What Diamond Schmitt Architects does
Diamond Schmitt Architects is a privately held, Toronto-headquartered architecture firm with offices in Toronto, Vancouver, and New York. The firm specializes in designing institutional, cultural, healthcare, academic, and civic buildings for public-sector and major-institutional clients, including universities (University of Toronto, McGill, McMaster, Ontario Tech, Emily Carr), hospital systems (SickKids, Michael Garron, St. Michael's, Hamilton Health Sciences, Fraser Health), federal and municipal governments (Senate of Canada Building, OPL-LAC Joint Facility, National Arts Centre), and cultural institutions (Lincoln Center, Art Gallery of Ontario, Buddy Holly Hall). Landmark projects include the Four Seasons Centre for the Performing Arts, the reimagined David Geffen Hall, the Peter Gilgan Centre for Research and Learning at SickKids, the Temerty Building at U of T, the McGill Sustainability Park (adaptive reuse of the Royal Victoria Hospital), and the OPL-LAC Joint Facility Ādisōke.
The firm's core offering is comprehensive architectural design services spanning feasibility studies through design and construction administration. Its technology and methods centre on Building Information Modeling (BIM), open BIM workflows, and ISO 19650-compliant digital practice, under a Director of Digital Practice. Specialized technical competencies include concert-hall and performing-arts acoustics (notably the "surround hall" redesign of David Geffen Hall using 22 motorized lifts for flexible orchestral, film, opera, and pop configurations), healthcare facility design, heritage renovation and adaptive reuse, computational design for fabricated features (e.g., beaver-dam-inspired reclaimed-ash diagrid panels at Ādisōke), and sustainability frameworks targeting LEED Gold/Platinum, Passive House standards (AGO Dani Reiss Gallery), Net Zero Carbon certification, and RHFAC Gold accessibility ratings.
Revenue is generated through professional design fees on a project-by-project basis, with commissions typically secured via design competitions, competitive RFP/RFQ processes, and reputation-based referrals. The firm pursues long-duration institutional commissions where government funding is a key lever for public-sector work; pricing and project fees are not publicly disclosed. Brand prestige is actively reinforced through media coverage (The New York Times, Architectural Record, Dezeen, Forbes, Globe and Mail), awards (AIA, OAA, RAIC, Canadian Architect, Civic Trust), and strategic co-design partnerships with MVRDV, Selldorf Architects, Two Row Architect, Lemay Michaud, and KWC Architects to combine specialty expertise on large commissions.
