Hi,
I'm currently replacing a large window with a set of French doors in a kitchen extension with a flat roof.
The brick is engineering standard and the mortar appears to be concrete as it's incredibly difficult to chisel out. The picture attached below shows what it took my an entire day to do armed with an 850W rotary hammer, club hammer, bolster chisel and air chisel:

Don't be alarmed at the one brick stuck in the centre, there's no way it's going to fall down as it's absolutely solid. Removing brick and mortar was like working on solid stone!
Anyway, my main question is that I have a concrete lintel that I will be putting in tomorrow. Is a 150mm overhang on each side sufficient?
My other question is how should I best go about this? I intend to fit the lintel on the outside and then remove bricks from the inside and fit another lintel there. Is this OK?
