Collègues travaillant ensemble


Three words summarising the approach COHESIO uses to turn its clients’ vision into concrete projects.

Comprehend Our clients praise our ability to listen to and understand their true needs. Thus, our team of experts is able to develop concrete solutions with performance, aesthetics and cost optimization in mind. 

Design Using their technical expertise and creativity, our team design spaces made to perfectly address the constraints specific to each project, and to answer both the clients and the end users needs.

Build In addition to maintaining close collaboration between all the experts involved in a project, we rigourously supervise the construction site and the quality of all our projects. 

2/3 and 4 Place Ville Marie

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

COHESIO 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.

Kashechewan school

COHESIO, 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.

Confidential data center

Since 2017

COHESIOis 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.
