Architectural Elegance for Grand Interiors

A helical staircase is more than a feature, it’s an architectural statement. Perfect for large, open-plan spaces and prestige properties, Kallisto’s precast concrete helical staircases combine sweeping curves with structural precision to create a stunning focal point that elevates any interior.

Personalise your stair with bespoke balustrades, luxurious surface finishes, and a design tailored entirely to your vision. With a sculptural, elliptical form and seamless structure, our helical stairs leave a lasting impression in both private residences and commercial spaces.

What is a Helical Staircase?

A helical staircase, also known as a curved stair, forms a continuous spiral or “C” shape without the need for a central column. The structure radiates around a central void, creating a flowing, sculptural movement between floors. Helical stairs can also be designed with elliptical or oval geometries, offering versatility to suit both classic and contemporary interiors.

Why Precast Concrete?

All Kallisto staircases are made from precast concrete, crafted in our offsite factory using flexible steel formwork for unrivalled accuracy and consistency. This approach allows us to deliver exceptional quality while reducing on-site labour and waste.

Compared to in-situ methods or alternative materials like steel or timber, precast concrete offers numerous advantages:

  • Cost-effective and long-lasting
  • Inherently fire resistant
  • Excellent acoustic insulation
  • Safe and load-bearing from the moment of installation
  • Easily finished with timber, marble, stone, tiles, or carpet

A Statement of Structure and Style

With its graceful curves and monolithic presence, a helical staircase by Kallisto provides more than access between floors, it creates a powerful architectural feature that defines your space.

Every staircase is:

  • Tailored to your design and structural requirements
  • Delivered as a single-piece precast unit for smooth, seamless installation
  • Finished to your specification, ready for balustrades and surface materials of your choice

Our goal is to craft staircases that not only meet your functional needs, but enhance the beauty, flow, and value of your property.
