Interior fit-out in Liège

Materials & compatibilities: our recommendations (Belgian usage)

A lasting fit-out relies on compatible systems, easy to maintain and distributed in Belgium (reliable after-sales service).

• Partitions/false partitions: Gyproc/Fermacell on Metal Stud framework; moisture-resistant boards in wet areas; compatible bands & coatings.
• Joinery: solid core doors for acoustics, frames aligned, invisible hinges as an option.
• Storage: durable panels, clean edges, soft-close slides.
• Floors: engineered wood + acoustic underlay, LVT click flooring in living areas (stability), non-slip tiles in kitchen/bathroom.
• Paints: matte/velvet for walls, washable satin for circulation areas, suitable primer (Gyproc/plaster/existing paints).
• Lighting: compliant fixtures, appropriate IP in wet rooms, low-glare luminaires.

Common problems observed in Liège

We address the causes, not just the appearance.

• Dark & segmented spaces: adding skylights/glass doors, opening bays (if possible), rethinking the lighting plan.
• Insufficient storage: custom storage in under-slopes, entry furniture, optimized wardrobes (hanging spaces, drawers, columns).
• Impact noise & reverberations: resilient underlays, perimeter joints, selected absorbing materials.
• Cold walls: insulated false partitions, correction of thermal bridges, suitable finishes.
• Consistency of finishes: color palette, alignment corrections, harmonized baseboards and frames.

Urban planning procedures & co-ownership (Liège / Wallonia)

Most interior works (partitions, storage, doors, lighting, finishes) are exempt from urban planning procedures. However, modifications to the exterior appearance (facade, frames, dormers) or structural impact may require a Prior Urban Planning Declaration (DUP) or a Urban Planning Permit (PU) depending on the municipality. 

In co-ownership, certain areas (facade, shafts, circulation) are common parts: a syndic/AG vote is required. We prepare plans and a clear description to facilitate agreement.

Grants & taxation (Wallonia 2025-2026)

There is no regional grant for "fit-out" in the sense of decoration/pure redistribution. However:

• Energy/health items (interior insulation, ventilation) can be included in a global project eligible for Housing Grants (often through Housing audit; amounts adjusted by income categories R1→R5).
• Accessibility adaptations (PRM) sometimes benefit from local or specific aids; we check according to your municipality.
• For a private dwelling over 10 years old, the 6% VAT may apply to improvement/repair works (conditions).

We integrate these options without over-promising and plan the works to optimize the aids when they are available.

FAQ

Interior fit-out or "interior renovation": what’s the difference?

Fit-out focuses on volumes, storage, joinery, lighting, and finishes. Renovation more broadly includes technical lots (electricity RGIE, plumbing, heating/ventilation). We combine both if necessary for a coherent result.

Can I live on-site during the works?

Yes, with an appropriate phasing: protections for circulation, storage areas, maintaining key rooms (kitchen, bathroom) according to the schedule. We limit dust and clean at the end of each day.

Gyproc or Fermacell for my partitions?

Gyproc covers most configurations. Fermacell offers advantages in acoustics and mechanical resistance. We decide based on usage, budget, and room (standard, humid, highly used).

Are the glass partitions acoustic?

They let light through, but their acoustic performance depends on the glazing and joints. We offer enhanced solutions (laminated glass, adapted joints) if isolation is a priority.

Can I start with the finishes and do the storage later?

It’s better to do the opposite: layout plan → partitions/openings → storage → finishes. This avoids rework and ensures lasting coherence.
