Helical Staircases
Helical Staircases – flowing architecture and precision engineering
Helical staircases create a smooth, continuous connection between different levels. Their sweeping curves and open geometry make them a distinctive architectural feature and allow for generous, flowing circulation.
Siller Stairs designs and manufactures custom helical staircases for luxury residences, commercial buildings, hotels and architectural projects worldwide.
What Are Helical Staircases?
A helical staircase follows a continuous curve as it rises between floors. Unlike a traditional spiral staircase, it does not necessarily rotate around a central column.
The geometry, width, radius, materials and structural system can be individually developed to suit the architecture of each project.
Helical vs. Spiral Staircases
Spiral staircases typically wind around a central column and are designed for compact spaces. Helical staircases use a broader, flowing curve and create a more open architectural appearance.
Custom Helical Staircases
Siller develops each staircase individually, combining architectural design with precise structural engineering.
Custom helical staircases can incorporate:
- Wood and solid timber
- Glass and structural glass
- Steel and stainless steel
- Concrete and other architectural materials
- Frameless glass railings
- Integrated LED lighting
- Concealed structural systems
Double Helix Staircases
A double helix staircase consists of two intertwined helical staircases rising together. This complex geometry creates a striking architectural centerpiece and requires precise planning and engineering.
Helical Glass and Wood Staircases
Helical glass staircases combine flowing geometry with transparency. Glass can be used for treads, railings and, depending on the structural concept, load-bearing elements.
Helical wood staircases combine the warmth of natural timber with sculptural curves and concealed structural systems.
Structural Engineering for Helical Stairs
The visual lightness of a helical staircase depends on precise engineering. Geometry, loads, connections, supports and fixing systems are developed as part of the overall structural concept.
Siller works with architects, structural engineers and project partners to create custom helical staircases that combine design freedom with structural performance.
Helical Staircases for Residential and Commercial Architecture
Siller develops helical stairs for:
- Luxury homes and villas
- Penthouses
- Hotels and hospitality
- Offices and commercial buildings
- Showrooms and retail spaces
- Public and architectural projects
Helical Staircases FAQ
What is a helical staircase?
A helical staircase is a staircase that follows a continuous, sweeping curve between levels. Unlike a conventional spiral staircase, it does not necessarily require a central column.
What is the difference between helical and spiral stairs?
Spiral stairs typically wind around a central column and are suited to compact spaces. Helical stairs have a broader, continuous curve and offer a more open architectural appearance.
Can helical staircases be made from glass?
Yes. Glass can be used for treads, railings and, depending on the structural design, load-bearing elements. Frameless glass can further enhance the transparent appearance.
Can helical staircases be made from wood?
Yes. Wood is a popular material for helical staircases, offering a combination of natural warmth, durability and sculptural form. Timber can be combined with concealed steel structures.
What is a double helix staircase?
A double helix staircase consists of two intertwined helical staircases rising together. It is a highly architectural form that requires detailed geometric and structural planning.
Are helical staircases suitable for commercial buildings?
Yes. Custom helical staircases can be designed for residential, commercial and public architecture, with the structural requirements and applicable regulations evaluated for each project.
