What La/ba Architectes does

LA/BA Architectes is a French multidisciplinary architecture, urbanism, and landscape design firm founded in Paris in 2017–2018 by Maud Leforestier and Frédéric Blerot. It is organized as a Société par Actions Simplifiée (SAS) with €50,000 share capital and operates under the multi-pole Groupe LA/BA umbrella, which comprises four autonomous practice areas: Pôle Architecture (construction and rehabilitation), Pôle Territoires (urbanism and mobility), Studio Eden (environmental and industrial infrastructure including water, energy, and waste), and Signes Paysages (landscape architecture). The firm maintains additional offices in Lyon (led by Associate Nils Degremont) and Geneva (LA/BA SUD EST).

The firm's core offering is the integrated design of complex mobility and public-space infrastructure—tramways, BHNS (high-quality bus networks), multimodal hubs, maintenance and stabling centers (CMRs), and parking structures—for French public-sector clients (SNCF, ADP, metropolitan authorities such as Brest Métropole and GPSEO, multiple CHU hospitals, parking operators EFFIA and Interparking) and a smaller set of private developers (notably repeat client CITANIUM). Underlying technology centers on Building Information Modeling (BIM) applied specifically to public-space projects, iterative agile multidisciplinary design methods, and cross-disciplinary teams combining architects, urbanists, and landscape designers; the firm cites over 100 completed operations across France and abroad.

Revenue is generated exclusively through professional-services fees billed on public procurement contracts and direct private mandates, with contract construction values ranging from approximately €569K (Évian ferry quay) to €115M (CDG Airport parking by ADP) and architecture fees negotiated per project under frameworks including maîtrise d'œuvre complète, conception-réalisation, and marché global de performance. Go-to-market is sales-led: a dedicated development director (Maria Aramendia) and a responsible des appels d'offres (Amandine Ceccaldi) drive competitive-bid wins through public procurement and consortium partnerships with engineering firms (Egis, Systra, Artelia, Ingérop) and general contractors (Eiffage, Léon Grosse, Fayat). The firm supplements this with directly commissioned private work (CITANIUM commercial buildings, BRS Barry Rogliano Salles office renovation in Geneva) and pursues international mandates via multinational consortia (Aarhus tramway in Denmark, Al-Ula tram-train in Saudi Arabia).

Broad incumbents

• Architecture-Studio: Larger Paris-based architecture firm with international practice spanning mobility, urbanism, and public buildings. Competes with LA/BA in concours for major public infrastructure but operates at significantly greater scale and broader portfolio.
• BIG (Bjarke Ingels Group): Internationally active architecture firm with transport-oriented work (metros, mobility hubs, urban masterplans). Competes for high-visibility international concours where LA/BA is also pursuing consortium-led mandates.
• Foster + Partners: Global architecture incumbent with significant transport and infrastructure work (airports, metro stations, urban masterplans). Competes in international concours and on flagship public mandates where LA/BA also bids.
• Egis: Major French engineering and project management firm in transport infrastructure. Documented consortium partner with LA/BA on Brest BHNS, Nancy-Contrexéville, and ZAC projects, and increasingly delivers its own architectural services — both competitor and partner.
• Wilmotte & Associés: Established Paris architecture firm with broader portfolio but overlapping municipal, cultural, and transport-adjacent public mandates. Competes in similar concours categories and serves similar French public-sector clients.

Direct peers

• TVK: Paris-based urban planning and architecture practice focused on mobility, public space, and metropolitan-scale projects. Strong direct overlap with LA/BA's Pôle Territoires work on tramway corridors and urban transformation.
• AREP: Multidisciplinary architecture, urban planning and engineering firm with deep specialization in railway stations, multimodal hubs, and urban transport infrastructure. Operates as a direct competitor in French mobility concours and adjacent to LA/BA in scope.
• Groupe-6: Grenoble-based architecture firm working across public space, mobility, and civic buildings in France, with comparable practice scale (~70 staff) and concours-led business model. Comparable mid-sized French multi-specialist competitor.
• Richez Associés: Paris-based architecture firm with a comparable specialization in transport infrastructure and public space, designing tramway lines, multimodal hubs, and parking across France. Closest direct analogue to LA/BA's mobility-led mandate portfolio.

Others
