A Monopoly of Form

Miriam Frowein refreshes a rare Jacques Couëlle architecture-sculpture home near Cannes with a quiet, dialogue-driven interior that follows the building's organic logic without competing with it.

Jacques Couëlle, the French architect who coined the term architecture-sculpture and spent his career dissolving the boundary between built form and landscape, designed a small complex of six residences in the village of Castellaras, above Cannes, in the late 1950s and early 1960s. One of them has just been given a 21st-century interior refresh by Miriam Frowein — and the first thing Frowein understood, and the last thing she needed to be reminded of, was that the architecture was not the context for her work. It was the protagonist.

The house is defined by intense curves, carved volumes, flowing transitions, and an abundance of sun-drenched terraces that catch and hold the Mediterranean light at every hour. To place furniture inside it requires not a decorating sensibility but something closer to a listening one. Frowein's approach, developed in close collaboration with the owner — whom she met at the nearby Fondation Maeght in Mougins and who became a friend over the course of the project — was one of dialogue rather than intervention: a quiet interior landscape that follows the rhythm of Couëlle's vision rather than proposing an alternative to it.

A house conceived by Jacques Couëlle demands a particularly sensitive approach — his architecture is so expressive and sculptural that it naturally becomes the protagonist of any design narrative.

The kidney-shaped sofa by Pierre Augustin Rose, upholstered in bouclé, was chosen for its soft curves and their subtle echo of the architecture's fluid geometry — and for its connection to the mid-century period that produced the building. Natural oak for the dining table and chairs was selected for warmth and material continuity. Artisan-made table lamps, handcrafted elements, natural fibres — bouclé, linen, soft woven textiles — and a palette of brown, crème, and gold complete a scheme in which nothing competes and nothing is incidental.

The tiling in each room, Frowein notes, is so expressive it almost insists on remaining uncovered. The only rug is a small, organically shaped piece beneath the coffee table. A patinated bronze mural on the dining room door — abstract, layered, shifting between warmth and shadow as the light moves across it — is her favourite element in the house. It reads, she says, less as decoration than as an extension of the architecture itself.

A house of such sculptural clarity, she concludes, already provides its own guidance.

Key takeaways

• Miriam Frowein approached the interior refresh of this rare Jacques Couëlle-designed home in Castellaras as a dialogue rather than an intervention — selecting every piece, from a kidney-shaped Pierre Augustin Rose bouclé sofa to natural oak dining furniture, for its ability to echo the architecture's fluid geometry without introducing unnecessary contrast.
• Couëlle's expressive tiling, carved volumes, and abundant natural light were treated as design givens rather than surfaces to be covered or competed with — the only rug in the house is a small organic piece beneath the coffee table, and the scheme's palette of brown, crème, and gold was calibrated to recede behind the architecture's sculptural presence.
• A patinated bronze mural on the dining room door — abstract, layered, shifting in tone as the light moves across it throughout the day — is Frowein's favourite element in the house, functioning less as decoration than as integrated sculpture that embodies the home's spirit of material authenticity and expressive craft.
