Stair return barrier - building regs
I have a staircase that turns at the bottom with fan steps. The main staircase steps leading down to the fan return used to face a wall but this wall has been removed to extend the hall. There is now a 24 inch drop to the floor from the fan skirting.
I presume there are building regulations that stipulate a barrier to be at the end of the stairs. What should be the minimum height and width of this barrier. Does the barrier need to run across the total width of the staircase or can it be less?
