Our installation team ensures a precise fit on site. Every part is inspected for accuracy and long-term durability.

Floating Stairs FAQs

Often yes, but it depends on your stair opening and required clearances. Floating stairs can be designed with different configurations (straight run, L-shape, U-shape) while still meeting code and comfort requirements.

It depends on your priorities:

  • Glass: best for uninterrupted views and a high-end modern aesthetic
  • Cable: best for an open look with a lighter feel and lower visual footprint
  • Metal: best for durability, design flexibility, and a wide range of styles
  • Mono stringer: One central steel spine supports the treads for a clean, minimalist look.
  • Double stringer: Two steel stringers (often on each side or spaced under the treads) for a more substantial, architectural feel and added rigidity.
  • Cantilever: Treads project from a wall/structural support with no visible stringer on the open side. This is the most “floating” look and typically requires specific structural conditions.

Floating stairs are open, modern staircases designed to look “light” and minimal, typically with open risers and a concealed or streamlined structural support (stringer). They create more visual space and allow more light to pass through.
