Site preparation and foundations : one of the most important step to buildin your future home


Application for a building permit on your residential plot

Before any work begins, it’s imperative that your building contractor obtains approval from the municipality or city to build your new home. This stage provides precise details of the entire project and usually comprises 5 elements:

  • Preparation and research : Does your project comply with the municipality’s zoning bylaws? These regulations determine the types of residential construction permitted, the distances to be respected in relation to property boundaries, the maximum height of buildings, etc. Certain zones may have additional requirements.
  • Preparing the necessary documents : You’ll need to provide detailed plans for your project. These plans must include elevations, foundation plans, floor plans, etc. A detailed written description of your project may also be required. Depending on the nature of the construction, additional documentation may be required, such as an environmental assessment, a stormwater management plan, proof of land ownership, etc.
  • Submission of application : Complete the building permit application form provided by your municipality. This form generally asks for information about the owner, the project location, and project details. Payment of the application fee is often required at the time of filing. These fees vary according to the size and type of project.
  • Evaluation of the building permit application : your application will be reviewed by the municipal planning department to ensure that it complies with all applicable by-laws, building codes and other requirements. You may have to make changes to your project to meet municipal requirements.
  • Obtaining the permit : Once your application has been approved, you will receive your residential building permit. This permit generally specifies the conditions to be met and may limit the period of validity of the permit.

Allow time for this step, as obtaining a permit can take several weeks or more, depending on the complexity of the project and the volume of applications processed by the municipality.


The foundation, is one of the most important step to building a house and in a new home construction process.


Levelling and site preparation

The transformation of the construction site begins with clearing and excavation by a specialized team. This preparatory work ensures that the site is ready for the foundation of your home, by removing rocks and debris, and preparing the ground for essential installations such as the septic system.


Foundation pouring

The foundation is the backbone of your home, providing a solid support on which the rest of the construction can rise. Whether you’re building a full basement or a slab foundation, this very important stage of home construction will ensure the durability and stability of your home. The foundation step to building a house also includes waterproofing and installation of sub-slab installation of sub-slab plumbing and electrical components, and installation of the drainage system.


Economic importance and deadlines

The foundation represents a significant proportion of the new-build budget, with costs influenced by various factors such as climate, soil type and building area. In Quebec, where the elements can vary greatly, it’s best to allow for some leeway. This phase usually takes up to a month, underlining its importance and complexity.

The foundation is the first critical step in building a new home. It’s the foundation for everything that comes after.


For more details on the factors that contribute to the cost of a new construction foundation, we invite you to consult our article : 8 key factors influencing the cost of a new house foundation

Carpentry is something we always hear a lot about from our customers. The floor system, walls and roof form the shell of your new home. This phase transforms the building project into a recognizable structure, paving the way for the next steps that will make your house a home.


Shell construction

Framing establishes the shape and structure of your home. Plywood or oriented strand board is generally used to assemble and close the exterior walls and roof, followed by the installation of windows and exterior doors.

At this stage in the construction of your new home, your choice of doors and windows becomes crucial. Doors and windows obviously contribute to the aesthetics of your new home, but above all they’re vital to the thermal insulation, security and comfort of your home.

At Harmonie Construction, we make a point of guiding you towards choices that not only align with your preferences in terms of “style”, but also effectively meet your requirements in terms of energy performance and longevity, and our high standards.

Complete installation of plumbing, electrical and HVAC systems

At this step to building a house, the project is progressing well and the vision of a functional home is taking shape with the installation of plumbing, electrical and air-conditioning systems. Carrying out this work calls for a wide range of skills and expertise, requiring excellent coordination and cooperation at all times. A general contractor with a good reputation who works regularly with the same teams will be an invaluable asset for the rest of your project.



Essential systems integration

Once the main structure of the house is complete, the specialists begin meticulously integrating the pipes, electrical wiring and ducts for the heating, ventilation and air-conditioning (HVAC) system.

Vital elements such as sewer lines, air vents, water supply lines, and bathtubs and/or shower bases will be installed at this stage to take advantage of the open space to handle bulky and heavy equipment more easily.


Safety first

The electrical installations then take shape, with the installation of receptacles for sockets, lights and switches, as well as the necessary wiring for telephony (less and less frequent), cable or fiber TV, and audio systems when required. Plumbing and ductwork for air-conditioning and forced-air heating are given priority over electricity to simplify the layout of the installations.



Budget and financial considerations

Unfortunately, the scale of these installations is reflected in the budget, with costs for general plumbing ranging from $8,000 to $12,000, and for electricity from $2,500 to $4,000 on average in Quebec.

Construction schedule

Although installation of the air-conditioning system is relatively quick, All plumbing and electrical/ventilation (HVAC) work requires a great deal of attention, and can take from two to four weeks to complete. The progress of this phase is also subject to several inspections before the walls are closed, to ensure that the construction complies with building codes and the rules of the trade.

Regulatory inspections

Inspections play a strategic role, with three separate checks on structural, plumbing, electrical and mechanical installations. These checks guarantee safety and construction conformity before moving on to the final stages, such as the installation of gypsum board, a preview of the interior finishing work.

The performance of each layer of insulation is measured by its R-value, which quantifies its ability to resist heat transfer, an essential element in guaranteeing year-round comfort and reducing energy costs in Quebec.


Choice of materials

A wide range of insulation materials offers flexibility to suit every project. Whether it’s fiberglass, cellulose for horizontal surfaces with its excellent ability to accumulate and release moisture, foam, or solutions such as mineral wool and insulating concrete forms, each type has its advantages, specially selected to match the climate and specific requirements of your building.

The use of spray urethanefor example, while more expensive, offers excellent R-value and the ability to seal tight spaces against air leakage.


Thermal insulation applications and techniques

Insulation is applied in exterior walls, the attic, and floors above unfinished areas such as basements, necessary to ensure complete coverage.

The choice between blanket or blown insulation depends on the configuration of the house and the energy efficiency objectives being pursued. The addition of a vapour barrier also helps control humidity, protecting the structure from potential water damage.

Budgetary considerations : The investmentThe insulation thickness varies greatly, influenced by the type of insulation chosen and the size of the house. For a 2,000 sq. ft. new build, the cost can vary from $3,000 to $10,000, with significant variations depending on the specifics of the project.

Although this stage of home construction can represent high initial costs, it can save you money on energy bills in the long term. That’s why it’s so important to choose the right materials and techniques for your needs. Don’t hesitate to talk to your contractor.

Lead times : Insulating a complete new house usually takes between one and two weeks, depending on the complexity of the project and the type of insulation used.
