Interior renovation works in Luxembourg

What an interior renovation covers

• Demolition and redistribution of partitions
• Reworking of electricity and plumbing
• Installation of floor and wall coverings
• Complete renovation of the kitchen and bathroom
• Improvement of thermal and acoustic insulation

Process of an interior renovation project

The technical visit allows for defining priorities room by room and establishing a budget-consistent estimate. It is also the time to identify load-bearing walls that limit or allow certain space openings.

The construction site begins with demolition and preparation of supports, followed by the reworking of technical networks. Floor and wall coverings are installed last, once all technical aspects are validated.

Precise coordination between trades minimizes downtime between each intervention, a particularly important issue for projects combining multiple rooms at the same time.

Materials and finishes to prioritize

Floor coverings

Parquet, tiles, or laminate flooring: each material brings a different ambiance and a specific level of maintenance, to be chosen according to the room and daily traffic.

Wall coverings

Paint, wallpaper, or decorative coatings allow for personalizing each space while remaining coherent with the rest of the home.

Lighting and home automation

Well-thought-out lighting transforms the perception of an interior, and the integration of simple home automation solutions enhances daily comfort without excessive complexity.

Areas of intervention in Luxembourg City

• Merl: residential houses from the 1960s to 1980s
• Belair and Limpertsberg: high-end interiors to modernize
• Bonnevoie: more compact housing to optimize
• Kirchberg and Gasperich: recent apartments, high-end finishes

Regulations and Assistance in Luxembourg

The Merl houses built in the 1960s and 1970s often have electrical installations that no longer meet current standards. A complete upgrade is an integral part of our interventions whenever a renovation involves existing electricity, even partially.

Work that affects a load-bearing wall or modifies the structural distribution of the dwelling requires municipal authorization. We systematically check this point from the design phase, before any final costing.

For a dwelling over ten years old designated as the main residence, the super-reduced VAT of 3% can apply to all interior renovation work. Items related to insulation can also fall under the Klimabonus scheme.

Why Choose Avenir Rénovations for Your Interior Renovation

A Comprehensive Expertise Across All Trades

Our teams coordinate masonry, electricity, plumbing, carpentry, and finishing under a single point of contact, which avoids information loss between separate contractors.

Custom and Transparent Solutions

Each quote is detailed line by line, with no hidden fees discovered during the project, a transparency particularly appreciated in projects of this scale.

Clear Guarantees on Completed Work

Each intervention is covered by the legal guarantees applicable in Luxembourg, with follow-up after the work in case of questions or necessary adjustments.

Permits, Duration of the Work, and Living On-Site

A permit is not always necessary, except if the work affects a load-bearing wall or modifies the structure of the building; purely aesthetic or technical renovations generally do not require authorization. Expect two to four months for a complete interior renovation of an entire dwelling, depending on the number of rooms involved and the extent of technical work. Living in the dwelling during the work depends on the scale of the project: a renovation by room generally allows you to stay on-site, while a complete renovation affecting several rooms simultaneously often makes temporary accommodation more comfortable.

Sustainable Materials, Financing, and Current Trends

Natural materials and bio-based insulation are gaining popularity in Luxembourg, both for their environmental qualities and for their thermal and acoustic comfort in daily life. Regarding financing, several schemes can be mobilized depending on the situation: super-reduced VAT, Klimabonus for energy-related items, and, where applicable, favorable interest loans offered by certain Luxembourg banking institutions. Open and bright spaces, raw natural materials, and eco-renovation dominate current requests, with a growing interest in simple home automation solutions that do not overly complicate the daily use of the dwelling.

Whether your project concerns a house in Merl or a more central apartment, the same method applies: complete diagnosis before any estimate, precise planning of trades, and validation at each key stage of the site.
