Why expand your home with a garage in Luxembourg
Creating an attached garage allows you to meet multiple needs, whether functional or aesthetic. In Luxembourg, where the climate sometimes imposes demanding conditions, having a closed space to shelter your vehicle and store equipment is an undeniable advantage.
A secure space for your vehicle
Having a garage attached to your home guarantees protection for your vehicle from the elements and theft risks. This extension becomes a versatile space, ideal for storing bikes, tools, or seasonal equipment. Moreover, it provides direct access to the house, particularly appreciated in winter.
A true asset for the value of your property
The addition of a garage increases the usable area of your home and enhances your real estate value. In case of resale, a well-integrated and properly insulated extension attracts buyers and justifies a higher selling price in the Luxembourg market.
Everyday comfort
Besides parking, an attached garage can accommodate a laundry room, a workshop, or an additional storage room. The extension then becomes a multifunctional space, perfectly suited to the evolving needs of families.
Steps of a house extension project with garage in Luxembourg
A project for an extension is not improvised: it requires rigorous planning and professional support. At Avenir Rénovations Luxembourg, every step is mastered to ensure a reliable and aesthetic result.
The different types of extensions with garage in Luxembourg
Depending on your needs and the style of your home, Avenir Rénovations Luxembourg offers several configurations of extensions with garage. The choice will depend on your land, municipal regulations, and your budget.
The side extension involves adding the garage to one side of the existing building. This solution, very common in Luxembourg, integrates harmoniously with the facade while maintaining direct access from the house. It is perfectly suited for plots with free lateral space.
Building the garage at the front of the house is an interesting option when the configuration of the land does not allow for expansion on the sides. This type of project requires particular attention to the aesthetics of the facade and compliance with urban alignments.
Ideal for sloping plots, this solution allows for the creation of a semi-buried garage under a home extension. It preserves the ground surface while adding a functional and aesthetic volume, perfectly integrated into the topography of the land.

Which materials to choose for your extension with garage
The choice of materials directly affects the visual appearance, thermal performance, and durability of your extension. Avenir Rénovations Luxembourg advises you on harmonizing the new volume with your existing structure.
The concrete extension
Concrete offers excellent resistance and optimal insulation. Its sober and modern aesthetic fits well with contemporary constructions. Moreover, it allows great freedom of shapes and finishes for a perfectly integrated garage.
The brick or stone extension
These traditional materials ensure perfect integration into the Luxembourg architectural landscape. Brick and stone provide robustness, insulation, and timeless charm while respecting local aesthetic codes.
The timber frame extension
Wood, lightweight and eco-friendly, allows for quick and energy-efficient construction. Highly valued in Luxembourg, it offers excellent natural insulation and a warm appearance, ideal for a garage attached to a modern or traditional house.

Regulations for a house extension with garage in Luxembourg
Before undertaking an extension with a garage, it is essential to know the applicable local regulations. Each Luxembourg municipality has its own urban planning rules, whether regarding distances to be respected, permitted heights, or accepted materials. Avenir Rénovations Luxembourg supports you at every step to ensure your project's compliance.
Permits and administrative procedures
Any house extension, whether attached or independent, requires a building permit issued by the municipality. The file generally includes architectural plans, a technical notice, a description of materials, and energy compliance. Avenir Rénovations takes care of compiling and submitting your complete file to the municipal services.
Distances and property boundaries
The distance rules to be respected depend on the General Development Plan (PAG) of each municipality. In general, a minimum setback of 3 to 5 meters from the property line is required. This distance may vary depending on topography, roadways, or the nature of the land.
Height and footprint
The extension with garage must not exceed the heights set for the existing building. The added surfaces are included in the calculation of the gross floor area (GFA), subject to taxation and local urban planning rules. Municipal services may impose a maximum height to preserve the architectural harmony of the neighborhood.
Access and safety
A garage must be easily accessible from the public road while respecting road safety and visibility standards. The gate, lighting, and access slope are designed to ensure comfort and compliance. If the garage includes an electrical installation, it must meet the current Luxembourg standards (ILNAS, Grand-Ducal regulation of December 14, 2017).
Insulation and energy performance
Any extension must comply with the energy requirements defined by the Grand-Ducal regulation of November 30, 2007, on the energy performance of buildings. This includes thermal insulation of walls, the U-value of openings, and airtightness. Avenir Rénovations Luxembourg ensures that your attached garage positively contributes to the energy efficiency of your home.
Options and additional fit-outs for your garage
A garage can be much more than just a parking space. With thoughtful design, it can become a multifunctional, aesthetic, and pleasant place to use.
Motorized garage door
Motorization offers unmatched convenience, especially during bad weather. Current automated systems ensure smooth, quiet, and secure opening while integrating with your home automation.
Insulation and integrated heating
For an attached garage, effective insulation helps prevent thermal losses. It is also possible to add a small auxiliary heater or an insulated floor to make the space more comfortable, especially if you use it as a workshop.
Windows and natural lighting
Incorporating glazed openings allows natural light into your garage, making it more pleasant to use. However, these openings must be secured and comply with waterproofing standards.
Storage and organization
Wall shelves, custom cabinets, or bike racks help optimize space without obstructing movement. Avenir Rénovations Luxembourg can offer you custom fit-outs tailored to your habits and needs.
FAQ on home extension with garage in Luxembourg
Is a building permit required for an extension with garage in Luxembourg?
Yes, the construction of an attached or independent garage requires a building permit issued by the municipality. The application includes architectural plans and a complete project description. Avenir Rénovations Luxembourg handles this process for you.
What type of garage to choose: attached or independent?
The choice depends on your land, budget, and needs. An attached garage optimizes access and limits thermal losses, while an independent garage allows for more architectural freedom and sound insulation.
How long does it take to build an attached garage?
On average, it takes between 2 and 4 months for a complete project, from site preparation to finishing touches. This timeframe varies depending on weather conditions, the complexity of the structure, and the speed of obtaining the building permit.
Can a room be added above the garage?
Yes, it is entirely possible to create a room above the garage, such as a bedroom, office, or studio. This solution optimizes living space while maintaining a controlled footprint. However, it requires prior structural assessment.
What is the average cost of an extension with garage in Luxembourg?
The price depends on the type of materials, surface area, and level of finish. Generally, you should budget between 25,000 and 60,000 CHF for a standard attached garage, including foundations, insulation, finishes, and roofing.
Does the garage need to be insulated like a living space?
Not necessarily, unless you plan to create a heated room there. However, minimal insulation is recommended to limit thermal losses and avoid temperature fluctuations in the adjoining house.
