Why choose Avenir Renovations?
The diagnostic phase: The audit and the structure
Thermal and structural analysis of the building
Before taking out the first tool on site, it is essential to understand the structure of your property. Many old buildings in Marche have thick but poorly insulated walls. A comprehensive renovation almost always begins with a rigorous thermal and structural analysis.
Housing Audit and Walloon grants
The PEB (Energy Performance of Buildings) is at the heart of any consideration. We help you identify priorities: is it the roof that is letting heat escape? Humid walls that need treatment before finishing? In Wallonia, going through a Housing Audit is often the key to unlocking substantial grants. We support you in this process to optimize your renovation insulation budget.
Foundation stabilization and opening up
On the structural side, our masons intervene to stabilize the foundations if necessary or to create openings. As part of an opening up, the installation of metal beams (type HEA or IPN) allows for the creation of large living spaces. These operations are carried out with precision to ensure the long-term stability of the whole.
Project steps
Every house renovation in Marche-en-Famenne follows the same guiding principle: diagnose before acting, plan rigorously, control at every stage. Here is how we proceed concretely.
Reinventing living spaces: Kitchen and living room
It is inside that the transformation makes the most sense. The ground floor is often the stage for the most significant changes. We reshape the volumes, integrate suitable lighting, and take care of the wall finishes.
Whether you prefer an industrial style with exposed bricks or a minimalist finish with perfect coatings, our plasterers and painters ensure a clean result. You can check our specific services for the renovation of your living room for more details on our techniques.
The true heart of the modern home is the kitchen. We design it as a hybrid, functional, and friendly space. We manage all plumbing (Alpex pipes) and electricity (RGIE standards) to accommodate your new appliances. Whether it's installing a central island or maximizing storage in a village kitchen, every detail is thought out for your daily use.

Note: In Wallonia, certain energy works (insulation, ventilation, high-performance heating, frames) can be included in a renovation pathway with audit and grants (often adjusted by income category and performance achieved). In Marche-en-Famenne, it is wise to plan the steps to maximize the cost / energy gain ratio.
Energy performance and joinery: The thermal shield
Replacement of frames and glazing
Once the structure is validated, we tackle the envelope. In Marche-en-Famenne, the wind can be sharp. Replacing old frames is often the most profitable investment in the short term. We install joinery in PVC, aluminum, or wood, equipped with high-performance glazing, which eliminates drafts and reduces heating bills.
Insulation of attics and walls
Insulation does not stop at windows. We insulate your attics and, depending on the configuration, your walls from the outside (render on insulation) or from the inside via partition walls. A well-insulated building also means increased comfort in summer, preventing overheating during the heatwaves that are now recurrent in our region.
The night zone and well-being: Bedrooms and bathrooms
Bedrooms: acoustic comfort and storage
Upstairs, priorities change. The renovation of your bedroom should prioritize acoustic insulation, especially if you live near a busy road in Marche. We install soundproof partitions and warm flooring. Custom wardrobes help free up visual space.
Bathroom: waterproofing and careful finishes
The bathroom becomes your personal relaxation space. Room for the Italian shower, completely waterproof thanks to Kerdi waterproofing mats. From the choice of large-format tiles to the installation of thermostatic faucets, every detail matters. Once the work is completed, a simple pass of the squeegee on your glass walls keeps your bathroom spotless.
A rigorous site management
A single point of contact to coordinate trades
One of the most common obstacles to renovation is the coordination of trades. By choosing Avenir Rénovations in Marche-en-Famenne, you only have one point of contact: the Avenir Rénovations team. They plan each intervention, ensure that materials are delivered on time, and that teams follow best practices.
6% VAT and tax benefits
The reduced VAT of 6% applies to all work — materials and labor — in any Walloon home over ten years old. This is a substantial saving that sometimes allows for more refined finishes, such as a beautiful design handle or a contemporary switch.
Cleanliness and restoration at the end of the site
Our teams ensure daily cleaning of the site and use industrial vacuum cleaners to limit fine dust. Upon handing over the keys, you only need to unpack your boxes.
Why choose us for your project in Marche?
A local presence and knowledge of the area
Our local presence is our main asset. We are not an outside company to the region. Based in Marche-en-Famenne, we also operate in Rochefort, Ciney, Hotton, Nassogne, and Durbuy. We know the Walloon urban planning regulations (the CoDT) and maintain good relationships with municipal services.
The same rigor for every project
Renovating a house means giving it a second life. Whether you need a major renovation including structural work and roofing, or a targeted aesthetic refresh focused on painting and flooring, we bring the same rigor to every project.
Common issues and our solutions
Persistent humidity in old walls
Houses made of limestone rubble in the Marche-en-Famenne region, particularly in Waha or Hargimont, often face rising damp or difficult-to-diagnose lateral infiltrations. Before any interior finishing, we conduct a complete humidity diagnosis to identify the exact source — whether it is a peripheral drainage defect, a degraded facade joint, or a lack of damp-proofing. The treatment is then targeted: resin injection, remedial coating, or restoration of external drainage as needed.
Removing partitions without prior stability study
Opening a wall to create an open living space is tempting, but some partitions are load-bearing — and their removal without structural calculations can compromise the stability of the entire floor. We do not begin any partition removal without precisely determining the structural role of the wall in question, consulting an engineering office if necessary. The installation of a properly sized HEA or IPN beam then ensures a durable load transfer without differential settlement.
Renovation in an occupied house: daily management
Renovating a house while continuing to live in it is possible, but it requires rigorous organization to maintain the comfort of the occupants. Our local artisans establish a precise phasing from the start: the rooms out of service are treated first, plastic protections isolate the living areas, and dusty work is carried out outside peak hours. We aim to maintain access to the kitchen and a functional bathroom at all times.
Frequently Asked Questions
How long does a complete renovation project take in Marche-en-Famenne?
The duration depends on the scope of the work and the size of the property. A comprehensive renovation project — structural work, carpentry, electricity, plumbing, and finishing — generally lasts several weeks to a few months. Our specialists create a detailed schedule from the design phase so you have a clear view of the steps and timelines.
Can we benefit from the 6% VAT on all work?
Yes, for a property over 10 years old, this reduced rate of 6% applies to all renovation work carried out by a professional. This is a substantial saving that can allow for more refined finishes or to expand the scope of the project without exceeding the initial budget.
How does the Housing Audit work and how does it help obtain grants?
The Housing Audit is a thermal and structural analysis of your property conducted by a certified auditor in Wallonia. It identifies intervention priorities and opens access to substantial grants related to energy performance. At Avenir Rénovations, we assist you in this process to optimize your renovation budget.
What work should be prioritized during a renovation?
The logical order starts with the structure and envelope: foundations, roofing, frames, and insulation. These elements determine the durability of everything else. Next comes bringing electrical and plumbing installations up to standard, before tackling interior fit-outs and finishes.
Is it possible to continue living in your house during the work?
This depends on the scale of the project. For light renovations or room-by-room work, it is often feasible to stay on-site. For major renovations involving structural work or complete stripping of living spaces, temporary accommodation is generally recommended. Our site manager assesses this feasibility with you from the diagnostic visit.
