Getting a fixing on what has become a crater

[peige]

Got a hole in the wall where I need a fixing, a large hole. Its a 1940's house so predominately well built but with so many past diy jobs done on it over the years drilling holes and getting fixings can be "interesting"
I need to get a decent fixing in this exact place for a semi floating shelf, fixings are only 4" apart hence I say semi floating due to the load on the top fixing. The bottom raw plug is good and holding well.

I think I've got to fill this level and start again (the hole does get larger in diameter behind the bit you can see so filling should grip) but what to fill with, i think it needs to be something better than standard filler?

Your large hole, what thickness is that cream wall,& , difficult trying to work out from photo actual dimensions of hole

Looks about 100mm thick cream wall, I would square up base & side & cement in brick or two, a 1/2 at the bottom, & 3/4 on top.

When dry make good with plaster.

I'd just fill it with jointing compound and hope for the best lol.

Regular fillers shrink a lot when they dry so generally don't properly fill a hole and you just end up with a wobbly part of the wall on anything but a nail hole

Its a deep hold in places, like a flaming pot hole that disappears off towards next door.. when I hoovered out the loose stuff and pulled the nozzle away I could smell cigarette smoke from next door! Its a wall between the houses.

I'm pretty resigned to having to move the whole shelf up 2"

That brickwork looks shot and probably won't hold a plug, and that's not plasterboard (which otherwise could have held a shelf by itself).

Like NG suggested, chip out a chuck of plaster and repair the brickwork.
Even moving it up 2" is still going to hit the same area.
