How can a window overhang the boundary unless you have also gone into his

That certainly hasn't happened. But his contention is that it's the
outer surface of the timber construction (Marley Cedral cladding) which
is over the border.

As I said, if the overlap *is* there it's pretty minimal. His argument
seems to be that an inch (or even a fraction of an inch) is as good - or
rather as bad - as a mile.


Again, hard to judge without photos or plans but if the 2 houses started
off as mirror images of one another a simple test is this.

Could you neighbour carry out *exactly* the same conversion as you (with
mirror inversion) to *exactly* the same position on the party wall as you?

If not, then I suspect your builder may have gone beyond the centre line
of the party wall and you need to see if you had permission to do so.
