ADHOC Architectes

What ADHOC Architectes does

ADHOC Architectes is a Montreal-based, privately held architecture firm founded in 2014 that delivers integrated design services across four disciplines: architecture, urban design, landscape architecture, and interior design. The firm serves residential developers and homeowners, commercial and retail clients, and public and institutional customers across Quebec and Ontario, with a portfolio spanning multi-family residential buildings, single-family homes, commercial interiors, healthcare facilities, hospitality projects, public recreational buildings, and temporary urban installations. Its practice emphasizes contextually integrated, narrative-driven design with an inclusive co-creation approach that involves clients from concept through construction ("first pencil stroke to last hammer blow").

The firm operates a multi-disciplinary team of approximately 30 professionals — including architects, interior designers, landscape architects, and support staff — that is curated for each project. Technical capabilities include LEED-accredited professionals (achieving LEED Platinum on multiple projects including La Géode and Projet ADHOC) and BIM-based technical coordination, with the firm identified among the short list of Quebec agencies mastering these techniques.

The business model is professional services on a project-based fee structure. Revenue is generated through direct project commissions, design competitions (both public and private), and developer mandates. Distribution relies on competition wins, portfolio visibility, professional network engagement, and earned media; the firm has accumulated over 40 industry awards since 2015 from bodies including Grands Prix du Design, Canadian Architect, ArchDaily, OAQ, Brick Industry Association, and Domus. Key repeat clients include Knightsbridge (developer/contractor), Technopôle Angus, Groupe VSO, and Salvation Army, with strategic partnerships including joint-venture work with Prisme Architecture (Gadbois, Baie-de-Valois) and Ædifica (Canoë). Leadership comprises Creative Director Jean-François St-Onge and Technical Manager François Martineau as co-founders.
