Spiral Staircases
Spiral staircases – sculptural architecture in motion
Spiral staircases from Siller combine technical precision with architectural elegance and rank among the most expressive forms in modern staircase design. Whether crafted from wood, glass, or concrete — every spiral staircase is created to the highest standards of design quality, material selection, and craftsmanship.
The classic spiral staircase can be realized with a variety of tread materials, including glass, which gives the structure a distinctive lightness and transparency. The treads either follow the staircase’s circular path or are individually adapted to architectural conditions such as the contours of surrounding walls.
Alongside traditional designs with a central column of wood or stainless steel, Siller also develops innovative, minimalist concepts that reinterpret the structure through a pure design language.
One outstanding example is the SKY-SCREW spiral staircase, which dispenses entirely with visible steel elements. Depending on the version, the structure is made from glass, concrete, or wood and designed to create the visual effect of a rising rotor within the space — a dynamic sculpture uniting movement and architecture.
Concrete spiral staircases offer a particularly powerful form of architectural expression. Concrete gives a space stability, calm, and a distinctive presence. Used deliberately as a design element, it creates an atmosphere of permanence and modern clarity.
Wood spiral staircases, by contrast, emphasize the material’s natural qualities. They convey warmth, authenticity, and an organic connection to the architecture. Wood remains a central element of staircase design, revealing its timeless appeal in both classic and modern interiors.
The result is spiral staircases that go far beyond their functional purpose — architectural objects that unite space, movement, and material in a sculptural whole.
