Rideau Hall – Conservation and Change in a Working National Historic Site

Friday, October 13
10:30 AM - 12:15 PM

Since 1867, Rideau Hall has been the official residence and workplace of Canada’s governors general. The estate is a national historic site and Classified federal heritage complex, situated in an idyllic 79-acre urban oasis only a few minutes from the heart of the National Capital.
In 2016/2017, the National Capital Commission undertook several landmark projects designed to enhance the heritage character, the public spaces and overall quality of this remarkable landscape. The conference proposal is a panel session that would include:
- An introduction to the site, its heritage values and the conservation framework that is applied to the site (by Heather Thomson, Manager, Heritage Program, NCC)
- An overview of several significant 2017 projects by the NCC project managers, with a discussion of challenges and conservation strategies.
o The Forecourt: The forecourt of the Main Residence was revitalized in order to support its ceremonial function and improve universal accessibility, while conserving its heritage character. (Yoland Charette, Chief, Landscape Architecture, NCC)
o The Winter Pavillion: The former Dairy Building (1895), a Recognized federal heritage building was rehabilitated to give it renewed visibility and a public use. (Tom Laverty, Project Manager, Architect, NCC)
o The Chauffeur’s Garage: This attractive garage built in 1912 was rehabilitated and a contemporary addition was added to support the operations of the estate. (Mona Lamontagne, Project Manager, Architect, NCC)

We propose a one hour session for this topic, and we would also propose a separate technical site tour that would showcase these and other heritage projects at the Estate.
