What Archigroup does

Archigroup (legally GRAND AIR) is a privately held French architecture, engineering, and construction-realization group founded in 1973 and headquartered in Limonest (Lyon metropolitan area). It operates through five wholly-owned subsidiaries: Archigroup Design and Archigroup Grand Sud (architectural conception across residential, commercial, industrial, and public buildings), Archigroup Réalisation (general contracting and project execution), Ingegroup Ingénierie (construction economics plus fluid/thermal engineering using BIM/3D, created in 2004 with 12 agencies across southeast France), and Inspire Environnement (environmental consulting covering RE 2020 compliance, lifecycle analysis, carbon impact studies, and certifications including HQE, BREEAM, Effinergie, BBCA, NF Habitat HQE, Osmoz/Well, and WiredScore/R2S).

The group's commercial proposition centers on "Ré-Architecture," a proprietary concept that reframes building renovation beyond rehabilitation to create new programmatic value while preserving embodied energy, and on integrated multidisciplinary delivery spanning conception, engineering economics, environmental certification support, and construction realization. Revenue is generated through project-based professional fees from competitive tenders and direct commissions rather than product or subscription pricing; named enterprise clients include Crédit Agricole (Centre-Est and des Savoie), Michelin, Renault Trucks / Volvo Group, RTE, ARQUUS (Volvo Group), Groupe Liebot (K-Line), Malakoff Médéric, SOGERIM, and Loire Habitat, with social housing providers as a recurring public-sector segment. Multi-year project values disclosed in the portfolio range from roughly 6.5 M€ to 104 M€ in construction value.

Geographically the group is concentrated in southeast France through offices in Limonest (HQ), Saint-Jean-de-Védas (Montpellier), and Méry (Chambéry), and it pursues projects nationally via direct enterprise engagement, architecture competitions, and co-design partnerships (e.g., with BDP on Y-Spot Partners in Grenoble). The firm has no external investment or public listing; ownership and direction are anchored by President Directeur Général Denys Léger.
