Ingaïa

What Ingaïa does

Ingaïa is a French landscape architecture and urban planning studio (atelier de paysage et d'urbanisme) that delivers feasibility studies, full project management, and immersive visualization for public and private-sector clients. Its service portfolio is structured around three integrated pillars: Étude paysagère & urbaine (landscape and urban studies including master planning, PLU work, and preliminary diagnostics), Maîtrise d'œuvre et Création (full lifecycle project execution spanning preliminary design, detailed design, execution studies, construction supervision, and project acceptance under French AVP/PRO/EXE/DET/AOR phases), and Immersion et projection (3D modeling, photomontage, video, and VR headset tools used to engage citizens and stakeholders in urban renewal processes). The legal entity is TWP – SARL unipersonnelle, registered in Dogneville, and Ingaïa operates as a subsidiary of the ACERE Group.

The firm is sales-led, winning individual project contracts through a combination of portfolio reputation, regional presence, and direct client engagement. Pricing is project-based and not publicly disclosed; documented contract values range from approximately €200K (Illange zone landscaping) to €6.5M (ZAC de Lybertec development), with the bulk of revenue tied to French municipal and intercommunal clients across Grand-Est and Rhône-Alpes — including the cities of Épinal, Nancy, Strasbourg, and roughly a dozen communes. The firm operates from four offices (Épinal headquarters, Saulxures-lès-Nancy, Strasbourg, Villefranche-sur-Saône) and references work in French overseas territories. A team of approximately eight identified professionals spans landscape architects, urban planners, a light designer, a geographer, study managers, and an administrative/finance lead, with Laurent Dumas serving as Gérant (CEO equivalent). Subcontractor ties with SEBA, ADT, and ATD88 supplement delivery capacity on larger engagements.
