Spiral Stairs
What are Spiral Stairs?
Spiral stairs are stairs that wind around a central column or support, creating a compact, circular form. Their space-efficient design makes them ideal for connecting different levels where floor space is limited.
With their distinctive shape, spiral stairs can also serve as a strong architectural feature in residential and commercial spaces.
Spiral Stairs vs. Helical Stairs
Spiral stairs wind around a central column or support, creating a compact, circular design. Their space-efficient geometry makes them an ideal solution where floor space is limited.
Helical stairs follow a smooth, continuous curve without a central column. Their open, flowing design offers greater freedom in terms of shape, width and architectural integration.
In short: Spiral stairs provide a compact, space-saving solution, while helical stairs offer an open, sweeping architectural form.
Spiral stairs – sculptural architecture in motion
Spiral stairs from Siller combine technical precision with architectural elegance and are among the most expressive forms in modern staircase construction. Whether made of wood, glass or concrete - every spiral staircase is created with the highest standards of design quality, choice of materials and craftsmanship.
The classic spiral staircase can be realized with different step materials, including glass steps, which give the construction a special lightness and transparency. The steps either follow the round course of the staircase movement or are individually adapted to architectural conditions such as wall courses.
In addition to traditional designs with a central spiral made of wood or stainless steel, Siller also develops innovative, reduced concepts in which the construction is reinterpreted in its pure design language.
An outstanding example is the SKY-SCREW spiral staircase, which completely dispenses with visible steel elements. Depending on the version, the construction is made of glass, concrete or wood and is designed in such a way that the visual effect of a rising rotor in the room is created - a dynamic sculpture made of movement and architecture.
Spiral stairs made of concrete open up a particularly powerful, architectural form of expression. The material concrete gives the room stability, calm and a strong presence. As a consciously used design element, it creates an atmosphere of stability and modern clarity.
Wooden spiral stairs, on the other hand, emphasize the natural side of the material. They convey warmth, originality and an organic connection to architecture. Wood remains a central element in stair construction and develops its timeless effect in both classic and modern room concepts.
This is how spiral stairs are created that go far beyond their functional task - as architectural objects that combine space, movement and material into a sculptural unity.
