Located on the Joffre plateau, the Grand Palais Éphémère respects the layout of the Champ de Mars. Positioned between the École Militaire and the Eiffel Tower, it rises to a height of 20 metres, without exceeding the height of the École Militaire, which stands 16 metres higher. Integrated into the building, the statue of Marshal Joffre was fully restored as part of the installation. The 44 monumental arches of the Grand Palais Éphémère were assembled on site in just three months.
The structure of the building is designed to be modular and can be reused in various configurations after its dismantling from the Champ de Mars in autumn 2024. Its modularity, the use of sustainable materials, and the structure itself make the Grand Palais Éphémère a project fully aligned with today’s environmental imperatives.
The wood used for the structure is PEFC-certified, meaning it comes from sustainably managed forests. Wood acts as a carbon sink: the CO2 captured by the structure is estimated at 1,956 tonnes! The double skin surrounding the building provides strong acoustic, thermal, and ventilation benefits, helping to reduce energy consumption. The transparent membrane visible from the outside is made from a non-oil-based mineral polymer (ETFE), which requires 90% less energy to produce than glass and is fully recyclable.
