Why choose a brick house extension?
Before delving into the details of the construction steps, it is essential to understand why a brick extension stands out as an ideal solution in French-speaking Switzerland. This traditional material is appealing due to its robustness, longevity, and ability to integrate harmoniously into both urban and rural environments. Its high thermal inertia ensures excellent indoor comfort throughout the year, limiting temperature variations in both summer and winter. Additionally, brick offers natural acoustic insulation, enhancing daily well-being. Aesthetically, it provides a timeless charm that enhances both old and contemporary buildings. Furthermore, it meets the strict requirements of Swiss standards regarding energy efficiency and environmental performance. Durable, reliable, and elegant, brick is therefore a relevant choice for any house extension wishing to combine comfort, respect for the local built environment, and long-term thermal efficiency.
The technical and architectural advantages of brick
Thanks to its stability, brick allows for solid structures without deformation. It promotes excellent thermal inertia, limiting temperature variations and contributing to a pleasant indoor environment in all seasons. With its traditional or contemporary aesthetic, it adapts to all styles and harmonizes with existing facades. Moreover, brick is a sustainable choice: when properly maintained, it ensures a longevity equivalent to or even greater than that of traditional masonry constructions.
A controlled construction site adapted to the region
The climatic conditions of French-speaking Switzerland require adapted construction solutions. Brick, combined with effective insulation and careful finishes, meets Minergie requirements or cantonal standards. Each project is analyzed according to your geographical situation, your municipality, and its urban planning regulations. We also integrate energy aspects to reduce heating consumption and ensure a good carbon balance.

Before starting the work, each project goes through a rigorous preparatory phase. Here are the key steps, ensuring complete and smooth support.
Benefits of a well-executed brick extension
To conclude this section, let’s summarize what you gain when a brick extension project is carried out with rigor and expertise:
Brick offers a durable structure, resistant to weather, thermal shocks, and external aggressions. It is a reliable material that retains its mechanical properties for several decades.
Thanks to its natural inertia, brick regulates temperature variations inside the home. It thus contributes to good energy performance and constant comfort throughout the year.
Brick is appealing for its elegant appearance, which transcends time without going out of style. It integrates well with both old buildings and contemporary architectures.
A brick facade requires very little maintenance when well designed and protected. Its durability helps limit costly interventions over time.
The brick complies with the architectural and landscaping constraints of the Swiss Romande municipalities. It adapts to the volumes, colors, and traditional styles of regional buildings.
How much do brick extension works cost in French-speaking Switzerland?
Before getting started, it is better to have a realistic idea of the necessary budget. Here is an indicative estimate of costs per square meter including tax, depending on the type of extension:
| Type of brick extension | Average price per m² including tax (CHF) |
| Simple brick extension | 1,600 to 2,200 |
| Brick extension + exterior finishes | 1,900 to 2,500 |
| Brick elevation | 2,300 to 3,000 |
These estimates depend on several parameters: the projected area, the desired level of finishes (decorative coating, high-end joinery, enhanced insulation), the configuration of the land, site access, as well as the specific requirements of your municipality or canton.
FAQ: frequently asked questions about brick extensions
Before concluding, here are answers to the most frequently asked questions by our clients. This will help you gain clarity and anticipate the steps of your project.
Is a brick extension suitable for my old house?
Yes, brick is perfectly compatible with old buildings. It is simply necessary to analyze the existing structure, check the load-bearing capacity of the foundations, and adapt the connections to the existing walls to ensure the stability of the whole.
Is it more expensive than wood?
Generally, brick is more expensive per square meter than wood framing, mainly due to the weight of the material, masonry, and construction time. However, it offers lasting thermal inertia and a timeless aesthetic that enhances the investment in the long term.
Are the timelines longer than with a wood extension?
Yes, a brick extension requires more time, especially for the structural work and drying times. Nevertheless, with good planning, timelines can be managed, and the construction site can be organized to limit inconveniences.
Can thermal insulation meet Minergie standards?
Absolutely. By combining brick with effective insulation, whether internal or external, certified joinery, and controlled ventilation, we easily meet Minergie requirements or current cantonal standards.
Can I do some finishes myself?
Yes, if you wish. We offer flexible options where you can take care of simple finishes like painting or laying flooring, while we handle the more technical elements.
Should I budget for unforeseen expenses?
Yes, it is recommended to allow a margin of 5 to 10% of the total budget. This allows for anticipating potential adjustments related to the terrain, urban planning, or additional work not initially planned.
