Chris,

Thanks for that.

Like others, I am finding it a bit hard to get my
head round the situation.

I understand that: there have been times when I've been in much the same
situation.

I'll try to post a more detailed explanation a little later, with some
photos if I can manage it, but the basic dispute is this:

For whatever reason, the end wall of the new rear extension and dormer
was not built in exactly the position shown on the council-approved
plans; the brickwork (of the extension) and the timber construction (of
the dormer) are both within my side of what the drawings describe as the
"alleged centre line" of the party wall, but a uPVC end fascia, some
cladding and some tiling all overhang it.Â* If the centre line is
accurate then the maximum overhang is 40mm (the tiles) and the minimum
is 20mm (everything else).

If the overhang exists then I am in breach of my planning permission and
will have to reduce it.Â* But whether or not it does exist, and if so by
how much. depends on the *exact* location of the boundary line, so that
is what has to be determined.

The daft thing is that when my neighbours planned a further extension
set back 6" from the boundary, my official comments on their plans was
to suggest that they built right up to the boundary, with any fascia
overhanging my land - so that if I wanted to build an extension in the
future, it could be butted right up to their brickwork, just like the
existing extensions!
