I have a brick inner, stone outer, rubble filled wall. The outer stone layer had a window cut in it and now the opening is supported by a large steel. We deliberately recessed the steel about 3 inches and all the build back bricks to support the stone because the original plan was to clad it with cuttings of stone removed from the wall, then strip the pebbledash from the rest of the stone wall, so the whole thing would look stone
I've since changed my mind abo removing the dash, as it seems to be a vital weather resisting component, is a huge amount of work, waste, and I'm not that bothered to see the stone (it would also upset the character), so it's going the get sandtex Plymouth grey on it instead. Around the window there will be a decorative band of buff render, and above this a bit of pebbledash needs patching in
Because stone slip was going in there but now is not, I'm left with a recess in the wall 3 inches deep that I need to fill with something that won't crack or drop off. Whatever it is will need to take a render, and can be mortared to the wall. It could also be mechanically fixed with concrete screws. It'll probably need to be about 2 inch thick to allow back mortaring and also face rendering/dashing
It's the dark heavy outline in this beautiful sketch:
