What Callison Architecture does
Callison Architecture is a Seattle-based professional architecture and design firm founded in 1975 that operates as part of Arcadis N.V.'s Architecture and Urbanism division, following Arcadis's 2017 acquisition of CallisonRTKL. The firm delivers sustainable architecture and integrated design services for enterprise, developer, and government clients, combining a global network of designers, engineers, digital specialists, and environmental scientists to address urban growth, net-zero commitments, and climate resilience challenges. Its work spans complex, highly regulated sectors including high-rise residential, mixed-use waterfront, aviation-adjacent developments, and public-sector infrastructure asset management.
The firm's core offering centers on Architecture and Urbanism Services, with related disciplines in Interiors, Planning, Landscaping, and Urban Design. Notable project credentials include The Curv, a 60-story Vancouver residential tower designed to the Passive House standard and projected to use 90% less heating and cooling energy than a conventional high-rise; River Green Village, a 27-acre flood-resilient waterfront master plan in Richmond, BC that reconciles aviation glide-slope constraints with dike upgrades; and a 54-story LEED Gold tower delivering 443 residential units. The firm has also developed the Enterprise Decision Analytics Platform, a data analytics offering that consolidates fragmented infrastructure data into predictive models for public-sector capital planning, and partners with Autodesk for AI-assisted identification of hidden structural elements.
Revenue is generated through project-based professional services engagements via direct client relationships, with no disclosed pricing model. The firm serves a mix of private real estate developers (e.g., Vancouver high-rise residential, Richmond waterfront) and government clients (e.g., District of Columbia infrastructure asset management, $14B portfolio), with documented outcomes including a 54% concrete-emissions reduction for an automotive-sector client and contribution to high US municipal bond ratings for DC. Operating geographies span North America (USA, Canada) within a global Arcadis delivery network, with no separately reported revenue, headcount trend, or pricing details available in the source data.
