sewage systems. They have to make the roof waterproof, repair the doors and windows, and take care of the garden, which has been neglected for decades. From the outside, the building looks perfectly intact, but inside, it is nothing short of a ruin, unsuitable for living. The Leavitt family is inspired to bring through the restoration project and make the imposing Scottish residence with its stunning, if somewhat gloomy, lake view their home, and maybe a little more than that!
