What Cos Workshop does

Cos Workshop (operating as Atelier COS) is a Paris-based architecture, design, and consulting firm founded in 2001 by Didier Beautemps. The studio specializes in architecture and interior design for shops, restaurants, and office buildings, operating as a cohesive design practice rather than a productized service. Its offering is structured around three pillars visible on the website: Projets (project delivery), Atelier (studio practice/consulting), and Éditions (editorial publications), which together suggest a brand extending beyond pure project execution into thought leadership and brand-building.

The firm employs 51-100 people and operates from a single Paris location, with a bilingual French/English website indicating some capacity to serve international clients. Named project references visible on the site (including the Cheval Blanc property) suggest a portfolio focused on premium retail and hospitality clients. The firm does not disclose proprietary technology, and there is no indication of platform, SaaS, or technology-enabled service components.

The business model is project-based professional services — fees are generated through design commissions and consulting engagements, with pricing not publicly disclosed. Customer acquisition is driven primarily through direct engagement (website contact, in-person consultations) and the firm's portfolio/reputation. No acquisition history, funding rounds, or institutional ownership is disclosed, and the company appears to operate as an independent, founder-led studio.
