Timber brings to the staircase a warmth, tactility, and material depth that no manufactured surface can fully replicate. Siller Treppen's wood stair systems begin with the selection of the timber itself — a choice that defines the character of the finished staircase as much as the form. From the fine grain of European oak to the dramatic figure of American walnut, the open pore of ash, or the dense closeness of beech, each species offers a distinct visual and haptic register that interacts with the surrounding interior in its own way.
Siller's timber treads are produced from solid or engineered wood depending on the structural and dimensional requirements of the project, and finished with natural oils, hard-wax treatments, or lacquers in the full range of RAL and NCS tones. Custom staining extends the palette beyond natural species colours, allowing treads to integrate with or deliberately contrast against floor and joinery finishes. Timber treads are most commonly combined with glass or steel balustrade systems in Siller's range, pairing the warmth of wood with the lightness of transparent or minimal guardrail configurations.
Wood stairs are the single most widely specified stair typology in private residential architecture, and Siller's custom approach ensures that even a timber tread can be a bespoke design decision rather than a standard selection. They are equally at home in high-end residential apartments, boutique hotels, Scandinavian-influenced commercial interiors, and any project where the material palette prioritises natural, tactile warmth over industrial finish.
