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 1 metre long and will give you the components to join the banister to the staircase, then you can purchase as many 1 metre packs as you like. To give you an example, if you have 4 metres that’s simple that 1 starter then then 3 extension packs. 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.

As a safe basis, a foundation is necessary for the DOLLE Toronto. Plan the foundation at least 40 cm x 40 cm x 40 cm (L x W x D). This information corresponds to normal soil conditions.
