Agence d’Architecture Willerval et Associés

What Agence d’Architecture Willerval et Associés does

Agence d'Architecture Willerval et Associés is a privately held French architecture firm headquartered in Clamart (Île-de-France). Originally founded in 1994 by Bruno Willerval as Agence d'Architecture Bruno Willerval, the practice was reorganized in 2019 under its current name when Pierre-Alexandre Lavaut and Natalie Schoettler — both long-tenured architects within the agency — were admitted as co-gérant partners alongside the founder. The firm operates across the full spectrum of building typologies, organized internally into Tertiaire (commercial/offices), Industrie (industrial and infrastructure), Réhabilitation (renovation and adaptive reuse), Logements (multi-family housing), Maisons Privées (private residences), and Hôtels (hospitality), delivering full-service architectural missions from conception and design development through to construction supervision (maîtrise d'œuvre).

Revenue is generated through project-based professional service fees charged on a quote-driven basis, with mission scopes ranging from conception-only through to full maîtrise d'œuvre. The firm serves a client base spanning large enterprises (Allianz France, Microsoft Europe via EOS Generali, EDF, Orange, Crédit du Maroc, Mazars, Generali, OTV/Veolia, CGG Véritas, Ville de Longjumeau), real estate developers (EIFFAGE Immobilier, Bouygues Immobilier, Cogedim, Nexity Entreprises, Foncier Promoteur Immobilier, Nexity Fereal, Les Nouveaux Constructeurs), and specialized hospitality operators (Wome Partner, IRRAPRI). Go-to-market is direct engagement combined with participation in architectural competitions, as evidenced by the international competition win for the EOS Generali/Microsoft Europe headquarters. Distribution is regional, primarily Île-de-France, with selective international projects in Casablanca (Morocco) and Guadeloupe, and outposts tied to specific commissions in Clermont-Ferrand, Flamanville, and Giffaumont-Champaubert.

The firm's core technical differentiation sits in sustainable architecture: deep expertise in biosourced materials, carbon-footprint reduction, biodiversity integration, modular construction, and building reuse, with demonstrated delivery against HQE, BREEAM, LEED, BBC, BBC A, BBC Effinergie Rénovation, and WIREDSCORE certifications. Marquee projects include Tour Prisma (27,735 m²), Tour Exaltis with Arquitectonica (23,000 m²), Tour Athéna/Allianz One (42,000 m²), EOS Generali/Microsoft Europe with Ratti (46,270 m²), Eco Campus Orange (71,600 m²), Flamanville EPR nuclear support buildings (133,900 m²), Les Arènes Casablanca (12,800 m²), and ongoing multi-residential and hospitality operations. The firm maintains an associated-architect partnership model for projects exceeding in-house scale, collaborating with firms including Carlo Ratti Associati, Arquitectonica, Omar Alaoui Architectes, BEGARIN et WEYGAND, Alain Combes, and Partenaires Architectes.
