Box-room ceiling is still the original strawboard covered in woodchip
wallpaper. All other ceilings in the house have been covered with
plasterboard and I have just done the same here. Plasterboard is screwed
into the joists through the existing strawboard. However on the outside
wall there is no joist. It looks as if the strawboard was put up before
the walls were plastered so are supported at the ends. This option is,
of course, not open to me.

From what I can see there are several ways of approaching this:-

1) Ignore it, and hope that the screws into the adjacent joist are
sufficient.

2) Screw into the strawboard with some suitable type of fixing designed
for fixing to plasterboard.

3) Glue the end to the strawboard using something like No More Nails.

4) Screw into a new batten in the loft.

As far as I can see 1) is a non-starter, 2) looks a bit suspect, 3)
three might work but by preference would be for 4)

Am I missing anything? Is there anything else I should consider?

==================================
You could have used the wall plaster to support the plasterboard by
cutting out a small channel at the top of the wall into which the
plasterboard would have fitted as the original strawboard did. Since
that's no longer an option (unless you feel like re-doing the job) you
could attach a decorative wooden batten along the wall to support the
plasterboard. If you don't like the look of the wooden batten you could
cover it with a cornice or even use a cornice alone.

Well that's one option I hadn't considered. I do need to take down what
is already up there to turn it around because I mistakenly assumed that
when it said 'plaster other side only' it meant paint this side. As it
is only a box-room I see no point it getting it skimmed.

Actually thinking about it further that probably isn't going to work. I
would have to move the board a little into the new gap and that would
open up the same problem at the other end where it is currently held by
the new plasterboard on a new wall.

But thanks for the suggestion.
