We don’t sell custom made stairs.

Moreover, we note that our stairways are supplied in kit. 
The person who installs the staircase makes all necessary adjustments.

Before considering the purchase of a standard staircase supplied in kit, you should always check that it’s possible to place the staircase by controlling the following parameters: total height to climb, the ground space, dimensions of the hopper (opening in the ceiling).
