I'm planning a loft conversion but must have stairs no wider than 55cm ito the loft space. This is because of constraints that can't be overcome. The building regs guys at my council say that they must be at least 80cm wide to comply with BS 585 Part 1.
I've looked at part K of the regs and it says (and i quote) "no recommendations for minumum stair widths are given".
Is the guy right to quote BS 585 as part of his building regs approval decision? Could he not approve because of the stair width??
Any advice would be appreciated.
