Designed by architect Jean-Michel Wilmotte, the Grand Palais Éphémère is a temporary building on the Champ de Mars. Its wooden structure and its ecological virtues make it a remarkable building, firmly anchored in our time. It is a true architectural feat that fits into a site whose history is, like that of the Grand Palais, intimately linked to the Universal Exhibitions of the 19th and 20th centuries.
A venue for events, the Grand Palais Éphémère is destined to host, during the restoration of the Grand Palais, the main events generally organized there, such as the FIAC, Paris Photo, the Saut Hermès or the Chanel fashion shows. The RMN - Grand Palais also offers a rich program for the public: exhibitions, live performances, and events open to all audiences mark the year. It is also an Olympic site, the Grand Palais Éphémère will host the judo and wrestling events, wheelchair rugby, and para-judo in the summer of 2024.
Located on the Joffre plateau, the Grand Palais Éphémère respects the composition of the Champ de Mars. Between the military school and the Eiffel Tower, it rises to a height of 20 meters, without overlooking the military school, which dominates it 16 meters higher. Integrated into the building, the statue of Marshal Joffre took advantage of this installation to be completely restored. The 44 monumental arches of the Grand Palais Ephémère were assembled on-site in just three months.
The building's structure is designed to be modular and can be reused in various configurations after the de-installation of the Champ-de-Mars in autumn 2024. The modularity, the use of sustainable materials, and the structure of the Grand Palais Ephémère make it a project fully in line with the environmental imperatives of our time.
The wood used for the structure is PEFC-labelled, i.e. from a sustainably managed forest. Wood is a carbon sink: the CO2 captured by the paint is estimated at 1956 tonnes! The double skin surrounding the building has strong acoustic, thermal, and ventilation properties, which reduces energy consumption. The transparent canvas visible from the outside is made of mineral and non-oily polymer (ETFE), generating 90% less energy in manufacturing compared to glass; it is fully recyclable.
