I am in the process of doing up a Victorian terrace and one of the tasks

The layout is the classic Victorian l-shape :-
_______ _______ _______

Do I 'own' x & y or y & z?

"x" and "y" are probably "yours", "z" probably next
doors. You will have to arrange to do "x" by agreement
with your L.H. neighbour. Your R.H. neighbour would
probably be very pleased if you did a *good* job,
but might turn very nasty if it was a bodge that
damaged brickwork or let water in. What are you
pointing with, BTW? How are you raking out the joints?
