I'm building a small double storey (habitable) porch/infill and I'm a bit stuck with the cavity.
It is, certainly for me, a bit hard to visualise so I hope my images help:
The new door will go in the opening at the front, the outer skin of the inner right hand wall will be removed behind the down pipe and it's the bit in front of the downpipe that I'm stuck with. I was originally going for option A, extending the inner skin with a nib - a messy job toothing bricks in with our lounge on the other side. I'm now wondering whether option B might be acceptable? To me it looks technically wrong, in terms of thermal bridging and damp penetration but it would be a lot easier and would retain the strength of that external corner.
Alternatively, if there's another option I'd be interested to learn?
Thanks
Edit: I did consider option C, seems easiest of all (and the reason for removing the outer skin is to maximize internal space in the porch), I'd just need a longer lintel over the door to reach the inner bearing, but I would end up with a 150mm section of uninsulated single skin brickwork (could it be lined with celotex?)
