A helical staircase, also referred to as a helix staircase, is a self-supporting architectural feature defined by a continuous curved structure, offering both luxury and space efficiency. Unlike a spiral staircase, the helical form does not require a central column, giving the design a more fluid and open appearance. This curved staircase design is often integrated into high-end developments across London, England, and the United States, where architectural refinement meets spatial practicality.
Architects and interior designers specify bespoke helical staircases in luxury residential and commercial buildings, including landmark properties such as Brettenham House. These staircases serve not only as vertical circulation paths but also as sculptural focal points that elevate the interior.
Glass, metal, timber, and stone are common materials in helical staircase design, each contributing to a tailored finish that reflects the identity of the building and its occupiers. Whether enhancing a family home or a corporate headquarters listed on the London Stock Exchange, the integration of a space-saving helical staircase brings lasting value and design prestige.
From joint venture structuring to final installation of helical staircases, the Helical team delivers results that reflect careful research, user-centric planning, and seamless execution, demonstrating how one product can redefine the way spaces work and touch everyday life.
What is a Helical Staircase?
A helical staircase is a self-supporting curved staircase design that follows a smooth, continuous arc without the need for a central column. Often compared to a helix, its sweeping form adds movement, lightness, and sculptural elegance to both residential and commercial interiors. Unlike a spiral staircase, which revolves tightly around a central pole, the helical form allows for broader curves, spacious treads, and uninterrupted vertical flow.
Key Characteristics
Feature | Description |
No Central Column | Creates an open void in the middle, allowing better light flow and visibility. |
Wider Radius | Offers a broader curve than spiral stairs, improving comfort and spatial openness. |
Sculptural Form | Functions as a statement piece—part staircase, part architectural sculpture. |
Material Flexibility | Commonly made from glass, timber, steel, or concrete to suit design intent. |
Helical vs Spiral Staircases
Comparison Point | Helical Staircase | Spiral Staircase |
Support Structure | Self-supporting; no central post | Supported by a central pole |
Shape | Smooth arc with a flowing, sweeping curve | Tighter, circular twist |
Aesthetic Impact | More elegant, open, and sculptural | More compact, functional, and vertical |
Spatial Use | Ideal for open-plan, luxury interiors | Suitable for tight or secondary access |

These pros and cons reflect real-world feedback from architectural research, design services, and hands-on work from the helical team. Used in projects like Brettenham House and led by designers such as Martina Malone, each staircase aligns with the joint venture structuring, spatial logic, and design ambitions of the client.
What to know before installing helical stairs?
The installation of a helical staircase demands precise planning, structural awareness, and alignment with both design vision and regulatory compliance. Whether incorporated into a luxury development in London, a family residence in England, or a commercial space in the United States, the process involves multiple architectural and logistical checkpoints.
In projects such as Brettenham House or within high-spec interiors led by designers like Martina Malone, proper coordination between the helical team, the director, and structural consultants is essential for achieving both safety and visual integrity. Below is a structured table detailing the core installation considerations for bespoke helical staircases:
Category | Consideration | Description |
Planning & Design | Accurate Dimensions | Measure the floor-to-floor height and stair diameter to ensure proper fit and balance. |
Building Code Compliance | Align with English and local regulations for rise, going, tread spacing, and headroom (min. 2000mm). | |
Staircase Orientation | Evaluate the entry and exit points for natural movement and optimal positioning. | |
Design Intent | Match the material and finish to the architectural context and occupiers’ expectations. | |
Site Conditions | Structural Load Support | Ensure the base and floor slab can support the full weight of the helical staircase. |
Opening Requirements | Prepare a precise ceiling opening to accommodate the staircase form and clearance. | |
Access and Delivery | Confirm site access for transport and delivery of staircase components. | |
Obstruction Check | Identify and avoid interference from underfloor heating or hidden services. | |
Technical Needs | Alignment Precision | Use digital tools or modelling to verify that the curved staircase design follows correct geometry. |
Secure Anchoring | Fix the staircase using the appropriate method depending on the base material (timber, concrete, etc.). | |
Final Touches | Apply coatings or protective finishes post-installation for design consistency and product longevity. |
These elements reflect key insights from research, real-life work, and multi-sector services involving helical stairs. From joint venture structuring to design events, every helical staircase design must account for spatial logic, user movement, and long-term architectural value. The right installation approach ensures the staircase not only fits but also elevates the way a development connects life, space, and structure.
