Broad incumbents

• Dominique Perrault Architecture: Established Paris practice with major public, cultural and urban commissions (Bibliothèque nationale, Olympic projects). Comparable in public-sector orientation and urban-planning scope, but at substantially larger scale.
• Ateliers Jean Nouvel: Major French practice with extensive public and cultural commissions globally (Louvre Abu Dhabi, Philharmonie de Paris). Overlaps in cultural and public architecture but operates at much larger scale and budget tier.
• BIG (Bjarke Ingels Group): International firm with extensive cultural, educational and public commissions. Comparable in cultural and educational building typologies but operates at vastly larger scale and fee tier.
• Snøhetta: Multidisciplinary studio with a public/cultural architecture focus and strong sustainability positioning (SFMOMA expansion, Norwegian National Opera). Overlaps in public commissions and bio-based/material experimentation, though at far larger scale.
