The Windsor Building, located at 1170 Peel Street, opposite Dorchester Square in downtown Montreal, has more than a century of built heritage in Montreal. At the top of its historic facades is a two-storey attic roof topped with copper-clad dormers and oculi. At the end of their useful life, mansard roofs were the subject of a rehabilitation project started in 2013. Historical and technical research guided the design of this project.
This includes: the reintroduction of cut slate tiles (individually nailed) as an overlap to recover the original material; the replacement of all hand-made copper tinsmithing on dormers, oculi, cornices and parapets, including the faithful reproduction of the original ornamental works; the analysis and transformation of the constructive technique including stripping and reconstruction of the entire composition of the envelope to minimize ice formation on the slopes of the mansard.
This intervention restores the historical and monumental character of the building, ensuring its durability for its second century of existence.
