February 20, 2020

Esteemed designers Bruno Moinard and Claire Betaille of 4BI & Associates are passionate about design. Specialising in creating inspired interiors that will stand the test of time, here’s how they have transformed everything from museums and boutiques to hotels and luxurious private apartments.

Man of many talents

Bruno Moinard’s long and illustrious career encompasses his many talents as an architect, scenographer, designer, draftsman and painter. This multi-skilled approach means there’s always something new to be discovered. He works seamlessly across projects, from the structure of a building to the fine furnishings and bespoke artworks – giving him the opportunity to really make his mark.


Bruno began collaborating with designer Claire Betaille in 2007 and together they became 4BI & Associates in 2012. This partnership gives them the chance to bounce ideas around with someone with the same design ideals. They see every project as unique and therefore in need of unique answers.

Bruno says, “No two jobs are ever the same and that’s what makes our kind of work so captivating.”

Design philosophy

Claire explains their philosophy as, “Beauty, contemplation and the art of living interpreted differently every day.” This means they’re always on the lookout for new ways to make a difference and spark interest. She says, “We respect the context of our work, listen to what’s needed and collaborate with the finest craftsmen. We don’t like to repeat ourselves so we don’t have a signature style but people still tell us they can recognise our creative style, which is wonderful.”

Standout projects

Twenty years ago Bruno began working with Fondation Cartier and went on to create over 450 prestigious Cartier boutiques around the world. Specialising in luxury they have reimagined interiors for major luxury brands including Christie’s, Hermes, Château Latour and the Museum of Decorative Arts at the Louvre. Across all these projects they have remained true to reinterpreting places without erasing their soul, concentrating on creating surprises along the way.

Hotel Eden, Rome

The design duo is this creative genius behind all our guest rooms and suites at Hotel Eden in Rome. They also designed the lobby, meeting rooms and La Libreria. Their ideas were inspired by the hotel’s sought-after location and classic Roman influences. The result is a sophisticated, yet relaxed Italian elegance, where every detail is reminiscent of Rome. The spectacular lobby gives the sense of a grand palazzo from the moment you arrive, setting the scene for your wonderful stay.

Hôtel Plaza Athénée, Paris

Bruno reminisces that, “When we began our enduring relationship with Hotel Plaza Athénée it was the first time we had worked for a grand palace hotel.” It was their passion for respecting the history of the hotel while not letting it live in the past that won them the commission. Claire comments, “This hotel has such a glorious lobby so we worked hard to ‘wow’ guests from the moment they arrive.”

The Grill at The Dorchester

Bruno was particularly excited at the idea of redesigning The Grill at The Dorchester. He remembers, “It was challenging as several elements like the doors and ceiling are listed and there’s no natural daylight. Now though, elegant panels move to create a different light for a day-to-night feel.” He’s also a fan of the comfortable banquette seating inspired by the soft leather of a classic English car. Other modern touches include the flame-like lamps on the bar counter and the central contemporary chandelier.

Love what you do

The thing they’re most proud of is that all the projects they’ve worked on have stood the test of time. They’re influenced by trends and inspired by modernity but it’s more about longevity. “When a space improves over time, rather like a fine wine, it’s the sign of a job done well,” explains Bruno. Claire couldn’t agree more adding, ‘We really take the time to get to know a space and the surrounding area. Even if you don’t remember individual details, I like to think you’ll remember the feeling and a sense of care.”
