MONTRÉAL CLASSIC 3 is a minimalist staircase with 3 balusters per tread ensuring a simple and discrete look. A spiral staircase is 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.

Leading interior designers have contributed in the creation of MONTRÉAL concept, and they all agree “Interior trends today go toward minimalistic design and the option of personal customisation using high quality materials”. Customise the staircase to your needs and interior design by selecting from the drop-down menu above.


The spiral staircase MONTRÉAL from DOLLE comes with either 11, 12, 13, or 14 treads including substantial landing platform. The staircase can reach a maximum floor-to-floor height of 352,5 cm. It can be adjusted to suit heights as low as 210cm, you can do this by removing spaces or treads to reach you desired height. Each tread has an adjustable rise of between 20,5 cm to 23,5 cm for the perfect fit to any height.

For the staircase to be comfortable to climb you will need to have an opening of 130cm round or square for a 120cm staircase or 150cm round or square for a 140cm staircase.


We offer a matching landing banister that will add the final touch, this is important for safety that the banister is 90cm high and has no gaps wider that 100mm. Just measure the length you need, first you will need a starter kit this is 2 metres long and will give you the components to join the banister to the staircase, then you can purchase as many 2 metre extension packs as you like. To give you an example, if you have 4 metres that’s simple that 1 starter then then 1 extension pack. If you have 3.8 metres you can cut the second pack down to size. The landing banister will seamlessly flow from the staircase. You can see our range here landing banister.


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.
