Exterior forms are emphasized with glass and fiber-cement panels at the top level, soaring over and sheltering containers clad in tougher, leathery Corten Steel at the ground level. Exposed concrete walls and rock-filled gabion retaining was selected to anchor the partially day-lighted basement level and garages to the land. Materials were chosen to be low-maintenance, relatively inexpensive, and to contrast the volumes that express the interior spaces.
