Scope and Content

Project series documents Cornelia Hahn Oberlander's for an unrealized green roof proposal for Roy Thomson Hall, a concert hall in Toronto, Ontario. The concert hall was originally known as the New Massey Hall and was designed by Arthur Erickson in the early 1980s. Oberlander worked on this project in 2011 with architectural firm Keith Loffler McAlpine Architects. The project consisted in the revitalisation of the building for its 30th birthday and as a tribute to Arthur Erickson. The project included the addition of the green roof, which was initially part of Erickson's design. The green roof was planned to cover the four flat corners of the square base of the building.

The project series only contains a few sketches, including landscape plans, and rendering for the roof garden. The project is also documented through correspondence with architects, and project proposals.
