Siller Stairs

Custom architectural stair systems are designed to function not only as circulation elements but also as defining spatial features, and Siller Stairs by Siller Treppen represent this approach through a wide range of highly engineered, bespoke staircase solutions. The brand specializes in creating unique stair designs that combine advanced structural engineering with refined material expression, resulting in staircases that often become the focal point of a project.

Siller Treppen develops multiple staircase typologies, including glass stairs, wooden stairs, cantilever systems, helical forms, and hybrid material compositions. These systems are tailored to each project, allowing flexibility in geometry, structure, and finish. Whether designed as a fully transparent glass stair or a sculptural wooden structure, each product is engineered to achieve both structural performance and visual lightness.

A key characteristic of Siller Stairs is the integration of minimal structural solutions. Many of their designs eliminate visible supports, creating floating or freestanding effects that enhance spatial openness. This approach requires precise engineering and fabrication techniques to ensure safety while maintaining a clean architectural expression.

Material diversity plays a central role in the system. Glass is often used for transparency and light transmission, while wood introduces warmth and tactility. Steel and stainless steel elements are incorporated where necessary to provide structural reinforcement or detailing. This combination allows the stair to adapt to a variety of architectural contexts, from residential interiors to public and cultural spaces.

Siller Stairs ultimately represent a fusion of craftsmanship, engineering, and design, offering architects a highly flexible system to create iconic and functional stair elements within contemporary architecture.
