Catherine St-Marseille

Partner, Architect, OAQ

Catherine St-Marseille graduated from the Université de Montréal’s School of Architecture in 2005. She joined the practice of Provencher_Roy in 2016 and became a partner in 2021. Her participation in all three development phases of the Quartier des spectacles as well as the Promenade Samuel-de-Champlain in Quebec City led her to consolidate her knowledge in urban design, from design to site supervision. Her commitment to civic spaces and interest in public art led her to co-found the CHÂSSI collective in 2010. The group of planning professionals designs public events and pop-up installations, promoting art, culture and design..

Whether she is in charge of design, project management or production, Catherine St-Marseille has developed a solid expertise in the multi-residential sector by accumulating large-scale mandates, for which she sometimes ensures BIM and multidisciplinary coordination. Eager to innovate in terms of building systems and sustainable development, she is overseeing the development of TAK Village, a group of townhouses whose structure and exterior cladding emphasize the use of wood, as well as the Arbora commercial and residential complex built with CLT that won a Cecobois Award of Excellence in 2021. Member of the Industrial Research Chair on Eco-responsible Wood Construction (CIRCERB) at Laval University since 2018, Catherine is a regular speaker on the benefits and challenges of wood construction in Quebec (Canada Green Building Council; Woodrise Congress).
