The gardens of this Georgetown residence serve as relaxation space for the owners, as entertainment space for their guests, and as an open-air museum to display their large collection of outdoor sculpture. The garden is divided into three rooms. On the west are a swimming pool and its associated terraces. When unoccupied, the pool serves as a reflecting pool. The paving of the terraces has been set in turf to help blur the distinction between hardscape and landscape. In the center is a garden courtyard, enclosed by high walls, that is the main outdoor entertaining space. Tall gateways lead to the pool terrace and the sculpture garden. The sculpture garden, on the east side, is a grid of columnar trees placed in gravel that host a revolving exhibition of the owners’ larger pieces.
