MONTRÉAL from DOLLE is a high-quality spiral staircase series designed to make the most of unused space in the home. MONTRÉAL CLASSIC RANGE provides minimalist look with up to 5 balusters per tread. Spiral staircases are the ideal solution for rooms where space is at a premium.
The staircase is available in two widths 120 cm or 140 cm, treads in solid beech or oak veneer and three choices of colour white, grey or anthracite.
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.
IMPORTANT: It is your responsibility to ensure that spiral staircase, handrail and landing banister are safe. If you have doubts, please contact your local building authority.
Matching landing balustrades is available for Montreal 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.
You have the option to add extra components to your MONTREAL spiral staircase to make it safer. You can close the gap between the banister by adding a middle banister pack, if you add two then the space in between will be less than 100mm which is a requirement for UK building regulations for a main staircase. You can also close the gap between the treads using our riser bar kit, this will make the staircase safer to climb and ensure you meet building regulation requirements for main stairs.
The pitch height can be adjusted with spacer rings from 20.4 to 23.4 cm depending on floor height. We advise you use as little spacers as possible as this will mean narrow gap between the treads, this will make your staircase more comfortable to climb.
