Is your family growing, is remote work becoming permanent, or do you dream of a brighter living space? In Switzerland, an extension allows you to gain valuable square meters while maintaining your neighborhood and habits.
The extension can accommodate a bedroom, an office, a master suite, or an independent space. For this new area to be sustainable and well integrated with the existing structure, the project must be carefully prepared.
Why expand rather than move?
Changing homes involves searching, procedures, and sometimes distance. An extension, on the other hand, adapts your house to your new way of living.
It can also improve the entire home. A new opening brings in more light, facilitates movement, and strengthens the connection with the garden. When the work respects the architecture of the building, the extension can also enhance the property's value.
Before choosing this solution, however, it is advisable to compare its cost with that of moving and to check the buildable potential of the plot.
What type of extension should you choose for your home?
A lateral extension is preferred when the land offers enough space. At ground level or on multiple levels, it can extend the living room or create a new wing.
If ground space is limited, an elevation allows for an additional floor. A study must then verify that the foundations and walls can support the new loads.
A habitable conservatory or a largely glazed extension is another option. To remain comfortable year-round, it must have effective insulation, solar protection, and appropriate ventilation. The choice thus depends on the land, the building, the budget, and the intended use.
What procedures should be anticipated in Switzerland?
Construction rules vary by canton and municipality. An extension is generally subject to a building permit. Before designing the project, contact your municipality's construction service to know the applicable regulations.
Feasibility may depend on zoning, distances to boundaries, permitted height, or heritage constraints. The file may also be subjected to public inquiry. Anticipating these elements allows for the integration of administrative timelines into the planning.
Technical points not to overlook
An extension must form a coherent whole with the house. A study of the soil and structure may be necessary to define the foundations, check stability, and prevent cracks. The connection between the new part and the existing structure requires particular attention to avoid leaks and thermal bridges.
It is also necessary to plan for network connections and check the capacity of the existing heating system. Orientation, glazing, and solar protections directly influence comfort in both winter and summer.
Finally, the exterior appearance is as important as the interior layout. Materials, roofing, joinery, and colors can create continuity with the house or, conversely, a controlled contemporary contrast.
What budget and timeline should be anticipated?
The price of an extension varies according to its size, complexity, type of foundations, materials, equipment, and finishes. An elevation or a difficult-to-access site will generally be more complex than a simple ground-level extension. Studies, fees, and administrative procedures must also be included in the budget.
To obtain a reliable estimate, the project must be defined before pricing. Allowing a margin for unforeseen events is prudent in an older home. The timeline includes design, permits, and construction.
A single point of contact for your project
An extension involves several trades: masonry, carpentry, roofing, joinery, electricity, plumbing, heating, insulation, and finishes. The quality of the result depends as much on each person's expertise as on the coordination between the participants.
With Avenir Rénovations Suisse, your Project Manager supports you from the needs assessment to the completion of the project. They analyze feasibility, prepare a detailed estimate, select professionals, and organize their interventions. This way, you benefit from a single point of contact and a clear view of progress.
