Do you dream of a more spacious, bright, and pleasant interior? Removing a load-bearing wall can radically transform your space. But be careful, this is a delicate project that requires both technical expertise and adherence to certain administrative rules. Preliminary studies, budget, procedures, and implementation steps: discover everything you need to know before getting started.
What is a load-bearing wall and how to recognize it?
A load-bearing wall plays an essential role in the structure of your home. Unlike a simple partition, it supports the weight of the upper floors, the roof, or the framework. Removing it without caution can compromise the stability of your house.
Typical characteristics of a load-bearing wall
Several clues can help you identify a load-bearing wall:
- Thickness: in Belgium, a load-bearing wall is often wider than a standard partition, usually starting from 20 cm.
- Materials: concrete, stone, solid bricks, or concrete blocks are common for load-bearing walls, while partitions are often made of drywall or hollow bricks.
- Position: load-bearing walls are often perpendicular to the floor joists and may align over several floors.
Check the function of the wall
To be sure that a wall is load-bearing:
- Observe if it is continuous over one or more floors.
- Tap it: a load-bearing wall sounds "solid," while a partition sounds hollow.
- Consult a professional (architect or technical studies office - BET) to conduct a reliable structural study.
Administrative procedures before removal
In Belgium, removing a load-bearing wall constitutes a significant structural modification. The procedures vary depending on the region (Wallonia, Brussels, Flanders) and whether you are in a single-family home or a co-ownership.
Single-family home
If the opening modifies the structure or appearance, you will often need to submit a work declaration or request a building permit. Check with your municipality's urban planning department.
Co-ownership
For a load-bearing wall located in common areas (often in apartment buildings or terraced houses), the agreement of the property manager and a vote in the general assembly are necessary. The technical file must be complete: feasibility study, execution plans, and insurance.
Preliminary technical study
In all cases, a study by an architect or a BET is essential to assess feasibility and size the reinforcement. It is often required to obtain administrative authorization.
The cost of removing a load-bearing wall in Belgium
The budget depends on many factors: the opening to be created, the thickness and material of the wall, the floor, access to the site, the type of reinforcement needed (steel beam, concrete, or wood), etc.
Factors influencing the price
- Size of the opening (from a few centimeters to several meters).
- Material of the wall (concrete, stone, concrete block).
- Technical complexity (presence of electrical networks, plumbing, access difficulties).
- Type of reinforcement (steel I-beam, glued laminated timber beam, reinforced concrete).
Indicative estimates
- Preliminary study: ± 500 to 1,500 €.
- Permits and administrative fees: 200 to 800 €, depending on the municipality.
- Removal + reinforcement for an opening of 1 to 2 m: 3,000 to 6,000 € depending on complexity.
- Wide opening or complex project: up to 10,000 € or more.
- Structural reinforcement (steel, wood, or concrete beam): variable depending on dimensions and material.
Finishing work
After demolition and installation of the reinforcement, restoration will be needed: floors, ceilings, painting, and network repairs. Expect around 30 to 70 €/m² for these finishes, in addition to structural costs.
Technical steps for removal
- Study and load calculations: the architect or BET determines the weight to be supported and sizes the reinforcement.
- Installation of temporary supports: essential for securing the site.
- Installation of structural reinforcement: placing an appropriate beam or load-bearing element.
- Progressive demolition of the load-bearing wall: after securing, demolition step by step and removal of debris.
- Finishing: floors, ceilings, networks, plastering, painting, and cleaning.
