Kms Architectes

What Kms Architectes does

KMS architectes SA is a Swiss architecture firm (Société Anonyme) headquartered in Geneva that delivers full-service architectural work following the SIA 102 standard, from feasibility studies and project development through tendering and construction management. Founded in 1964 by Arthur Lozeron, Marc Mozer, and René Koechlin, the firm has evolved through successive partnership names (Atelier KM, Bureau KMMS, Atelier KMS) into its current form, with Patrick Corbat and Christian Carénou as associate administrators following Philippe Pochelon's January 2025 retirement after 45 years. The practice operates today with approximately six professionals (two associates plus three collaborators plus an administrative collaborator), a material compression from a historical headcount range of 15–45 collaborators, and is based at avenue d'Aïre 7 in the Charmilles district.

The firm specializes in residential development (individual villas, PPE condominiums, HBM/HM social housing, housing cooperatives), public-sector commissions (communal buildings, schools, restaurants), commercial and hotel projects (notably a 141-room aparthotel at Cointrin), and renovation/energy retrofit work, with documented expertise in mixed wood-concrete construction and low-energy design. Project scale ranges from individual villas to a 214-unit complex at La Florence (Les Acacias) and a 120-bed nursing home competition. The technology base is conventional architectural practice with no disclosed proprietary software, API, or AI tooling.

Revenue is generated through professional-services fees structured along SIA percentage-based or hourly billing on multi-year engagements, sourced primarily through direct enterprise sales, public tenders requiring MPQ qualification, and architectural competitions. Geographic focus is the Canton of Geneva with limited extension into Vaud and Valais. Distribution channels are direct client engagement plus competition entries; the firm avoids external institutional capital and remains owner-operated. Customer concentration spans private developers (Promau SA, Realimmo SA, EDFEN Immobilier SA, Solvalor 61), public communes (Perly-Certoux, Russin), foundations (Alphonse Carfagni), and industrial clients (Boccard Parcs et Jardins SA), indicating a diversified book across segments.
