Puces Portrait: Margaux Lemmet

Less concerned with big names than beautiful objects, new dealer Margaux Lemmet mixes Art Deco, anonymous finds and contemporary art with an instinctive eye for interiors.

Founded by Margaux Lemmet in 2025, Galerie L’Oustau arrived at the Marché Paul Bert Serpette in spring 2026. Her beautifully curated stand brings together furniture and decorative arts from the early twentieth century to the 1960s, with a particular passion for Art Deco. The selection mixes recognized names with lesser-known designers and anonymous works, chosen for their quality, materials and presence rather than their signatures alone. Lemmet also incorporates contemporary art into the mix, drawn to artists whose work explores the expressive qualities of materials. Rather than simply displaying objects, she creates carefully composed interiors, bringing different eras and styles into dialogue. In the conversation that follows, she talks about the thrill of the find, how objects carry stories, and her favourite French artists and designers.
