Mentha & Rosset Architectes SA

What Mentha & Rosset Architectes SA does

Mentha & Rosset Architectes SA is a privately held Swiss architecture firm headquartered in Geneva, operating since 1989 in its current corporate form and tracing its lineage to Atelier François Mentha, founded in 1965. The firm provides full-service architectural design spanning preliminary studies, project development, and construction oversight for public and private clients. Its core capabilities include urban planning, heritage building renovation, and the design of public infrastructure such as schools, administrative buildings, healthcare facilities, sports complexes, and transportation hubs.

The firm's revenue is generated through professional service fees on a project-by-project basis, with mandates sourced primarily via public architectural competitions (open and invited) and direct commissions from government bodies. Its client base is concentrated in the Canton of Geneva and Western Switzerland, with anchor relationships at Geneva Airport (Aéroport de Genève), Swiss Federal Railways (CFF), the Ville de Genève, and multiple communes including Thônex, Bellevue, Puplinge, and Corsier. Project values disclosed on the firm's portfolio range from approximately CHF 250,000 (small renovations) to over CHF 162.5 million (the Geneva Airport Baggage Handling Building), with fees structured per Swiss SIA standards. The firm is led by three partners — Olivier Favre, Eric De Meo, and Lina Piguet — supported by a team of approximately ten architects, assistants, apprentices, and administrative staff in total. Distribution is conducted exclusively through direct engagement and competition participation, with the firm's professional portfolio website (mentharosset.ch) as its primary marketing surface and no social media or paid digital channels.
