The creation or replacement of a framework is an essential step in the construction or renovation of a house in Switzerland. This intervention may also become necessary when the roof structure shows signs of weakness, such as cracks, water infiltration, poor thermal insulation, or sagging of the roof. Before starting the work, it is important to accurately assess the budget required for a framework, as it depends on several technical parameters.
To successfully carry out your project, Avenir Renovations Switzerland assists you in choosing and implementing your roof structure. Our specialists advise you to select the solution that best fits your home and your budget constraints.
The renovation of a framework intended for lost attics improves the thermal performance of the housing while reinforcing the solidity of the roof. This solution is also an effective way to preserve the structure of the building without incurring excessive expenses.
The budget mainly depends on the surface area of the roof, the type of wood chosen, and the complexity of the work.
In Switzerland, the average price of a framework for non-convertible attics is generally around 95 CHF per m² excluding installation. The cost of installation is then added depending on the accessibility of the site and technical constraints.
Hiring a qualified professional ensures compliance with standards and a durable structure.
The realization of a framework in attics intended to be transformed into living space requires specific expertise. The work must incorporate various elements such as technical passages, thermal and acoustic insulation, or even the possible installation of roof windows.
These elements directly influence the final cost of the project.
On average, the installation rate of a framework in Switzerland varies between 76 CHF and 95 CHF per m², depending on the complexity of the site and the necessary adaptations.
The price of materials also depends on the type of structure chosen: wooden truss, traditional framework, or metal structure. However, this type of project allows for the creation of additional living space and increases the value of the property.
| Types of work | Average price/m² |
| Supply and installation of a truss framework | 95 CHF |
| Installation of a metal framework | 76 CHF |
| Traditional framework materials and installation | 190 CHF |
| Installation of a framework for flat roofs | 152 CHF |
| Framework for lost attics including installation | 114 CHF |
Widely used in recent constructions, the truss frame is appreciated for its lightness and quick installation. It also offers a good compromise between strength and cost.
This type of structure is particularly suitable for standard roofs as well as non-convertible attics.
In Switzerland, the price of a truss frame generally ranges from 38 CHF to 67 CHF per m² for supply. With installation, the total budget can reach around 124 CHF per m².
A personalized project analysis allows for price adjustments based on the area and configuration of the roof.

The traditional frame is often favored for its aesthetics and robustness. It highlights the roof structure and offers more possibilities for fitting out the attic.
Its more complex design, however, involves a higher cost than that of a truss frame.
The price of materials can reach around 105 CHF per m². With installation carried out by a professional, the total budget is generally around 200 CHF per m².
This type of frame is particularly suitable for renovation projects of old houses or high-end constructions.
Flat roofs are increasingly used in contemporary architectural projects. They are often chosen for creating a terrace or for extending a home.
The cost mainly depends on the material used and the total area to be covered.
Supplies generally range from 29 CHF to 57 CHF per m². With installation carried out by a professional, the total budget can reach around 143 CHF per m².
Depending on needs, it is possible to opt for a structure made of wood, concrete, or steel, each material having specific characteristics in terms of strength and insulation.
The metal frame is appreciated for its high strength, durability, and quick installation. It adapts particularly well to large spans and modern constructions.
The price depends on the roof configuration, the number of slopes, the planned insulation, and any potential work to remove the old structure.
In Switzerland, the purchase cost of a metal frame generally ranges from 71 CHF to 162 CHF per m². Installation costs can add about 95 CHF per m² depending on the complexity of the site.
To obtain an accurate estimate, it is recommended to conduct a technical study directly on site.
