The residence located in McLean, Virginia, USA was designed by Robert M. Gurney Architect. It is situated on a seven acre with steeply sloping, wooded lot and bordered by a stream and parkland trail, known as Difficult Run. This residence is a project of renovation, expansion, addition and a comprehensive reorganization of the site.
In renovating the main building added a series of small additions that are implemented as needed. The roof structure is maintained, while the board and batten siding is supplanted with a combination of dry-stacked slate, stucco and limestone. Interior includes Cambrian Cream stone, dark stained oak flooring, glass, and hammered absolute black granite.
Other new additions to this house include a large library, five bedrooms and bathrooms, an exercise room, media room, laundry room, garage, guesthouse with two bedrooms, and other support spaces. These new spaces are stacked vertically to minimize the apparent size of the new structure and to adapt with the sloping topography.
