Hello,
I tried fixing a curtain bracket next to one of our windows but couldn't get any hold. Exploring further it turned out that there was rotten wood and hollow space behind it. So I continued and removed the plaster covering the hole.
There were dry wooden bits in it and plaster. I removed all of that and reached solid brick at the back of the whole (around 14 cm deep). I assume the wood is from the transition between window frame and wall. The window frame has seen better days (and probably we'll have to get the entire thing changed at some point next year).
In the meantime I would like to fill this hole so that I can finally put that curtain bracket in.
My original idea was applying something like this https://www.screwfix.com/p/ronseal-big-hole-ready-mixed-wall-filler-grey-1-2ltr/95289 but given the depth and size of the hole I would probably have to apply loads and in 3 layers (as maximum application is 50 mm).
The other thought I had was cutting a piece of wood to fit into the wall, fix it to the bricks with an anchor and then apply the filler on top of it and around it. Would just have to be careful to not place the "anchor" screws where I want to put the screws for the curtain bracket.
Would be good to get your suggestions and what you would do in this case.

The window is to the right. Can see that the general wood of the outer window frame is not in a good state.
