My name isXXXXX and I'm happy to help with your question today.
Looking at the P(LBCA)A 1990 it refers to 'ANY' works for alteration or extension.
On a strict interpretation of the word 'ANY' this would include 'ANY' work to restore the building to its original state.
Unfortunately,failure to comply with s.7 is a criminal offence carrying sentences of up to 2 years imprisonment.
I hope this helps. Happy to discuss further.
Thanks for your answer, its the 2nd half of that sentence that I am querying, as it is any works 'which would affect its character as a building of special architectural or historic interest'
My argument is that the works we are doing will not affect its character as a building of special architectural interest is it is only recent (around 7 years ago) alteration works that we are undoing. Surely if the walls (stud) that we are removing are post the building being listed they cannot be covered by the listing?
