Founded in 2016 in Paris’s Quinze-Vingts district, the studio brings together Mark Havasi, Hugo Alzingre and Charles Mannenc around a shared vision: designing architecture that is contextual, narrative, and measured. The agency is based at 34 rue de Trévise, in Paris’s 9th arrondissement, working from a dense and diverse urban setting that continuously feeds its thinking and practice.
Each project begins with a close reading of its site — its geology, history, materials, and uses — forming the basis of a unique narrative specific to the place. Architectural design is approached as a layering of knowledge, bringing together programmatic, economic, territorial and climatic dimensions to produce clear, context-driven, and enduring responses.
This method gives rise to architecture that is restrained, precise, and purposeful. Materials are selected for their coherence and durability, structures for their clarity. he goal is not to impress but to serve — privileging usability over gesture, and relevance over excess. The studio works across scales and typologies — housing, offices, new builds and refurbishments — with strong expertise in timber prefabrication, occupied site construction, and ambitious energy renovation.
Atelier Quinze Vingts stands alongside clients as a committed and thoughtful partner, delivering architecture that is useful, careful, and capable of evolving. Each project is driven by rigor, responsiveness, and attention to detail — through a constant dialogue between site, structure, and use.
