What Stewart Architecture does

Stewart Architecture is an integrated architecture studio offering urban design, architecture, and interior design services across Australia, founded in 1987 by Colin Stewart in Canberra and now operating from studios in Canberra (Fyshwick) and Sydney (Ultimo) with a team of 46. The firm serves three primary client verticals: government and public sector bodies (ACT Government, City of Sydney, Property and Development NSW), educational institutions (Radford College, Canberra Girls Grammar School, Daramalan College, University of Canberra), and property developers (DOMA Group, Bloc, Art Group, Elanor Investors Group). Its portfolio spans everything from heritage residential refurbishments to large-scale master plans (Kingston Foreshore, City Hill Precinct, YarraVale) and award-winning civic buildings such as the Green Square Library and Plaza, which won the Sir Zelman Cowen Award for Public Architecture.

The practice differentiates through holistic integration of urban design, architecture, and interiors rather than treating them as siloed disciplines, combined with deep expertise in sustainable design methodologies including solar-passive design, cross-laminated timber construction, water-sensitive landscape design, and heritage-responsive adaptive reuse. Notable technical achievements include delivering Canberra's first mass timber commercial office at 23 National Circuit (5.5 Nabers Energy, 6-star Greenstar) and exceeding passive design benchmarks on projects such as Akoya apartments (88% receiving 3+ hours direct sunlight in mid-winter against a 70% requirement). The firm has accumulated over 50 industry awards, including two Canberra Medallions (1997, 2025).

Stewart Architecture generates revenue through project-based professional services commissions spanning master planning, urban design, architecture, and interior design, typically structured as fixed-fee arrangements. Go-to-market is anchored in design competitions (both invited and open), direct client engagement, and long-term repeat relationships with developers and institutions such as DOMA Group (four+ projects), Radford College (three+ projects), and Bloc (three+ projects). Marketing channels combine a project-rich website, Instagram and LinkedIn presence, newsletters, and active participation in Australian Institute of Architects awards. Leadership is provided by Practice Principal Marcus Graham and Director Felicity Stewart (founder's daughter), supported by associate directors and senior associates across both studios.
