Ilex paysage+urbanisme

What Ilex paysage+urbanisme does

Ilex paysage+urbanisme is a Lyon-headquartered landscape architecture and urban planning firm founded in 1987 (operational since approximately 1989) that delivers integrated design services to public-sector clients across France and Switzerland. The firm operates through competitive public procurement, typically serving as lead designer (mandataire) within multidisciplinary consortia of engineering, hydrology, mobility, and ecological partners on metropolitan regeneration, public-space reconquest, urban parks, mobility infrastructure (tramways, BRT, station hubs), and territorial foresight studies. Documented client authorities include Métropole de Lyon, Euroméditerranée, Société du Grand Paris, Grand Paris Aménagement, Villes de Neuilly-sur-Seine, Marseille, Villeurbanne, Angers, Avignon, Fribourg, and Canton de Genève, with project works budgets ranging from €2M to €110M+.

The firm's technical differentiation rests on an integrated practice combining landscape architecture, urban planning, light landscape design, and applied ecological engineering. Core proprietary capabilities include in-situ soil refertilization of inert urban substrates (demonstrated at Jardins du Pré Gaudry, 11,000 m²) and an ectomycorrhizal fungi rehabilitation methodology developed through a CIFRE doctoral partnership with CNRS UMR CEFE Montpellier, published in 2023. A college-of-eight senior leadership structure governs approximately 30 in-house designers and an administrative team, with the firm having transitioned from founder Guerric Péré to Nadia Herbreteau (Présidente) and Isabelle Vignolles (Directrice Générale) in 2023.

Revenue is generated through project-based, multi-year design contracts awarded via appels d'offres and direct commissions; pricing is not publicly disclosed. Revenue concentration is structurally total in the public sector, with recurring multi-project relationships with a handful of metropolitan and national authorities. The firm's reputation is anchored by a portfolio of 30+ documented projects and a sustained record of national and European awards (Victoires du Paysage, MIPIM, LILA, Équerre d'Argent, Green Cities Award Europe, BATIRVERT) over the past decade.
