🏗️ Calculate the cost of your prefabricated house in just a few clicks

Building a prefabricated house is often a dream that seems simpler and faster than traditional construction. But one question always comes up: What is the cost of a prefabricated house?

Between the price of the module or kit, the foundations, the finishing touches and unforeseen events, it is difficult to have a clear idea from the outset.

💡 Why estimate the cost from the start of your project?

Save time: In just a few minutes, you get a personalized estimate. The simulator allows you to enter a number of key parameters (area, type of module or kit, type of foundation, etc.).
Real Estate Collection
Cost clarity: The tool breaks down the different components of the budget: excavation, foundation, finishes, connections, landscaping, and contingencies. This transparency allows for better anticipation of expenses.
Real Estate Collection
Adapted to the Quebec market: The values used in the simulator are calibrated according to Quebec standards, which enhances the relevance of the results.
Real Estate Collection
Flexibility: You have the option to use the basic settings or go to the "advanced" tabs to adjust the price ranges, according to your choice of finishes or site constraints.

The tool allows you to perform several simulations in order to estimate your construction costs according to several different scenarios and models.

🧰 Estimating the cost of a prefabricated house

Basic parameters
- Area (in sq ft): Indicate the total planned area of your project.
- Regional adjustment: choose a "less expensive", "standard" or "more expensive" zone to adjust the estimate according to the region.
- Module or kit price: enter the base price of your prefabricated module or kit.
- Project type: selection between "modular" or "kit/panels".
- Foundation type: slabs, crawl space, basement, piles… Each option has an impact.
- Dimensions (optional): If you know the exact dimensions (e.g., 36 × 42), this refines the calculation.
Advanced settings
- Excavation and foundation (% or $/ft²): adjust according to topography, soil or constraints.
- Installation and connections (%): electricity, plumbing, networks – often hidden costs.
- Interior and exterior finishes: choice of materials, coverings, terrace, etc.
- Exterior landscaping and equipment: landscaping, earthworks, heating, etc.
Result The tool compiles all these parameters to generate an indicative estimate of the total cost of your project. It reminds users that the results are indicative only and may vary depending on the terrain, region, or choice of finishes.

🧱 Understanding cost allocation

Each project is divided into four main stages:

Foundations (30 to 35 %)
The excavation, the concrete, the drain, the foundation walls and the slab.
Structure and envelope (≈ 30 %)
The walls, the roof, the windows and the waterproofing.
Interior partitions and walls (≈ 10 %)
The plasterboard, the paint, the moldings and the doors.
Interior and exterior finish (≈ 28 %)
Cabinets, flooring, stairs, plumbing, electricity, landscaping…

By understanding this breakdown, it becomes easier to adjust the project according to your budget.

💸 How to reduce costs without sacrificing quality

Here are some simple tips to lower the bill:

Opt for a standard model rather than custom-made: manufacturers often have optimized, more economical plans.
Choose the right foundation : a slab generally costs less than a basement.
Compare the regions : labor and transportation vary from sector to sector.
Take advantage of energy-efficient programs like Hilo or LogiVert.
Do some of the work yourself, such as painting or landscaping.

🏠 A tool to better understand and visualize the cost of a prefabricated project

Our cost simulator for prefabricated houses was designed for to help Quebecers better understand the true costs of a prefabricated construction project. Too often, budgets are vague or underestimate certain essential items. With our tool, we make the figures clear. clear, visual and accessible, by automatically breaking down each expense item — from foundations to finishes — according to Quebec market standards.

Whether you're considering a four-season tiny house, a cabin in nature, or a turnkey family home, Our simulator allows you to visualize the cost breakdown in concrete terms. and adjust your project accordingly, even before requesting quotes.
