Milton Grigg seamlessly incorporated many Jeffersonian elements into
his renovations and additions at Edgemont. Among them are two
underground passageways with lunette windows that lead to a pair of
dependencies he designed. They contain sitting rooms, bedrooms, baths, and kitchen areas. Sheltered from the elements, the symmetrical links between the main house and its outbuildings borrow a design concept Jefferson employed at Monticello and on the Lawn at the University of Virginia.
In addition to the twin dependencies attached to the main house, other dwellings on the property include a stone and weatherboard farm manager’s house, a cabin on a wooded lot, and a restored two-story log house. These structures are set against a backdrop of forested mountain terrain that rises to an elevation of nearly 1,000 feet.
