What RDH Architects does
RDHA is a Toronto-based architectural design firm founded in 1919 (as Rounthwaite, Dick & Hadley Architects Inc., rebranded to RDHA in 2018) with a 100+ year legacy in Canadian architecture. The firm operates as a single integrated studio offering professional services across seven practice areas: Cultural (libraries, art galleries), Education (universities, academic buildings), Industrial (operations centers, municipal facilities), Office (corporate headquarters), Recreation (sports facilities, aquatic centers), Secure (diplomatic facilities), and Transit (train stations, transit infrastructure). Notable project experience spans the Hazel McCallion Central Library Revitalization, Springdale Library and Komagata Maru Park (LEED Gold), FitzGerald Building Revitalization with OMA New York, Lawson Centre for Sustainability with Mecanoo, SkyTrain Operations Control Centre 2, and Canadian Chanceries in Dhaka and Abuja.
RDHA generates revenue through professional architecture fees for design, construction administration, and project management services on institutional, commercial, and public-sector projects. Pricing is project-by-project, typically procured through competitive bidding, RFPs, public tender processes, and direct commissions from government agencies, educational institutions, and municipal clients. Revenue mix is heavily weighted to Canadian public-sector institutional clients (universities, municipal governments, transit authorities, libraries), with the firm positioned as Architect of Record for international design-led partners on signature projects.
The studio is led by three principals (Bob Goyeche, Tyler Sharp, Geoff Miller) and supported by senior technical staff including a BIM Manager and IT Manager. RDHA has accumulated over 100 provincial, national, and international design awards, including five Governor General's Medals in Architecture, the 2018 RAIC Architectural Firm Award, and a record 21 awards in 2025. The firm is privately held, headquartered at 213 Sterling Road, Toronto, with no disclosed parent company, funding rounds, or external investment.
