Presentation of the solution
The wooden frame elevation involves creating a lightweight wooden structure mounted directly on the existing load-bearing walls, after the roof has been removed. These elements, often prefabricated in the workshop, allow for a quick construction process, reducing nuisances and providing an aesthetic finish that perfectly integrates with the existing structure.
Steps of a wooden frame extension project
Each step of the project is crucial to ensure a final result that perfectly meets your needs, requirements, and quality expectations.
Why choose wooden framing?
Choosing wooden framing for your extension means benefiting from a lightweight solution that is quick to implement, efficient in insulation, environmentally friendly, and aesthetically pleasing, perfectly suited to all styles of housing.
Wood has remarkable lightness, being about five times lighter than concrete. This characteristic significantly reduces the need for foundation reinforcements, simplifying preparatory work and shortening the overall duration of the project for a faster and more efficient completion.
Wood, when combined with external insulation, ensures very good thermal comfort. This combination allows for satisfactory thermal inertia, helping to maintain a stable and pleasant indoor temperature throughout the year.
Wood is a renewable material, making it an eco-friendly option. Its use helps reduce CO₂ emissions, especially when compared to materials like concrete or brick, which are more energy-intensive and polluting to produce.
Wood offers a wide variety of finishes, whether natural or composite cladding. Whether you prefer a contemporary or traditional style, this solution harmoniously integrates with the aesthetics of your home, enhancing its unique character.
How much do house extension works cost?
The cost of an extension mainly depends on the desired level of finish, ranging from a basic wooden structure to a fully equipped extension, thus allowing the project to be adapted to your budget and specific needs.
| Type of service | Average price per m² * | Notes |
| Structural work only (wood structure, roofing) | 1,500 to 2,000 CHF/m² | No interior finishing |
| Fully equipped wooden extension | 2,000 to 4,000 CHF/m² | Including finishes, insulation, network, and joinery |
Value arguments for French-speaking Switzerland
In French-speaking Switzerland, wooden frame elevation offers numerous specific advantages, tailored to local constraints and homeowners' expectations, combining practicality, comfort, and property value enhancement.
Suitable for urban areas
The elevation provides the opportunity to expand living space without encroaching on the land area. This solution is particularly suitable for municipalities where plots are narrow, thus optimizing construction without sacrificing outdoor space.
Space gain without moving
Before selling and buying a larger property, the wooden solution allows for an increase in living space while remaining in place. This extension also enhances the property's value, offering a profitable and sustainable investment without the need to move.
Optimal thermal comfort
The process complies with Swiss energy performance standards thanks to effective insulation. It also takes advantage of the natural inertia of wood, ensuring optimal thermal comfort and better energy efficiency.
Controlled and less invasive construction
Prefabrication reduces the duration of the construction site as well as noise nuisances and on-site presence. It often allows residents to remain in the house during the work, providing comfort and practicality for the occupants.
FAQ
