SPIRWILL EXT: modular aluminium structure for outdoor use

A modular outdoor staircase for terraces, balconies and gardens

SPIRWILL EXT is a straight or turning outdoor staircase built from lightweight aluminium modules. It provides an easy link between terrace, balcony, garden or upper level without visually overloading the façade. Its clean, graphic lines suit contemporary architecture as well as renovation projects that need a discreet yet comfortable exterior access.

Lightweight, safe and tailored to your project

The combination of aluminium structure and stainless steel handrail keeps SPIRWILL EXT both light and stable. Thanks to its modular design, the staircase can be configured with a landing, turning steps or a short run of steps to match the available space. The result is an outdoor staircase that fits the layout of your property and the way you use it every day.

Why choose the SPIRWILL EXT staircase?

Modular aluminium structure

SPIRWILL EXT is built from aluminium profiles assembled into modules. This approach reduces the weight on the foundations and simplifies handling on site, even where access is limited. Aluminium naturally resists corrosion, making the staircase suitable for exposed façades, damp gardens or areas close to a pool.

Anti-slip steps in recycled plastic

The steps are made from dense recycled plastic with an anti-slip surface. They do not rot, do not splinter and need only minimal maintenance.
Key advantages of these steps:

  • secure footing, even in wet conditions;

  • environmentally conscious use of recycled material;

  • no painting, oiling or sanding required.

Exterior staircase with a vintage design signature

The design of SPIRWILL EXT is inspired by the vintage work of Willy Van der Meeren, giving the staircase a distinctive architectural character. The slim structure gently frames the façade instead of hiding it. It pairs easily with other outdoor arrangements such as terraces, balustrades or garden structures to create a coherent overall look.

Versatile uses around the house or building

This staircase is suitable for many configurations:

  • main or secondary access to a raised terrace;

  • connection between balcony and garden level;

  • exterior access to an office, studio or guest room;

  • a few outside steps to overcome a change in level.
    With its modular components, SPIRWILL EXT can be adapted in length, direction and slope so it fits comfortably into narrow façades as well as more generous outdoor areas.

Safety, handrail and everyday comfort

The stainless steel handrail offers a reliable grip along the full flight. Matching balustrades can be added on one or both sides, using slender posts that keep views open. Step height and depth are designed for a natural walking rhythm, which is essential for frequently used exterior access routes in family homes or professional premises.

Quick installation, controlled budget and clear documentation

Because of its modular construction, SPIRWILL EXT is largely pre-assembled in the workshop and then installed on site in a straightforward sequence. This limits installation time and helps keep the overall cost under control while still delivering a made-to-measure outdoor staircase. A detailed technical sheet and assembly manual are available to support contractors, designers and architects throughout the project.
