Nu ‎• Architectural Design & Engineering Firm

What Nu ‎• Architectural Design & Engineering Firm does

Nu Architecture & Ingénierie is a Paris-based dual-practice firm founded in 2019 by Thibaut Dubegny and Grégoire Arthuis, operating simultaneously as an architecture agency and a structural engineering office (bureau d'études structure). The firm specializes in pedestrian and vehicular bridges, footbridges, ecoponts, and adaptive/circular buildings, serving predominantly public-sector clients — municipal governments, metropolitan authorities, port authorities, and transit agencies — across France, Germany, Italy, and Belgium. Core projects include the award-winning Passerelle sur le Doron at Brides-les-Bains (20m mirror-polished stainless steel), the IGA 2027 footbridges in Lünen, the Viaduc sur la Meduna in Pordenone (€35M construction value), and the 65 Logements Mutables housing development in Angers.

The firm's technical backbone is a fully integrated BIM workflow running Rhino 3D with Grasshopper for parametric concept design, Autodesk Revit for production documentation, SOFiSTiK for structural dimensioning, Enscape for real-time visualization and VR, and Solibri for IFC model review. Co-founder Thibaut Dubegny's role as the official SOFiSTiK representative in France provides privileged structural-analysis integration. The firm's differentiation rests on its dual-culture team — combining state-architect credentials (HMONP, ENSA Paris-Malaquais) with civil engineering (ESTP, TU Dresden, INSA Lyon) — enabling integrated design where structure and architecture evolve simultaneously rather than being overlaid sequentially.

Nu generates revenue through professional design fees on public infrastructure and building commissions, typically acting as mandataire (lead firm) of project consortia with specialist engineering, landscape, and construction partners. Projects are acquired exclusively through architectural competitions (concours) and public tenders, with construction budgets on its portfolio ranging from €0.3M to €35M. The firm operates from Paris (headquarters, 19th arrondissement) and Angers, with a current headcount of 17 employees and estimated annual revenue of €1–5M (not publicly disclosed). It is entirely founder-owned, self-funded, and carries no external investment or institutional backing.

Revenue model

1. Architecture and engineering design fees: Revenue is generated through professional fees for architectural design and structural engineering services on public infrastructure and building projects. Fees are earned as a percentage of construction cost or as fixed-price commissions on awarded projects (concours, études, maîtrise d'œuvre). Projects range from small footbridges (0.3 M€ construction cost) to large viaducts (35 M€), with firm fees scaled accordingly. As mandataire of consortia, Nu earns a lead-firm share while subcontracting to partners (engineering consultancies, landscape architects).

Functional benefit

Products and services

• Pedestrian Bridges (Passerelles) Integrated architectural and structural engineering design of pedestrian and cycle footbridges for urban mobility and soft-traffic connectivity, using steel, stainless steel, timber, prestressed stone, or mixed-material structures. Targeted at municipal governments, metropolitan authorities, and public institutions seeking urban connectivity across rivers, railways, roads, and canals.
• Vehicle and Multi-modal Bridges (Ponts) Architectural and structural engineering design of vehicle and multi-modal bridges for road, rail, and port applications, including movable bridges (Scherzer-type), beam bridges, and innovative span configurations. Targeted at public-sector clients and infrastructure operators requiring complex structural design combined with architectural expression.
• Green Corridor Bridges (Ecoponts) Design of ecoponts (ecological corridor bridges) that allow wildlife and biodiversity to cross major infrastructure (motorways, urban barriers), integrating landscape architecture and biodiversity features. Targeted at metropolitan and regional governments commissioning green infrastructure projects.
• Adaptive / Mutable Housing Design Architectural and structural design of residential housing with flexible, mutable floor plans engineered to adapt to future uses, using post-slab concrete or adaptable structures that allow conversion of space (e.g., ground-floor parking to commercial) without structural intervention. Targeted at public and private developers seeking buildings with long-term adaptability and low-carbon construction.
• Demountable / Adaptable Parking Structures Design of demountable and reusable parking structures that can be converted into public halls or other uses, using reclaimed steel frames and adaptable systems where envelope and structure are functionally independent. Targeted at public housing authorities and metropolitan development operators.
• Cultural Facility Design (Conservatoires and Theatres) Architectural and structural design of cultural facilities combining music, dance, and theatre spaces with shared open areas that promote discovery and social encounter. Targeted at municipal governments commissioning cultural infrastructure.
• Educational and Pedagogical Facility Design Architectural and structural design of educational and pedagogical facilities, including temporary modular structures with observation bridges and learning spaces. Targeted at transit authorities and public institutions commissioning on-site training and educational centers.
• Sports Facility Design (Clubhouses) Architectural design of sports clubhouses and ancillary facilities engineered to host multiple activities, with structural solutions enabling wide roof overhangs for all-weather outdoor use. Targeted at municipal and private sports clubs or operators.
• Office Building Rooftop Extensions and Rehabilitation Architectural and structural design of office building rooftop extensions and rehabilitations that reinterpret existing structural patterns, with emphasis on material reuse (retaining original brick walls, staircases) and timber-structure extensions. Targeted at private commercial property owners and developers.

Quantifiable outcome

• 65-logement mutable housing project delivered with post-slab structure enabling ground-floor parking to convert to commercial use without structural intervention, anticipating Angers PLU evolution.
