Why replace or install a new staircase?
A poorly placed, too steep, or poorly lit staircase can quickly become an everyday discomfort, even a danger. Changing it also means .
Adapting the staircase to your needs
Are you renovating your attic? Transforming a duplex? Creating a mezzanine or a finished basement? A new staircase is essential to facilitate circulation and ensure safety.
Improving safety and compliance
Old staircases do not always meet current standards: irregular steps, lack of handrails, too steep a slope... Installing a new staircase allows you to ensure stability, ease of use, and safety for children or the elderly.
Modernizing aesthetics
A solid wood, metal, glass, or suspended staircase can become a true decorative asset. It is also a way to modernize an old house or give character to a somewhat empty room.

FAQ: Installing a staircase in Belgium
Do I need a permit to install a new staircase?
Generally, no, unless the staircase alters the exterior appearance of the house (facade opening, roof modification for a well, etc.). Indoors, adding or replacing a staircase does not require a building permit, as long as the exterior structure remains unchanged. However, if the staircase leads to an independent dwelling (studio, self-contained floor), a declaration may be required. Avenir Rénovations checks the legal obligations based on your municipality and assists you with the necessary procedures.
What are the criteria for a comfortable and safe staircase?
A good staircase meets several parameters: sufficient tread (at least 24 cm), regular step height (17 to 19 cm), suitable incline (30 to 40°), presence of solid handrails, good ground grip, adequate lighting. These standards ensure smooth and safe use, especially for children and seniors. We also adapt the choice of material (warm wood, stable metal, non-slip...) to maximize comfort and durability.
Can I combine the staircase with integrated storage?
Yes, this is a highly appreciated option. The space under the staircase can accommodate cabinets, shelves, drawers, or even a workspace. This allows you to make the most of lost space and create a layout that is both practical and stylish. Our carpenters design the integrated furniture in harmony with the staircase style for a cohesive and durable finish.
