An architect and urban planner, with degrees from the Ecole d'Architecture de Paris La Seine, the École des Hautes Etudes en Sciences Sociales (EHESS) and Sciences Po Paris. He is Professor at the Ecole Nationale Supérieure d'Architecture de Versailles (ENSAV). With Caroline Poulin and François Decoster, Djamel Klouche co-founded l'AUC, an architecture and urban planning firm based in Paris, joined by Alessandro Gess as a partner.
l'AUC was awarded the “Grand Prix National de l'Urbanisme” by the French Minister of Housing on December 15, 2021, for its body of work. In September 2023, l’AUC received the UIA's Albert Abercrombie Prize for Urban Planning and Design.
l'AUC is very much involved in the process of transforming existing buildings, particularly those of modern heritage: l’AUC has just delivered a project to transform two single-function office towers into a mixed-use program combining offices, housing, hotel and services open to the city, on behalf of Beffimo in Brussels' Gare du Nord district, and is currently working on the transformation of the Tour des Poissonniers in Paris.
