(Using a link instead of picture as not sure if newsgroup allows pictures)
I'm re-doing the bathroom over the next few weeks (months?) and this
includes a builder knocking a big hole in the wall to extend the bathroom.
See the plan in the attached JPEG. I'm not sure how accurate the builder can
be in making the hole the right size (going to ask today) but I envisage a
gap between where the stud wall and the existing brick wall. I'm assuming
it's brick - 100 year old stone cottage, looks about a brick thick.
How would you go about filling that gap? All the walls in the bathroom will
be tiled but I'd probably like to "make it good". A piece of wood would be
obvious but can you plaster/tile over that? I guess is depends how big the
gap is :-) Maybe a very long thin strip of plasterboard? Even, so they'll
still be a gap - mortar for the bulk of the gap with plaster on top?

Your jpeg has come through ok on your first post.
Will this be the start of a jpeg sending craze !!
I too did not know that the ng supported them.
Cant help with the query - sorry.
Freaky. It's there on your first post but I assume that's because it just
stayed on NTLs news server for us.
I believe this NG does not support them & that NTL can't set up a news
Back too the question, the stud wall will have some fixings in the gap, I
guess you want something to provide a surface for plastering. If you are
lucky the wall will be cut flush to the stud, if not fill with tightly
balled newspaper, odd bits of board, timber offcuts etc. Just raid the waste
pile and stick some undercoat plaster over that.
I realise that hence the reason I posted again with a link instead (a lot
more work on my part :-) I can understand the netiquette bit (mainly a
concern for dial-up users) but the occasional 50KB JPEG isn't *that* bad. Of
course, I was careful to not post a large attachment, others won't be so
careful.... I always thought it would have been more useful to limit the
size of individual posts.
I've got a similar issue coming up. However, I want to wet plaster over a
similar gap. Does anyone know if low expansion expanding foam is the
solution, followed by a few cm of bonding plaster?
Leave about an inch depth for bonding plaster and it will be fine.
Yo can even use expned Al mesh instead of foam, or in fact bundled
newpapers or anything similar.
Another thing I have done where I had a deep but not very wide crack, is
foam to within an 1/8" of the top and then decorators caulk.
Its still soft to the touch, but it serves to make a neat paintable job.
I forgot to mention, it is in an old chimney with a capped off flue.
Obviously, it is long since a fire could be lit there, but a gas range
cooker (not Aga type) will be going into the hole. I've already lined the
inside with Fireline plasterboard. Will expanding foam be a fire hazard at
all? I would suspect (hope) not, as it is shielded by the Fireline.

G = gap to be filled and plastered. Varies from 2cm to 4cm in width.
# = 12.5mm Fireline plasterboard.
I'm aiming to try and take the stud wall against the brickwork if possible
but don't want to move the hand stud wall too far to the right otherwise the
open door will overlap the basin. It all depends upon how accurately the
builder is when making the hole.

Good move, no it doesn't! (What's a munrobasher by the way?)
Your builder ought to be able to make it pretty damned close, if
that's what you want, which hopefully he's told you by now; however
the normal way of doing this would be to make the vertical line of the
hole (ie the end of the old wall) coincide with the end of a brick in
every second row of bricks, if that makes sense. Then he just has to
cut the bricks in the other courses at the midpoint (far easier than
having to cut the bricks in every row, which sometimes means just
trimming a bit off the end .
(Alternatively he could use a Stihl saw to zip up the wall at exactly
the point you want?)
Assuming the first option, I would then pack out the gap using timber
of appropriate thickness, before the vertical stud is put in place.
Presumably you'll have plasterboard on the outsides of your new stud
partition; hack back a few inches of plaster where the old wall
terminates, and run your plasterboard round the corner and beyond,
overlapping the bricks by the few inches. The whole lot can then be
skim-plastered to cover the join. Alternatively, you could use
undercoating plaster to cover the timber packing, spanning the gap
between the bricks and the corner.
 How crucial is the positioning of your new corner, anyway? Can't
it just end at this point, ie to the nearest half-brick length?
