A monumental bouquet of flowers blooms at the Grand Palais for Paris Design Week 2026.

Design is blooming all over Paris during Paris Design Week, from September 10 to 19, 2026. At the Grand Palais, Uchronia sets the scene with Le Grand Bouquet, an oversized flower to discover from September 11 to 20, 2026.

Designers, architects, decorators and emerging talents take over the capital for Paris Design Week, September 10–19, 2026. Launched in 2011 by Maison&Objet, the event moves design out of the showrooms and into roughly 400 Paris addresses. Galleries, shops, cultural institutions and heritage sites become the backdrop for exhibitions, installations, open doors, workshops, tours, meet‑ups and round tables. Furniture, interior architecture, decorative arts or graphic design: disciplines cross paths across the city’s districts, following in the footsteps of Maison&Objet Paris, with new names, expertise and trends to watch.

Paris Design Week 2026 returns in September: dates, venues and the lineup of free installations.

This year, creativity reaches the Grand Palais. Uchronia brings to life Le Grand Bouquet, a monumental and free installation to be discovered in the Rotonde du Palais d’Antin, from September 11 to 20, 2026 (closed on Mondays). A giant flower unfurls its petals as a celebration of joy, color, and imagination, with a clear guiding principle: to make the artwork converse with the surroundings that frame it.

To give it shape, Uchronia draws directly on the Rotonde’s details. The floral motif of the floor mosaic, the vegetal mouldings and the venue’s circular lines shape the silhouette of The Grand Bouquet, which translates these elements on a large scale into a contemporary, oversized interpretation.

The installation spills out onto the forecourt, welcoming visitors as a threshold between the real and the imagined. The project even branches out into the Grand Palais's Design and Decorative Arts Shop, with a curated selection of objects, furniture and accessories drawn from the architecture studio’s world.

Uchronia is no stranger to Paris Design Week. The studio founded by Julien Sebban had already taken over the Cour d'honneur of the Hôtel de la Marine in 2024 with Day Bed, an XXL canopy bed perched on a ceramic platform.

After putting design to bed, Uchronia lets it bloom: a new backdrop at the Grand Palais, but the same playful conversation with the building’s architecture, now amplified by a profusion of petals.
