Why convert your attic?
Converting attics is an ideal solution to expand your home while minimizing costs associated with an extension. This operation involves transforming the space under the roof into a comfortable and functional living area.
Whether you want to create a bedroom, a home office, a relaxation area, or even a separate studio, this transformation offers numerous possibilities while optimizing your real estate assets.
A gain of living space without extension
By rehabilitating your attic, you gain valuable square meters without encroaching on the garden or outdoor space. This solution is particularly suitable for urban areas and fully utilized plots.
A significant increase in your property's value
An additional, well-designed and insulated space significantly increases the value of your home. In Switzerland, potential buyers pay particular attention to optimized living areas.
The steps to a successful attic conversion
An attic conversion in Switzerland takes place in several key stages. Each phase requires specific expertise to ensure safety, comfort, and regulatory compliance.
The different possibilities for attic conversion
Attic conversions can take various forms depending on the existing configuration, the available height, and your needs. Avenir Renovations Switzerland advises you on the most suitable solutions.
Traditional framed attics often offer a large open volume, ideal for creating a living space. Generally, it is enough to install a suitable floor, insulate, and arrange the walls.
This type of framing often includes W trusses that reduce usable space. Structural modifications may be necessary to free up volume and make the attic habitable.
If your attic is too low, a roof extension can be considered. This more significant operation allows for an increase in ceiling height and provides a comfortable space.
How much do attic fit-out works cost?
The price of an attic fit-out in Switzerland depends on many factors: area, condition of the framing, choice of materials, type of rooms created, and any structural modifications.
| Type of service | Average price per m² (CHF) |
| Insulation only | 150 to 250 CHF |
| Complete fit-out without framing modification | 1,200 to 1,800 CHF |
| Fit-out with framing modification | 1,800 to 2,500 CHF |
| Roof extension with fit-out | 2,500 to 3,500 CHF |
These prices include labor, materials, and standard finishes. A personalized quote is necessary to accurately estimate your project.
Check the condition of your attic
For your attic to be convertible, certain conditions must be met: a ceiling height of at least 1.80 m, a roof slope greater than 30°, and a sturdy enough frame to support new loads.
Unlike lost attics, habitable attics generally require little heavy work such as raising walls or modifying the roof. Whether your attic is already converted or not, do not hesitate to seek the advice of renovation experts. At Avenir Renovations, we are here to provide tailored advice and support you in your project with professionalism and care.
Attic conversion work
Building stairs to access the attic, installing a heating system for the new rooms in the attic, fitting a bathroom or shower room, layout... Here are some tasks to be carried out during an attic conversion project.
Construction of the opening and staircase
One of the key points in attic conversion is to create a practical and safe access. You can choose from several options: a straight staircase, a spiral staircase, a ladder, or a Japanese step staircase.
The choice will depend on the available space, the desired style, and your budget. While a straight staircase is simple to design, it does require a lot of space. For tighter spaces, a spiral or winding staircase is an excellent alternative to save space. At Avenir Renovations, we are here to bring your projects to life and carry out all your renovation work with care and professionalism.
Installation of the heating system
For optimal comfort throughout the year, it is essential to have an efficient heating system in addition to insulation. You can choose to extend your current system, whether it runs on oil, gas, or a heat pump, as long as it is powerful enough to adequately heat the attic.
If not, it is possible to install a new heating system, prioritizing an environmentally friendly and energy-efficient solution. Do not hesitate to contact Avenir Renovations to guide you towards the best choice, tailored to your needs and budget.
Layout of the attic
Once your plans are defined, it is time to proceed with the attic fit-out. If the space is large enough, you can create several rooms by installing partitions and doors.
A wooden floor provides an ideal base for laying drywall, such as plasterboard or plaster tiles, thus facilitating the addition of doors and the creation of well-defined spaces.
Swiss regulations for attic conversion
Before starting your work, it is essential to check the regulatory feasibility of your project. In Switzerland, urban planning and construction rules vary by canton and municipality.
Administrative procedures often include submitting a building permit application, especially if the work alters the exterior appearance of the roof or impacts the building's structure. Thermal (SIA 380/1) and acoustic standards, as well as fire safety regulations, must also be adhered to.
Local permits and constraints
Each municipality may impose restrictions on maximum height, roof pitch, or the type of roof windows allowed. A prior check with the local urban planning service is therefore essential.
Insulation and habitability standards
For your attic to be considered habitable, it must meet specific criteria: minimum ceiling height, effective thermal insulation, adequate ventilation, and secure access.
