Coarchitecture

What Coarchitecture does

Coarchitecture is a Quebec City-based professional architecture firm founded in 1976 as Les Architectes Hudon & Julien and rebranded under its current name in 2011. The firm operates under 10 associates and a multidisciplinary team of architects, technologists, administrators, accountants, and site supervisors, serving public-sector bodies, municipalities, and large institutional and corporate clients across Quebec. Its work is organized around three primary building types — cultural (libraries, performance halls, exhibition spaces, including the Espace Rivière cultural center for Ville de Montréal), administrative and institutional (CNESST headquarters, La Capitale, BAPE, Lobbyisme Québec, SQI), and technological / high-tech industrial — with educational facilities added as a fourth sector in 2020. Notable project examples include the Théâtre Le Diamant, the PEPS expansion at Université Laval, and the Delta III building (Quebec City's first LEED Gold certification, 2010).

The firm's technical stack centers on Building Information Modeling using Revit (since 2007) and AutoCAD (pioneered in 1985 since 1985), augmented by building-science capabilities including life cycle assessment, thermal envelope resistance simulations, and visual comfort analysis. It holds LEED, WELL, and OAQ-aligned credentials, has delivered over 20 LEED-certified projects at varying levels, and authored the Guide de la transformation du milieu de travail for the Société québécoise des infrastructures (SQI), positioning it as a national reference in Activity-Based Workplace (MTAA) design.

Coarchitecture generates revenue through project-based professional services engagements delivered directly to enterprise and government clients, with public-sector work acquired via formal RFP/tender processes. Pricing is not publicly disclosed and depends on scope and complexity. The firm is privately held by its partners with no external investors, no M&A history, and no disclosed revenue figures; operating geographies remain concentrated in Quebec.
