Extension for World Trade Organization (WTO)

Geneva, Switzerland, 2012

The extension building of the historic World Trade Organization (WTO) headquarters is located on the shores of Lac Léman in Geneva. The 9-storey administration building for the World Trade Organization accommodates offices, a library, a restaurant, printing and technical facilities and an underground car park. The crystalline building is split in two areas: offices on the upper floors and infrastructure on the lower floors. The library is located on the mezzanine floor that is characterized by a set-back plinth thus creating a floating caracter. Given the short distance to the main building and for environmental reasons, the building was designed with a double-shell diaphragm wall. The ground floors in split-level system allow an efficient traffic routing on the parking floors.
