The main house at Mt Airy is very formal and not really suited for a family with young kids like the Emerys. Catherine and Tayloe take on the challenge of converting an extra bedroom into a casual family room where they can kick back and relax. But just as they are wrapping up the project, they realize they have made a very costly mistake.

The grounds of Mount Airy are massive, but Catherine and Tayloe don't really have a designated place to entertain outside. They want to create an outdoor cooking and dining area complete with a fire pit. Before they start digging in the yard, they must pass inspection from an archeological team. If any significant historic elements are found in the soil, the entire project will be shut down.
