Home renovation work in Luxembourg

Process of a house renovation project

Our teams follow a structured method, from the initial diagnosis to the completion of the work. A single point of contact remains responsible for the project from the first meeting to the key handover, which avoids information loss between trades and unpleasant surprises during the project.

The first technical visit reviews the structure, roof, existing networks, and insulation level. It results in a detailed estimate, allowing us to prioritize the work according to your budget and the actual urgency of each intervention.

This is followed by the detailed design of the project and the selection of materials, then the actual preparation of the site: protecting unaffected areas, removing existing structures, securing networks. The work itself is coordinated by trade (masonry, electricity, plumbing, carpentry, finishing) to minimize downtime between each intervention.

The project handover includes a systematic check of each completed item, with the legal guarantees applicable to the work carried out in Luxembourg. Nothing is considered finished until you have approved the result.

Our intervention areas in Luxembourg City

We operate in all neighborhoods of the capital, with a good understanding of the specificities of each sector.

• Belair and Merl: villas and bourgeois houses from the mid-20th century
• Limpertsberg: mansions and high-end buildings
• Bonnevoie: older terraced houses, often in need of extensive renovation
• Kirchberg and Gasperich: more recent constructions, targeted renovations

This knowledge of local buildings allows us to anticipate the constraints specific to each neighborhood: access to the site in a dense city center, specific municipal regulations, or the particularities of the terraced houses in Bonnevoie.

Assistance and taxation for renovation in Luxembourg

Residential properties that have been used for habitation for more than ten years may benefit from a super-reduced VAT rate of 3% on renovation work, within a limit that will be revised in 2026. Items related to insulation or heating may also fall under the Klimabonus scheme, which combines state aid, energy supplier bonuses, and sometimes municipal subsidies. The precise conditions depend on the exact nature of the work: we verify them with you during the visit, and you can also consult the Guichet.lu portal for confirmation.

Any structural modification or alteration to the exterior appearance of the building remains subject to municipal authorization. For terraced houses, certain work also requires the agreement of the neighbor or the property manager if the property is in co-ownership. We integrate these procedures into the project planning.

Renovate your house in Luxembourg with Avenir Rénovations

A well-executed house renovation is evident in the ten years that follow: lower heating costs, less maintenance, a property that is easier to sell or rent. It is an investment that is calculated over time, not just based on the amount of the quote. You can estimate a rough figure with our online simulator, and then refine it with our teams during a free visit in Luxembourg City and the surrounding municipalities.

Whether your house is located in Belair, Limpertsberg, Bonnevoie, or in a more peripheral neighborhood, our teams are familiar with the specificities of local buildings and the administrative procedures specific to the City of Luxembourg. Each project is followed by the same contact person, from the first exchange to the handover of keys.
