Helical vs Spiral – What’s the Difference? 

When it comes to adding a touch of luxury and elegance to a new build home, few architectural features can match the impact of a beautifully designed staircase. Opening the front doors to an entrance hall complete with a showstopping staircase is one way to take people’s breath away. 
Among the most popular choices for homebuilders and developers looking to make a statement are helical and spiral stairs. Both types offer a unique aesthetic and functional appeal, but they are distinct in design and application. 
At Kallisto, we specialise in creating stunning precast concrete stairs that bring both luxury and practicality to a property. Helical and spiral stairs are two of our most sought after options, and we work with many architects and designers to create and build bespoke staircases to their unique requirements. 
Incorporating a helical or spiral staircase into your home is more than just a design choice; it’s a statement of elegance and luxury. We understand that your home is a reflection of your personal style and aspirations. Our stairs are designed to complement and enhance your living space, adding a unique architectural feature that is both functional and beautiful. 
Helical and spiral staircases are similar in the fact that they offer a curved, eye-catching aesthetic – in fact they are often mistaken as the same thing. So what is the difference between these two variations? 
Helical Stairs 
Helical stairs, often referred to as curved stairs, are characterised by their graceful, sweeping curves that form a continuous arc without a central support column. 
These stairs resemble the shape of a helix, providing a smooth and elegant ascent. Due to their shape, they are often seen as more sculptural than a typical spiral staircase – almost like a piece of function art in your own home. 
The absence of a central pole means that helical stairs typically require more space than spiral stairs, but they offer a striking visual appeal that can serve as a focal point in any home.

Spiral Stairs 
Spiral stairs, on the other hand, are built around a central pole or column. The treads, or steps, radiate around this central point, creating a compact and space-saving design. 
They are probably most associated with ancient castles where they were commonly used in towers, however modern spiral staircases can create a minimalistic, contemporary feel within any interior. 
Spiral stairs are ideal for areas where space is limited, such as lofts, small apartments, or secondary staircases. Despite their smaller footprint, spiral stairs can still offer a sophisticated look, especially when crafted with high-quality materials. 
Key Differences Between Helical and Spiral Stairs 
- Design and Structure: The most obvious difference is the presence of a central support column in spiral stairs, which helical stairs lack. This structural element affects both the aesthetic and the space required for the stairs. 
- Space Requirements: Helical stairs typically require more space than spiral stairs due to their wider curves and lack of a central column. This makes them more suitable for larger homes or open-plan areas where they can be showcased. Ideal in grand entrance halls or communal lobbies. 
- Aesthetic Appeal: Helical stairs often have a more fluid and organic look, making them a popular choice for homeowners seeking a luxurious and modern design. Spiral stairs, while also attractive, tend to have a more industrial or compact appearance. 
- Functionality: Both types of stairs are functional, but their use cases can differ. Helical stairs are often used as a grand central staircase, while spiral stairs are favoured for secondary access points or in tighter spaces.
