How much does it cost to add a new floor or an extension?

The cost of a floor addition or extension depends on many factors, such as the surface area of the work, the materials selected, the configuration of the existing building and access constraints. As each project is unique, it’s essential to consider your family’s specific needs, the municipal standards in effect in Montreal, and the aesthetic and technical choices made during the planning stage. Whether you’re planning a vertical or horizontal extension, a good evaluation will help determine a clear and realistic budget.

At Construction Précellence, we work with you right from the start to provide detailed costing for each stage, so that you get a project with no surprises and perfectly aligned with your expectations.

What are the factors that influence the price of your project?

The final cost of a floor addition or extension is determined by a combination of technical, aesthetic and structural factors. The surface area added, the complexity of the work, the condition of the existing building, the materials chosen, and the modifications required to the first floor or roof all play a key role in determining the budget. Added to this are municipal requirements, necessary permits, site access constraints and the estimated duration of the work.
