Why choose a house extension?

A home extension is ideal for :

  • Add an extra room, such as a bedroom for a new child, an en-suite bathroom or a more spacious, functional kitchen.
  • Create a light-filled space by adding a glass roof, a solarium or an extension with large windows, perfect for enjoying natural light all year round.
  • Enlarge a garage or living room, to accommodate an extra vehicle, storage space, or simply to offer more comfort and fluidity to your living area.

These prices include materials, labor and permits, but may vary according to your specific choices. Factors such as premium finishes, structural upgrades, complex design elements, or custom architectural features can all influence the final cost. Additionally, the timeline, accessibility of the site, and any unexpected conditions discovered during the home extension project may also lead to adjustments. That’s why working with an experienced general contractor like Construction Précellence ensures full transparency and precise budgeting from day one.

What factors influence the price of an extension?

The final cost of your home extension depends on a number of criteria: the surface area added, the complexity of the work, the condition of the existing structure, the materials selected, the need for specialized labor, and the adjustments required to the interior of the house. Other factors such as site access, deadlines, administrative procedures and architectural features can also influence the overall budget. A complete analysis by an experienced general contractor will help you obtain a fair and realistic estimate.

  • Type of project: Side extension, adding a new floor or sunroom.
  • Materials: insulation, finishes, doors and windows.
  • Complexity of work: Structural adjustments (foundations, roof).
