What TANDEM ARCHITECTES does

TANDEM ARCHITECTES is a multidisciplinary architecture and design agency founded in 2000 and headquartered at 29 bis Cours Jean Jaurès in Grenoble, France. The firm operates across architectural conception, interior architecture and space design, urban planning, project programming, quantity surveying, construction supervision (OPC), and rehabilitation, with documented expertise in sustainable building standards including HQE (Haute Qualité Environnementale), BBC (Bâtiment Basse Consommation), and HQU (Haute Qualité d'Usage). It applies BIM-based construction documentation and participatory design methods that involve end-users in the design process, led by managing partner Franck Pernet (Architect ENSAIS) and associate Astrid Girard (Operations Manager and interior designer), supported by a small team including a HMONP architect, a BIM/CAD draftsperson, and a civil engineering graduate.

The firm serves public-sector clients (municipal schools, healthcare centers, fire stations, university restaurants), social housing providers (Pluralis, Cefimmo), and private commercial customers (retail, tourism residences, agriculture) across the Auvergne-Rhône-Alpes region and adjacent departments. Go-to-market is sales-led, driven by competitive architectural tenders (concours) for public projects and direct referrals within a regional professional network. Revenue is generated through custom project-based professional services fees, with multi-year contract cadences tied to construction phases, and the firm maintains an Instagram presence plus a portfolio website as marketing channels.

TANDEM has accumulated more than 20 documented projects, including a 2012 Prix Spécial du Jury Crea Bois award for the Canopée BBC office, and operates without external investors, parent companies, or subsidiaries. Its competitive positioning rests on integrated multidisciplinary delivery, niche mountain-architecture expertise, and a track record in sustainable public-sector construction rather than scale or technology differentiation.
