In the heart of Paris’s Saint-Germain district, where artistic and literary movements have thrived for centuries, Tonnemani Project by MERSI Architecture has brought new life to a historic 110 square meter space. Originally a sculptor’s studio, the residence carried the imprint of its former occupant, an artist who worked there for many years until his final days. When Meryl Motyka and Simon Mimoun, co-founders of MERSI, first stepped inside, they were struck by its distinct atmosphere.
“We were immediately fascinated by the energy of the space,” says Mimoun. “The challenge was to respect its artistic past while adapting it for contemporary living.”
Bringing Light into the Space
One of the studio’s greatest challenges was its lack of natural light. MERSI sought to create an airy, open environment by replacing the original Parisian canopy with an operable glass roof. This structural change introduced abundant daylight into the space and allowed the outdoors to connect with the interiors. A redesigned reception area became the heart of the home, with a central island that serves as both a kitchen and a social hub. A mirrored table enhances the sense of space by reflecting sunlight throughout the room.
This transformation turned the former atelier into a place where the owners can host dinners under the Parisian sky, regardless of the weather, and enjoy summer evenings on their terrace with an uninterrupted connection to the outdoors.
A Thoughtful Approach to Layout and Functionality
Beyond maximizing light, MERSI completely restructured the space to improve flow and functionality. The apartment was opened up, allowing for better movement while integrating custom-made furnishings that either reveal or discreetly conceal features like a hidden bar and TV unit.
In the bedroom area, a rounded TV console extends into a bench, creating a fluid transition between the entertainment space and seating. The master suite features a striking alabaster-lit vanity, while bespoke dressing rooms were designed to improve the sense of privacy and luxury in both bedroom suites.
Craftsmanship and Artistic Identity
Throughout the renovation, MERSI collaborated with artisans and artists to define the apartment’s distinct identity. A decorative patina finish in the kitchen creates a subtle, cloud-like effect, while a panoramic jute fabric wall-covering depicting the Viñales Valley serves as a striking focal point. In another nod to organic design, a living green wall composed of stabilized hydroponic plants breathes life into the space.
Beyond textures and finishes, carefully curated objects reinforce the residence’s personality. A suspended alabaster pendant light casts a warm glow over the living area, while an array of ceramics fills delicately integrated wall niches. One of the most eye-catching additions is a monumental dried wood totem, discovered at a flea market in Lille, which now stands as a centerpiece of the living space.
A Minimalist Vision with Hidden Functionality
MERSI designed the apartment to be fully equipped while maintaining a pared-down aesthetic, free from unnecessary embellishments. Every functional element, from the home theater to the bar, remains discreetly hidden, allowing the architectural design to take precedence. Even the air conditioning and the operable glass roof seamlessly integrate into the structure, ensuring a balance between comfort and aesthetics.
Reflecting on the year-long project, Meryl Motyka shares, “We played with textures, materials, and craft techniques to create an interior that feels both effortless and refined. This was a complex renovation, but the result is exactly what we envisioned.”
