Dominus' winery is the first project realized in the United States by the design architects, Jacques Herzog and Pierre de Meuron. Based in Basel, Switzerland, they are well-known for their numerous European projects, including in London the Tate Gallery's new Bankside facilities. The architects were also amongst the three finalists for the Museum of Modern Art's new museum in New York.
1997 is the first vintage of Dominus to be produced at its own winery. Its previous thirteen vintages were crushed and aged at a nearby facility. Set back in the vineyard, the dark green basalt rock building integrates into the landscape. It is a linear construction 140 meters (462 feet) long, 25 meters (82 feet) wide and 8 meters (27 feet high). The exterior is composed of walls of gabions, which are essentially galvanized baskets containing stones. Commonly round retaining river banks or earthwalls, this application as a building’s exterior facade is unique and provides protection from the scorching heat by day and the cold at night. The baskets have no 'mortar' and the spaces between the rocks act as a 'filigree,' allowing the passage of natural light into the rooms during the day and artificial light to radiate out at night.
