In Paris, for Paris Design Week 2026, design doesn’t simply enter the Grand Palais: for a few days it almost seems to sprout up from its very floor.

This is the idea behind Le Grand Bouquet, the installation created by Uchronia, the multidisciplinary collective founded by Julien Sebban, which from 11 to 20 September occupies the Rotonde d’Antin with a gigantic floral composition. The project starts from a seemingly simple element, the flower, to build something far more immersive. The structure follows the room’s circular geometry and picks up the floral motif already present in the mosaic, so that the large petals seem to extend the architecture rather than sit on top of it.

But Le Grand Bouquet isn’t meant only to be looked at. At the base of the installation, visitors find seating and tables that turn the space into a place to stop and stay a while. The FENIX® project draws particular attention because the material is used on the surfaces in the Giallo Evora shade, chosen to converse with the pinks and sage greens of the setting. Its matte, fingerprint-resistant surface, soft to the touch, introduces a physical dimension into the experience.

Touching thus becomes as much a part of the project as looking. The material doesn’t stay in the background as a mere technical component, but becomes directly part of how the visitor experiences the installation. Making this grand scenography possible is a network of different skills: the wrought-iron structure was created by Atelier François Pouenat, while Manufacture Prelle, Tréca Paris, Chromatic® and Seigneurie® contribute the fabrics, furnishing elements and finishes respectively.

The result is a project that works on the perception of space more than on simple decoration. The Grand Palais remains recognisable, but for a few days it is pervaded by a different atmosphere: that of an impossible garden, built on a monumental scale and capable of turning the visitor from a spectator into part of the work itself.

Le Grand Bouquet doesn’t simply add a spectacular image to a historic building, but creates an occasion to slow down, meet one another and experience matter. The installation can be visited free of charge during Paris Design Week and the Journées du Patrimoine, as part of the Grand Palais’s reopening after four years of restoration work.
