From quarter turn to straight, pros and cons
Staircase design plays a crucial role in both the functionality and aesthetics of a space. A quarter turn stair features a 90° turn with a landing or winder steps, while a straight stair is a continuous, unbroken flight.
Choosing between these options involves weighing the benefits and drawbacks based on space constraints, design preferences and practical needs. Below are the pros and cons of transitioning from a quarter turn stair to a straight stair.
The images above show quarter turn and straight designs, created in our stair calculator, StairDesigner.
Pros of a straight stair
Space efficiency
A straight stair often requires less lateral space compared to a quarter turn stair, making it suitable for narrower or more linear spaces.
Simplified construction
Straight stairs are easier and faster to design, fabricate and install due to their simpler geometry and lack of turns or landings.
Cost effective
They typically involve fewer materials (e.g. no need for additional support structures like newel posts or intermediate landings), which can reduce costs.
Aesthetic appeal
Straight stairs offer a clean, minimalist look that works well in modern and contemporary interiors.
Ease of use
Straight stairs provide uninterrupted travel, making them more accessible, especially for moving furniture or for people with mobility issues.
Better light flow
Without turns or landings, straight stairs can allow more natural light to flow through a space, especially if adjacent to windows.
And the cons compared with a quarter turn
Space requirements
Straight stairs often require a longer run, which might not fit in compact or multi-functional spaces. A quarter turn stair can work better in tight layouts.
Lack of rest points
Without a landing or break, straight stairs can be more physically demanding to climb, particularly for older individuals or those with limited mobility.
Safety concerns
A continuous straight run can lead to higher risks of injury in case of a fall, as there’s no intermediate landing to break a potential fall.
Less visual interest
Quarter turn stairs add character and visual complexity, which can enhance the aesthetic of a space, especially in traditional or intricate designs.
Structural challenges in retrofitting
If converting an existing quarter turn stair, structural changes might be required to accommodate the straight stair, potentially increasing costs and complexity.
Making your changes in StairDesigner
In StairDesigner, modifying a stair design is straightforward. The image below illustrates a quarter turn stair.
To convert this to a straight stair, simply delete the last flight.
When making this change, ensure the number of steps and tread width remain consistent with the original design. A practical approach is to combine the longest dimension of the second flight with the shortest dimension of the first flight. This method helps maintain the overall dimensions close to the original quarter turn stair.
Finally, adjust the length of the straight flight as needed to complete the design.
Modify a straight staircase into a quarter turn
In this case, you just need to add a flight in StairDesigner with the desired length and reduce the length of the first flight to meet a coherent set of stair parameters.
Which is more common?
Straight stairs are more common in modern, compact designs or utilitarian spaces, while quarter turn stairs are highly popular in traditional and mid-to-large-sized homes where space allows for their added functionality and aesthetic value.
Ultimately, the choice between the two often comes down to the specific layout, style, and needs of the building.
Further design variations
We’ll take as an example a standard quarter turn stair.
Designing a quarter turn stair presents various options depending on manufacturing methods, space usage, design aesthetics, and considerations for comfort and safety. Below, we explore key aspects and variations for creating a functional and appealing quarter turn stair.
Manufacturing
The manufacturing approach significantly influences the stair’s design. Here, we assume that the handrail will always be straight. Adjustments often start with modifying the outer stringboards to achieve a straight, linear top edge.
For quarter turn stairs, this adjustment may cause a visual issue where the winding steps at the corner disrupt linearity, potentially leaving parts of the structure inadequately covered.
In such cases, StairDesigner allows the customisation of stringboard shapes, ensuring a perfectly straight top side and a well-aligned underside that appropriately covers all steps.
Efficient use of space
Optimising space is a critical consideration in stair design. Quarter turn stairs can be adapted to include storage solutions beneath the staircase. For instance, extending the newel base to the floor and the right stringboard on the first flight provides structural support for integrating cabinetry below.
This adjustment not only maximises available space but also enhances the functionality of the design, making it ideal for compact or multifunctional areas.
Design flexibility
Quarter turn stairs offer opportunities to complement the architectural style of a space. By varying the design elements, the stairs can blend seamlessly with the overall aesthetics.
For example:
Open staircases
These feature cut stringboards and no risers, creating an airy and light-filled effect. Moving the handrail to the wall side further enhances the open structure.
Central cut stringer designs
Using a central cut stringer with thicker steps provides a modern, minimalist look while ensuring robustness.
Both options demonstrate how quarter turn stairs can adapt to different design goals, from traditional to contemporary styles.
Comfort and safety
Safety and comfort are often prioritised, especially in residential and high-traffic spaces. To enhance these aspects, the following modifications can be made:
- Adding handrails on both sides for increased stability
- Incorporating larger flights for more comfortable navigation
- Using straight steps and intermediate landings to improve safety and comfort
These adjustments ensure that the stairs meet the needs of diverse users, balancing functionality and user experience.
Quarter turn stairs are highly versatile, accommodating a wide range of design preferences and functional requirements. By carefully considering manufacturing methods, space utilisation, design aesthetics, and safety, you can create a staircase that not only fulfils its purpose but also enhances the overall appeal and usability of the space.
Whether prioritising efficiency, style, or comfort, quarter turn stairs can be tailored to meet your specific needs while seamlessly integrating into any architectural setting.
