I need to demolish a staircase in the next few days - the plan is to replace it with a staircase going in the opposite direction, to allow separate access to the third bedroom in a "2+1" bedroom Victorian terrace. I'm taking the opportunity to install a winder staircase going up from the rear reception room, so the new staircase will be less steep and will conform to modern building regulations.
The existing staircase is in the usual narrow Victorian terrace stairwall running across the house, enclosed on three sides, so both sides of the staircase are fixed to walls. Any suggestions as to the easiest way to demolish it?
