Why choose Avenir Renovations?
Why renovate a residential or mixed-use building?
Renovating a building addresses technical, economic, ecological, and heritage challenges.
Improve energy performance
Old buildings are often energy-intensive. Through targeted work (insulation, joinery, ventilation, heating), you reduce consumption and improve the energy performance scores of the apartments, increasing their value and rental appeal.
Reorganize housing or uses
A building can be divided differently, expanded, or reconfigured: creating studios, adding a floor, transforming a commercial space into housing... All these operations allow for better utilization of every square meter.
Comply with standards
Electricity, fire safety, accessibility, ventilation: standards evolve. A renovation allows you to bring the building up to current Belgian standards, while anticipating future obligations.
Our services for building renovation
Avenir Rénovations offers a turnkey approach for all types of buildings: residential, mixed-use, rental, or intended for resale.
Essential work to renovate a building
As a renovation company, we help you assess priority interventions, measure energy impact, and prepare a file that you can present at the general assembly of co-owners. With Avenir Rénovations, you can develop a schedule or a multi-year plan for the renovation work of your building.
In a building, heat loss and noise disturbances can be significant. Insulating walls, floors, attics, or roofs helps reduce energy costs while enhancing occupant comfort. We use high-performance materials that comply with the energy performance standards in your region.
Poorly designed lighting or outdated windows harm energy efficiency and visual comfort. During renovations, we install LED lighting in common areas and replace old frames with modern joinery that has high thermal and acoustic performance. These improvements also enhance the building's aesthetic value.
Renovating a building is the perfect opportunity to review the collective heating system. Condensing boiler, smart regulation, switching to a modular system or decentralized production: we advise you on the most suitable solution for your building to combine energy savings and sustainable performance.
Facade renovation is both an aesthetic and technical operation. It protects the exterior walls from infiltration, frost, and cracks while giving the building a modern and well-kept appearance. Depending on the regions, this work may also benefit from financial assistance, especially when it includes external insulation.

FAQ: building renovation in Belgium
What status is needed to renovate a complete building?
It depends on whether it is a single ownership building (one owner) or a co-ownership. In single ownership, you freely decide on the schedule and budget. In co-ownership, the work must be voted on in a general assembly, according to the rules set by the property manager and the co-ownership regulations. We operate in both cases, with quotes tailored to each context.
Can a building be renovated while occupied?
Yes, but it requires rigorous organization: interventions by floor, time slots, protection of common areas, advance communication. We establish a detailed schedule, inform the occupants, and minimize disturbances as much as possible. A well-prepared renovation can perfectly take place with tenants on-site.
What are the value enhancement levers for an old building?
The main ones are:
- Energy renovation (improved energy performance = better profitability)
- Creation of additional or better-designed housing
- Aesthetics of common areas (immediate effect on value)
Regulatory compliance (more safety, less risk) We assist you in maximizing the potential of your building, with a combined technical and financial perspective.
