Why choose a masonry brick extension?
Before embarking on concrete steps, it is essential to understand why masonry brick remains a reference choice for enlarging a house in Switzerland. This material combines robustness, durability, and aesthetics, while meeting local energy and architectural standards.
Masonry brick offers excellent thermal inertia, natural humidity regulation, and great longevity. It limits the risks of condensation, improves indoor air quality, and provides appreciable sound insulation. Aesthetically, it harmoniously integrates with existing facades while enhancing the property value.
In urban areas as well as in rural zones, brick adapts to a wide variety of architectural styles. It can be combined with modern materials like glass or steel for a contemporary look while remaining warm. This versatility allows for the design of a custom extension that is perfectly coherent with your house.
Key steps in the brick masonry extension project
Here is a clear and structured overview of the main steps to follow to successfully complete your brick masonry extension project, from the initial design to the turnkey delivery.
Possible designs for a brick extension
The possible configurations vary according to your land, your current house, and your goals:
This configuration involves directly enlarging the existing rooms by extending the house to the side. It is ideal for a living room, kitchen, or additional bedroom on the ground floor.
This is a brick construction detached from the main house but located nearby, connected or not. Perfect for creating an office, workshop, or habitable outbuilding without modifying the existing structure.
This option allows you to add a floor to your house without encroaching on the land. It is particularly useful in urban areas where ground space is limited.

FAQ (to be inserted just before the conclusion)
What are the approximate timelines for a 20 m² brick home extension?
Depending on the complexity, administrative response, or local requirements, the construction usually lasts from 2 to 4 months, excluding procedures.
Is an architect always required for an extension in Switzerland?
In Switzerland, thresholds vary by canton. Generally, any extension exceeding 150 m² or structurally altering the facade requires a professional. You must consult the local authority.
Is brick masonry compatible with high-performance insulation?
Yes. Even though it offers good natural thermal inertia, it is systematically complemented by high-performance insulation (RT 2012 or Swiss Minergie or ECO standard).
Can you live in the house during the work?
Yes, in most cases. The attached lateral extension allows you to continue occupying the house during the construction. In the case of a storey addition, a temporary reorganization is preferable.
What impact does the brick extension have on the property's value?
Brick adds significant value: durable material, classic aesthetics, energy performance. The return on investment is often higher than the initial cost.
