Winder Stairs
Precast Concrete Winder Staircases
Space-Saving Design, Engineered to Perfection.
Winder staircases, also known as dog-leg stairs, offer an elegant solution for properties where space is limited but style is essential. At Kallisto, we manufacture and install fully bespoke precast concrete winder staircases, designed to make the most of your layout while adding architectural character to your space.
Every staircase is tailored to your exact requirements, with a smooth, efficient process from design through to installation. With Kallisto, achieving your dream staircase is simpler than you might expect.
What is a Winder Staircase?
A winder staircase uses triangular or wedge-shaped treads to turn a corner without the need for a landing. These stairs are narrower on one side than the other, allowing the flight to change direction and conserve space. When arranged in a series, they can form a curved or spiral stairway, adding visual interest while maximising usable area.
This makes them ideal for:
- Compact homes and townhouses
- Interior retrofits
- Modern multi-storey developments
- Stylish access to upper levels
Bespoke Luxury, Built for Safety
Choosing a precast concrete winder staircase from Kallisto means you never compromise on safety or quality. Each staircase is installed as a complete unit, offering an immediate working platform and providing safe, stable access to upper floors from the moment of installation.
Designed and cast in our Essex-based facility, our precast method ensures consistency, precision, and total control, all essential for high-end results.
Precision Built with Less Waste
We use a flexible steel formwork system to manufacture our stairs offsite. This ensures every unit is made to exact specifications, reducing waste and improving sustainability. Unlike in-situ concrete, where formwork is discarded after each pour, our controlled process allows for efficient reuse and minimal material loss.
This means:
- Faster production times
- Cleaner, greener manufacturing
- A superior finish with lasting durability
Benefits of Precast Concrete Winder Stairs
Compared to timber or steel alternatives, precast concrete offers exceptional advantages:
- Fire resistant by design
- Excellent acoustic performance and sound insulation
- Durable, long-lasting, and low maintenance
- Ready to use immediately upon installation
- Compatible with high-end finishes including timber, marble, stone, tiles, and carpet
A Kallisto winder staircase provides both a practical and aesthetic solution, supporting your interior vision while enhancing the safety and value of your property.
