On the occasion of Paris Design Week 2025, theSully Hotel becomes the stage for two complementary worlds. In its salons, Foil de Lucas Huillet et Alexandre Isaïe Helwani It immerses the visitor in a unique sensory experience where design becomes story and fragrance. While in the orangery and gardens, the house YMER&MALTA, founded by Valérie Maltaverne, presents a selection of exceptional art furniture, the result of a refined dialogue between innovation and French craftsmanship. Two exhibitions, two approaches, but the same aim: to remind us that design is a total experience, capable of uniting the senses, memory and matter.
Madness: when the object breathes
With Foil, Lucas Huillet, designer and ceramicist, partners with the perfumer and historian Alexandre Helwani to create a hybrid work, somewhere between sculpture and fragrance. Here, ceramics become writing, a sensitive line traced in space, while the scents of incense, myrrh, or cedar envelop the viewer in an olfactory memory. More than an object, Foil is an immersion: matter engages in dialogue with the invisible, and perfume becomes architecture.
The title itself resonates like a manifesto. "Follies" were once those pleasure pavilions where one could lose oneself in reverie. The one imagined by Huillet and Helwani is contemporary, radical, and poetic. It offers an intimate journey where the object is no longer merely seen but breathed in, experienced, inhabited.

YMER&MALTA : sculpted nature
Still at the Hôtel de Sully, but on the orangery and garden side, YMER&MALTA offers a different perspective. Founded by Valérie Maltaverne, the publishing house has become a benchmark of "slow made," situating its creations within a long timeframe, combining rigorous material selection with artisanal virtuosity.
For Paris Design Week, she presents a selection of pieces where nature inspires the forms and materials. A bird-shaped bench transforms into a graphic silhouette, another evokes the branches of an oak tree with its sculpted limbs, while light fixtures rest like soothing pebbles. Among the featured designers is the duo Normal Studio reveals Illusions, a wood and steel ensemble that plays on the contrasts between density and transparency.
Two voices, one ambition
Although the worlds seem far apart — here perfume and ceramics, there furniture and nature — they nevertheless share a common ambition: to give design a broader, more sensitive and sustainable dimension. Foil It creates a dialogue between the immaterial and the material, while YMER&MALTA reinvents furniture as living sculpture. In both cases, the same requirement applies: a slow, rigorous creation, imbued with meaning and memory.

The elegant setting of the Hôtel de Sully and the echo of the Marais
The choice ofSully Hotel This is not insignificant. An iconic monument of Parisian heritage, it provides an ideal setting for these initiatives that connect past and present, tradition and innovation. The salons, the orangery, and the gardens thus become chapters in a larger narrative, showcasing the many facets of contemporary creation.
In parallel, the Joseph Gallery, partner of Paris Design Week In the Marais district, this dialogue continues by welcoming other emerging and established talents. Together, these venues weave a sensitive map of the event: from the Hôtel de Sully to the Marais, a single spirit flows through Paris and affirms the vitality of contemporary design.
A sensory journey
All Sully Hotel, Paris Design Week it does not simply show objects: it offers experiences. Foil YMER&MALTA invites you to lose yourself in an invisible architecture made of materials and scents. It invites you to sit, dream, and contemplate forms inspired by nature. Two invitations to slow down, to feel, to rediscover the power of the creative gesture.
By bringing together these contrasting yet complementary worlds, Paris Design Week reminds us that design is not just about forms, but also about emotions, stories, and breath. Between madness and poetry, between garden and living room, theSully Hotel becomes the beating heart of a French creation that dares to be excellent and unexpected.
