Casper Mueller Kneer Build a Perfume Fountain at the Heart of Caron’s New Paris Store.

Runway sets are the most short-lived architecture there is. A few minutes of drama, then the trucks arrive. Casper Mueller Kneer Architects know the format better than most, having designed shows for Saint Laurent, Loewe and Celiné. What makes the London and Berlin practice special is that their creative verve survives the move into permanent rooms. We saw it at Self-Portrait’s Mayfair flagship, wrapped head to toe in dark Cornish mineral clay. Their new Caron store at 332 Rue Saint-Honoré in Paris pushes it further.

Founded in 1904 and billed as Paris’ oldest perfume house, Caron briefed the architects through the artistic vision of its director, Olivia de Rothschild. The references are layered—house heritage, the Art Deco era and Caron’s long relationship with artistic glass—yet the brief was refreshingly blunt: a space for smelling, with nothing to distract.

Every element of the Mayfair flagship was custom made, aligning with the sense of originality the fashion brand is known for.

The shopfront plays it cool, with a small vitrine of dioramas beside the entrance. The real hook is visible from the street: a glowing column of colour at the centre of the store.

Inside, everything pulls upward. Walls and columns step in and out in true Art Deco fashion, with display folded into the articulation. Stainless steel lines the space, and lighting is built directly into the walls as one continuous band of illumination.

The steel has been treated to reflect without forming clear images, so the ‘coloured juices’ (perfume-industry shorthand for the liquid fragrance inside the bottle) staggered up the walls appear as soft, hazy smudges across every surface. Mirrors carry the room on and on, and the monochrome shell only comes alive through the perfume and light.

That restraint is pure set-design thinking—build the stage, then let the product perform.

And then there’s the fountain. Refilling bottles is part of Caron’s signature service, and here the ritual gets a full-height centrepiece. Bundles of hand-frosted, fluted glass tubes are arranged in a circle, back-lit and filled with Caron’s perfumes. Engineered and fabricated by Atelier Blam, it draws on Art Deco chandeliers and the house’s artisanal glassmaking. It’s a light, display and service point in one, and we can’t think of another fragrance store that has attempted anything like it.

The fountain anchors a three-zone plan, with the Collection Merveilleuse and Pour un Homme to the front and back, cash desks and archive walls at the rear, and a stair up to a first-floor VIP space.

Plenty of architects can design a beautiful shop. Very few can make one feel like the first seconds of a show, every day of the week. Casper Mueller Kneer just did it with perfume.
