Antoine Barc (Partner Director Lausanne)

Born in 1981 in Vannes (FR), Antoine Barc grew up along the Atlantic coast of Brittany. He forged a deep connection to the value of landscape and, by association, to the link between architecture and territory.

During his studies at the École Polytechnique Fédérale de Lausanne (EPFL), he was awarded the prize for the best project in the urban mobility laboratory in 2004. He obtained his degree in architecture in 2005, for a project dealing with the link between architecture, landscape, and maritime infrastructure.

After professional experiences in Paris and Geneva, Antoine Barc joined RDR in 2006. He is responsible for projects such as the headquarters of the Bobst Group in Mex, the La Mouline underpass in Chavannes-près-Renens, the housing for the Crédit Agricole Indosuez pension fund in Lausanne, and the student housing Les Triaudes in Ecublens. He and his team won competitions such as Rhône 8 and Place Bel Air 1 in Geneva, and the Les Jordils neighborhood in St Sulpice, and En Cojonnex in Chalet-à Gobet.

Appointed deputy director in 2013, Antoine Barc has been a partner since 2018. With Santiago Pagés, he leads a team invested in housing projects, heritage transformations, and mixed-use neighborhoods.

His interest in the notion of team, and the importance he attaches to human values, lead him to also take on the mission of partner in charge of Human Resources.
