Current projects

2/3 and 4 Place Ville Marie

Started in April 2016 - 200,000 sq. ft.

Kashechewan school

JBC Architectes, in a consortium with STOA Architecture, has started the design and construction project for Kashechewan nation’s new elementary school, established in Northern Ontario. The new building, built on a different site than the current one, must respect future development plans that anticipate the relocation of both the school and the entire village on a new site within the coming years. This project of significant importance for the local community includes the construction of a new building formed with two aisles connected by a gateway. Footbridges built on both streets bordering the site will provide access to these aisles.

Since 2017

Confidential data center

Started in February 2019

JBC Architectes is replacing the windows and the Indiana limestone-clad envelope of this building located Place Ville Marie. The two entrances are also being redesigned. Built at the end of the 1950s, the building is in the heart of an area of outstanding patrimonial value in downtown Montreal. This significant project has required developing the most efficient and least intrusive protocol possible, to avoid disturbances for tenants and to limit costs while ensuring a fast project delivery.

JBC Architectes is currently working on the expansion of a data center located inside one of downtown Montreal’s most prestigious buildings. This complex project involves creating an additional level to the existing building and expanding by over 107.000 sq. ft. the current IT center. Three generators have been added to the data center, and 600 tons of coolant have been set up to ensure a smooth functioning. An architectural fence installed on the roof keeps the machinery hidden. 


JBC Architectes offers a complete range of professional services in architecture and interior design for commercial, industrial, realty and institutional projects of various scales.

We also provide tailored solutions to more specific challenges such as designing data centers and controlled/protected environments, maintaining and rehabilitating facades and managing property inventory.
