What Les Marsiens does
Les Marsiens is a Marseille-based collective of designers and architects operating as SAS Les Marsiens since 2016, specializing in the conception and fabrication of furniture, micro-architecture, and pedagogical scenographic installations for common spaces. The firm delivers three integrated service lines — Concertation (immersive user consultation via workshops, surveys, and usage testing), Conception (design from sketch to execution plans), and Réalisation (in-house production in their workshop at Le Couvent, La Belle de Mai) — and emphasizes participatory co-construction with end users, durable materials (wood, powder-coated aluminum, recycled plastic), and material reuse across projects.
The business model is project-based and quote-based: clients engage through the website, public procurement (marché public), or referral, with proposals priced per project scope. Revenue is generated as one-time project fees rather than recurring licensing. The client base spans public sector (Ville de Marseille, Parc National des Ecrins, Parc National de la Vanoise, SA3M de Montpellier, DDTM), cultural institutions (Mucem, Muséum National d'Histoire Naturelle, Théâtre de la Criée, FRAC PACA), educational establishments (ECV Aix, Beaux-Arts de Marseille), and selective enterprise (Décathlon Btwin Village). The core team of four (2 designers, 2 architects including a cabinetmaker) is repeatedly augmented by a network of design-collective partners (Jaune Sardine, Oz Le Design, Nuud Studio, Prémices & Co, Atelier Coco) and specialist suppliers (Soboma, AFM13, Petzl).
Geographically, Les Marsiens is headquartered in Marseille (siège social at 69 Traverse Tiboulen; workshop at 52 Rue Levat) and operates across France, with documented projects in Provence-Alpes-Côte d'Azur, Hauts-de-France (Lille), Occitanie (Montpellier/Lattes), Auvergne-Rhône-Alpes (Ecrins, Baronnies), and Pays de la Loire (Nantes). The firm is founder-controlled (Vince Musy as President, Livia Ripamonti and Margot Fressard as Directrices Générales), with no external investment, no subsidiaries, and a €6,000 registered capital.
