In 2006, Laurent de Wurstemberger founded the Atelier ar-ter in Carouge with two partners. In 2011, along with material scientist Rodrigo Fernandez, he established the company Terrabloc, which transforms excavated material from construction sites into compacted clay blocks. In 2018, he opened his architectural practice in Geneva and has since completed several smaller, more sophisticated projects, including the renovation of a farm in Choully (GE).
