Scope and content:
Project series documents Cornelia Hahn Oberlander's landscape project for the Canadian Chancery on Pennsylvania Avenue, in Washington D.C. Oberlander worked in this project from 1983-1989 with architect Arthur Erickson. Oberlander and Erickson received the National Landscape Award for the project landscape design. The design included a paved courtyard accessible through Pennsylvania Avenue and John Marshall Place Park. Oberlanded connected the park, designed by landscape architect Carol L. Johnson in 1983, to the Chancery site by adding a paving area in place of the closed street separating the two blocks. A terraced façade featuring a hanging garden with trees and roses was design as a way of extending the John Marshall Park up to the roof of the building.

The project series contains sketches and working drawings for the landscaping, including planting plans, irrigation plans, planters details, sections and planters irrigation plans, and architectural plans provided for reference use. It also contains photographs of the building and the courtyard landscaping. The project is also documented through textual records, including concept notes by Oberlander, correspondence with clients, architects, suppliers and consultants, specifications, meetings notes, financial documents, promotional material and articles on the project.
