Replacing(?) wood panelled wall under Victorian staircase

[michaelj]

We are hopefully replacing our staircase shortly, and I'm wondering about the triangular wall underneath the main lower straight section.

The side facing the hall appears to be plasterboard, the internal side is (original) wooden tongue and groove panelling, but tatty (and cheap looking - it was only visible when accessing the coal cellar). I presume there are battens or something in between the two layers.

Is there a normal procedure for replacing these walls, possibly with a mini stud wall with plasterboard one side and chipboard or ply the other? Or any terms to search for? not had much luck Googling for this!

The choice is yours, since there's a cellar down below it might be prudent to go for a standard stud style wall with celotex insulation sandwich.

It's up to you how you clad it, although I assume your plan to do the inside wall with wood based sheet either for hand rails, bump proof reasoning or because you might build on storage.

Best suggestion I can think off is to have a minds eye on what neighbours and friends have done and go with something you like, bu is in keeping with the house.
