Design Studio MHNA – Marc Hertrich & Nicolas Adnet

The Paris Studio has been imagining, optimizing, and designing scenarios for over twenty years. Via the medium of interior architecture, interior decorating, and design, it offers a certain vision of elegance, a cultured, respectful, and approving look at history, but which is also curious about new technologies, arts and crafts, and culture which transcends all barriers.

Situated somewhere between analyses, a study on functionality, a laboratory for ideas, and a piece of momentary poetry, Marc Hertrich & Nicolas Adnet tell stories from around the world in homes, hotels, spas, and restaurants, and other places which they invent.

Marc Hertrich

The reason why Marc is naturally passionate about design is that craftsmanship, research and refinement are a “family affair”. Five generations of cabinet makers have led him to know how to look at, appreciate, compile and choose among the effects of materials, starting with wood varieties, their different colors, their rhythms, or the design of a cross-section.

A graduate of the famous Ecole Boulle, after having studied design at the School of Decorative Arts at the same time as cabinet making in Strasbourg, he “practiced” in two offices before joining Michel Boyer’s famous architecture agency.  Curious and creative, he was spotted and chosen to decorate the Hotel Richemond in Geneva: his first contract and “a fabulous memory which was to launch my career”. He worked there for over five years, discovering the world of luxury, “the extraordinary” then unveiled its true meaning for the young Interior Designer.

He voyaged extensively and regularly to the great capitals (for the world of fine jewelry, the opening of boutiques, fitting-out of establishments, or for the decoration of parties). 

Nicolas Adnet

Ten years after creating his agency, he decided to stop over in Paris where a memorable meeting would give new impetus to his agency’s production; a man passionate about elegance, a self-taught man who was then working for Lanvin: Nicolas Adnet, introduced by a mutual friend. Two personalities and characters, but with an eerily similar outlook and desire to embellish everyday life. Nicolas was then working in the world of haute couture, admired Montana and the work of Yves St Laurent “the absolute master who embodied elegance, respect, and impertinence, color and style”.

The two artists quickly understood the synergy which existed between them as one of life’s gifts, joined forces, and developed new projects together, imagining decoration as if writing a scenario with joy and motivation. Their cooperation marked a new departure: that of large-scale projects throughout the world.

Club Med

With Club Med, they fully participated in the move by the company into the upmarket end. They introduced the start of a new concept – that of the 5 tridents Villages and the luxury villas in Mauritius (La plantation d’Albion). Followed by numerous renovations (Cancun, Ixtapa, Bali Phuket, etc.) the gigantic project of Valmorel: its village, its 5-trident space, and its chalets. Recently another creation of the Studio MHNA has marked a new stage in the raising of the standards and the development of Club Med, that of the opening of the Village of Guilin in China.

Their work on beauty has real relevance, with a pronounced taste for attention to detail. Together, they personalize their accomplishments with the natural richness of the places which they inhabit, being inspired not only by local culture, traces, and traditions but also by the unsurpassable talent contributed by craftspeople, true partners in creation.

Thanks to this exclusive approach which forms part of a strong identity, the Studio MHNA has expanded and currently employs more than twenty-five people.

Nicolas and Marc Share Projects by Combining Their Ideas and Emotions

When the duo imagines chic places to dine, they like to work with the desire to dream and escape. Some of the restaurants designed and decorated by the studio include those of Michel Rostang (Dessirier, l’Absinthe, Jarrasse, Le Café des Abattoirs), the Pourcel brothers and Antoine Westermann, Frédéric Duca at l’Instant d’Or in Paris. These places are exuberantly associated with delectation, character to impertinence, humor to tenderness, and elegance to pleasure.

Combining functionality with poetry, creating a “multifaceted trademark which is nevertheless recognizable” in the French spirit, is the direction that the two partners are taking, bringing with them in their enthusiastic and infinite production hotel flagships such as the Martinez in Cannes or the Grand Hôtel de Cabourg, a testimonial to hundred-year-old luxury, renowned for its role at the beginning of sea bathing.


For Accor, they are helping to transform the Sofitel hotels so that they join the refined and highest end of the market in Lisbon, Marseille (Vieux Port) in Casablanca, and soon in Frankfurt. In Quiberon they have revisited the mythical thalassotherapy spa for the group, paying a fantastic tribute to Brittany…

Hotels belonging to large groups, mythical luxury hotels, high profile, and gastronomic restaurants, but also boutique hotels (Les Jardins de la Villa in Paris or the East West in Geneva), paradisiacal resorts (Moofushi in the Maldives for Constance Hotels & Resorts) and private projects, the studio produces and designs many unique works serving the history of a place but also associating artistic expression.

True creation is one that is shared and open to others, building bridges and links between the idea and the production, the design and the realization; which brings together the expertise and gives it full rein.

Certain of their works are now produced by very reputable French manufacturers.

Their 25 years of experience, their career paths, their voyages, their vision of things, their analyses, their singularity, and the fineness and richness of their ideas have brought certain of their clients to ask them to have a much larger approach toward the projects.  Today as well as being used for their expertise and savoir-faire, they have been entrusted with missions of artistic direction and global design.
