Floating staircases achieve their defining visual effect through the strategic concealment of structure: treads appear to project from the wall with no visible means of support, creating an open, gravity-defying composition that transforms a functional element into a design statement. Siller Treppen's floating stair systems are engineered around a concealed steel spine or wall-embedded bracket system, which transfers all loads into the building's structural wall while leaving the tread surfaces entirely unencumbered — no riser, no soffit, no apron.
The precision required to deliver a convincing floating staircase is significant. Each tread is individually anchored, its bracket concealed within the wall finish, and the reveal between tread and wall is controlled to millimetre tolerances to maintain the illusion of suspension. Tread materials span the full range of Siller's offering — solid oak, walnut, stone, glass, or lacquered steel — and each is profiled to eliminate any visual cue of the fixing below. Open risers allow light and sight-lines to pass through the staircase, further reinforcing the sense of weightlessness.
Floating staircases are among the most frequently specified stair typologies in contemporary residential architecture, where open-plan interiors demand circulation elements that preserve spatial continuity rather than interrupting it. They are equally effective in commercial showrooms, boutique retail environments, and hospitality projects where the staircase is intended to communicate lightness, modernity, and material refinement.
