Apartment renovation in Luxembourg

Process of an apartment renovation

The technical visit allows us to validate the co-ownership constraints and establish a detailed estimate room by room. It is also at this stage that we identify any load-bearing walls and the steps to be taken with the property manager.

The work begins with the removal of the existing elements, followed by the updating of the networks if necessary. The technical aspects, plumbing, and electricity are always addressed before the finishes, to avoid having to reopen a freshly completed wall.

The coordination of trades is a particular challenge in collective buildings, where access to the site is more constrained than in individual houses. A precise schedule limits disturbances for the neighbors and shortens the overall duration of the work.

This step-by-step organization limits back-and-forth between trades and avoids the most common mistakes on this type of site: reworking a wall that is already finished, forgetting a duct passage, or finishing work done before plumbing tests are completed.

Service Areas in Luxembourg City

• Kirchberg: recent buildings, targeted renovations, and high-end finishes
• Gasperich and Ban de Gasperich: constructions from the last ten years
• Belair and Limpertsberg: older high-end buildings
• Bonnevoie and the train station area: small co-ownerships, studios, and family apartments

Co-ownership, VAT and administrative procedures

Work affecting common areas (technical columns, load-bearing walls, facade) requires the agreement of the property manager, usually voted on in a general assembly. We prepare the necessary technical documents to facilitate this validation, a step that can take several weeks depending on the co-ownership schedule.

For housing designated for residential use for more than ten years, the super-reduced VAT rate of 3% may apply to renovation work, within the limits set by the Registration Administration. We check the eligibility of your apartment during the technical visit.

Financing your renovation with public aid

Insulation work or the replacement of joinery, which falls under an energy renovation, may qualify for the Klimabonus scheme, which can be combined with the super-reduced VAT rate of 3% for properties over ten years old. Purely aesthetic renovations, on the other hand, are not covered by these schemes and remain subject to the normal VAT rate.

Have your apartment renovated in Luxembourg

A well-renovated apartment immediately stands out in the rental and real estate market of the capital, whether in Kirchberg, Belair, or more central neighborhoods. The technical visit remains the best starting point to accurately assess what needs to be done, even before discussing numbers.

Our teams coordinate all the necessary trades, including procedures with the property manager when required, for a project that progresses without unexpected administrative blockages. Whether you live in Kirchberg, Belair, or the train station area, one contact person remains responsible for your project from the first exchange to the final acceptance of the work.

Co-ownership and organization of the site in occupied housing

For strictly interior work that does not affect load-bearing walls, technical columns, or the exterior appearance of the building, no authorization from the co-ownership is generally required. However, as soon as a project modifies a common area (a technical shaft, a shared load-bearing wall, a window visible from the outside), the agreement of the property manager and sometimes a vote in the general assembly become necessary, a point identified during the technical visit to avoid any blockage during the project. Renovating an occupied apartment remains possible as long as the site is organized in successive zones rather than opening everything at once: a common solution for partial renovations, less obvious for a complete overhaul affecting plumbing and electricity, where it is often more comfortable to arrange temporary accommodation during the most extensive work.

Duration of work and aspects that enhance the property

Expect two to four weeks for light renovation, and two to four months for a complete renovation including the overhaul of networks; the duration also depends on the responsiveness of the co-ownership if authorizations are needed before starting the work. The kitchen and bathroom remain the areas that most influence the perception of a potential buyer or tenant. Enhanced sound insulation between apartments is also highly appreciated in collective buildings in the capital, where noise between neighbors remains a frequent source of frustration.
