Why choose Avenir Renovations?
Why renovate your apartment in Liège?
Renovating is primarily about better living every day: smooth circulation, integrated storage, better distributed light, and improved acoustics. It is also about securing the technical base (electricity to RGIE, healthy plumbing, suitable ventilation) and enhancing the property in a demanding rental and resale market.
In the province of Liège, many apartments built before the 2000s have room for improvement: poorly insulated partitions, old frames, networks to be updated, dated bathrooms. We prioritize what has the most impact: intelligent redistribution, kitchen/bathroom, ventilation, thermal and acoustic improvements compatible with the co-ownership.
Working method: your project in 5 steps
A clear process reassures the co-ownership and occupants, limits rework, and secures deadlines. We formalize each milestone with simple documents and regular progress updates.
Our services for apartment renovation
Each project starts with a technical visit: measurements, photos, identification of columns/shafts, access constraints and usage expectations. We propose prioritized scenarios, explain the technical and budgetary implications, and then phase to limit disturbances when the residence remains occupied. The items below can be priced individually or included in a turnkey package.
- Creation/removal of light partitions (Gyproc/Fermacell), optimization of circulation, integration of storage.
- False ceilings for spots and networks; light gain via skylights/pass-throughs when relevant (after structural verification).
- Compliance with acoustic requirements between night and day rooms.
- Redesign of plumbing/drainage, ergonomic layout, SPEC (waterproofing under tiles), walk-in showers.
- Appropriate lighting (general + work surface), built-in appliances, durable and easy-to-maintain finishes.
- Dedicated ventilation (timed/hygro extraction) to maintain air quality.
- Compliance with RGIE: panel, differential switches, dedicated circuits (kitchen, bathroom, heat pump/boiler), certificate of conformity.
- Heating: suitable radiators or underfloor heating if the structure allows; zonal regulation/thermostats.
- Ventilation: effective extractions in wet rooms, decentralized solutions if necessary, flow adjustments.
- Resilient underlays under floors, acoustic screeds, disconnected false ceilings.
- High-density linings on targeted party walls, treatment of connections (peripheries, boxes, penetrations) against acoustic bridges.
- Thin solutions preferred to limit loss of surface area.
- Installation of tiles, parquet (solid/engineered) or LVT/SPC, leveling if necessary.
- Paints matte/velvet/satin depending on the room, paintable non-woven, vinyl wallpapers in wet areas.
- Interior carpentry: doors, frames and baseboards; custom fittings (closets, libraries).
- Preparation of a clear file for the property manager/AG (plans, description, schedule, anti-nuisance measures).
- Protection of common areas, management of deliveries and evacuations, respected time slots.
- Uniformity of facade in case of visible frames (shades/imposed divisions).
Price of an apartment renovation in Liège (including VAT)
Budgets depend on the area, initial condition, level of finish, and co-ownership constraints (access, protections, hours). A detailed quote always follows a technical visit. The ranges below serve as benchmarks for the province of Liège.
| Item | Price indication (including VAT) |
| Turnkey renovation (excluding furniture), per m² | 900 to 1,600 €/m² |
| Complete kitchen (excluding premium appliances) | 8,000 to 18,000 € |

| Bringing an apartment up to RGIE standards | 2,500 to 6,000 € |
| Partitions + false ceilings (installation + finishing), per m² | 45 to 90 €/m² |
| Laminate/vinyl flooring (supply + installation), per m² | 35 to 85 €/m² |
| Engineered wood flooring (supply + installation), per m² | 55 to 120 €/m² |
| Tiling (supply + installation), per m² | 50 to 120 €/m² |
| Interior painting (preparation + 2 coats), per m² | 12 to 25 €/m² |
| Targeted acoustic treatment (insulation/ceiling), per m² | 60 to 140 €/m² |
Budget tip: if necessary, we phase to quickly deliver the key benefits (RGIE safety, kitchen/bathroom, circulation), while postponing certain decorative finishes without losing coherence.
Urban planning, co-ownership & compliance (Liège / Wallonia)
Interior work without visible impact from the street and without major structural modification is often exempt from procedures. On the other hand, load-bearing openings, visible frame changes, modification of openings or ETICS fall under a DUP or a PU depending on the municipality and visibility.
In co-ownership, the facade is generally common: syndic/AG decisions, colors, and divisions may be required. We prepare the documents (plans, description, colors, schedule), coordinate validations, and ensure RGIE compliance and suitable ventilation.
Why choose Avenir Rénovations Liège?
Renovating an apartment requires method, pedagogy, and precision. We combine coordination, quality of installation, and respect for the premises to deliver a uniform and durable result, without overloading the occupants with constraints.
- Turnkey: a single point of contact, management of orders, schedules, and communication with the co-ownership.
- Controlled quality: check-lists RGIE/SPEC/ventilation, progress photos, partial receptions if needed.
- Transparency: quotes by lots, clear variations, phased calendar.
- Respect for common areas: protections, signage, adapted time slots, clean evacuation.
- After-sales service: adjustments, touch-ups, and maintenance advice after reception.
Frequently Asked Questions
Before getting started, you may have questions about living with the construction, the duration, permits, acoustics, or ventilation. This FAQ gathers operational answers tailored to the Liège context (co-ownership, city center, access).
Can we live in the apartment during the works?
In most cases, yes. We phase the construction to free up living spaces each evening, set up protection (floors, pathways, dust confinement), and schedule noisy tasks during the day. In case of work on the kitchen/bathroom, we organize temporary solutions and tight planning to minimize discomfort.
Is it feasible to open the kitchen to the living room in an apartment?
Often yes, subject to structure, ducts, and co-ownership approval. We check if the partition is load-bearing (IPN/HEB if necessary), anticipate extraction/electricity/water needs, and prepare a file for the property manager/AG if the facade or common columns are affected. Phasing avoids prolonged service interruptions.
How to improve acoustics without losing too much square footage?
We combine resilient underlays under floors, decoupled false ceilings, high-density linings on targeted walls, and treatment of connections (peripheries, boxes, penetrations). There are thin systems available to preserve surface area. The initial diagnosis guides the most effective mix according to your building.
RGIE, ventilation, PEB: where to start?
First, we secure the technical base: electricity according to RGIE (panel, differential switches, circuits), properly sized ventilation (effective extractions), and sound plumbing. Then, we address the wet rooms and acoustics, followed by finishes (floors/paints). For the PEB, we document materials and proof of implementation so that the gains are recognized.
What permits are required in Liège?
Purely interior works generally do not require a permit. However, modifying the external appearance (visible openings/frames) or the structure requires a DUP or a PU depending on the case; in co-ownership, the agreement of the property manager/AG is essential. We prepare the necessary documents (plans, descriptions, colors, photos) and ensure compliance with the building regulations.
How long for a “standard” renovation of 70–90 m²?
As a guideline, expect 6 to 10 weeks for light redistribution, kitchen/bathroom, floors, and paints, excluding specific supply delays (frames, kitchen). In the presence of strong constraints (city center, co-ownership), we plan clear milestones and regular communication.
