Go to our Measurement guide to learn how to measure your room for a loft spiral staircase.
A spiral staircase compared to a traditional main staircase will save you space within your room layout. The design of a Spiral Staircase is round, and it means that treads are positioned within the diameter mentioned. They will not take up more room than that. A spiral stair will typically be tucked into a corner location of the room which then maximises the rest of your living space.
Our focus is private staircases for access to habited space. Building regulations in relation to spiral staircases for private use, it is essential that all steps/treads have the same rise. The individual tread rises measures no more than 22 cm. Another important factor is that you cannot have gaps of more than 10 cm situated between the balusters or the individual treads. Riser bars (child guards) can be fitted between the treads to reduce these gaps. Spiral staircases may also need a minimum clear stair width of 60 cm. All these aspects covered are just guidance and it will be the decision of the building inspectors to judge whether your spiral stair meets the regulations.

Matching landing balustrades is available for Montral Spiral staircases. The balcony balustrade are with vertical filling to provide high safety. This matching landing balustrade or parapet railing is a big part of the visual beauty at the stairway.
