After having graduated from the renowned École Nationale Supérieure des Arts Décoratifs (ENSAD), Paris, in 1999, Guillaume Bardet started his career as a designer during his residency at the Villa Medicis in Rome.
There, he received a grant from the French Academy in Rome which allowed him to realize his first major project: “Mobilier Immobile”, composed of nine very large pieces in marble.
While continuing to design furniture, he began to work in the field of interior architecture and urban planning, acquiring experience that he would later pass on as a professor at the École Nationale Supérieure de Création Industrielle (ENSCI), in Paris, beginning in 2005.

Bardet is a man of great projects.
After “Mobilier Immobile » at the Villa Medicis, Bardet embarked on his ambitious project “l’Usage des jours”: for a year, Bardet drew an object per day, and as an extension of this experience, he ensured its realization, the following year, with a dozen potters.
365 ceramic objects were thus created.
The adventure “L’Usage des jours” was praised by the Bettencourt Foundation in October 2011: Bardet received the Prize of the intelligence of the hand for his creative work.
This project has traveled throughout Europe: to Sèvres – Cité de la céramique in Sèvres, France, to the Grand-Hornu in Belgium, to the Château des Adhémar – Centre d’art contemporain in Montélimar, France, and to the Museum of Design and Contemporary Applied Arts (Mudac) in Lausanne, Switzerland.

In 2013, he began teaching at the National School of Decorative Arts (EnsAD) in Paris, and became a frequent collaborator at Hermès, designing a collection of objects for their Home Fragrance line, and becoming the Educational Director for their Foundation in 2015.
Since autumn 2015, Bardet has devoted himself fully to his project « La fabrique du présent », the first chapter of which was shown in autumn 2017 at Le Corbusier’s iconic building near Lyon, Le Couvent de la Tourette.
In April 2019, Bardet embarked on his first collaboration with Galerie kreo. The exhibition displayed a collection of pieces made entirely of bronze: a very long oblong table with uneven feet and a smooth table top, a large pendant light, a free-shaped coffee table, a slender bench, and a series of anthropomorphic stools.

In 2023, as part of the restoration of Notre-Dame, the Archbishop of Paris, Monsignor Ulrich, announced the selection of Guillaume Bardet for the creation of the cathedral’s liturgical furniture. Bardet was tasked with designing five key elements: the altar, the cathedra and its associated seats, the ambo, the tabernacle, and the baptistery. The introduction of bronze into this iconic building, primarily composed of stone and stained glass, allows for the harmonious integration of these pieces within the sacred and majestic setting of Notre-Dame.
