The Buchanan Complex is a landmark of Vancouver's history of modern architecture. It is a complex of simple concrete frame buildings with glazing and masonry infill panels that skilfully negotiate the site's topography, creating a series of open and covered courtyard spaces that are an extension of the built form. After nearly 50 years, the courtyards' vegetation has matured substantially, creating pleasant spaces of varying scale and light quality. In contrast, the buildings' interior spaces have not aged with the same grace.

In 2001 Busby Perkins+Will was commissioned to complete the design of the complex's upgrade. The project scope included a complete overhaul of the existing mechanical and electrical systems and a seismic upgrade of the building's structure. Interiors have been fully reconfigured to reflect current teaching techniques, including increased flexibility and more office spaces for graduate student research. These renovations combine arts student services into a convenient ground level office zone that includes co-op, student guidance and counselling. The integration of graduate students with faculty will increase the significance of the graduate experience and enhance the faculty's retention abilities. The complex will participate in the new "University City" by reaching out to the campus with more social spaces that operate around the clock, and a new café is proposed to revitalize the Buchanan West courtyard, bringing much needed pedestrian activity to this public space.

This complex is the primary facility for the Faculty of Arts. With 12,000 students enrolled, it is the largest faculty at the University of British Columbia. The project implemented sustainable features to aim for LEED Gold certification.
