Hi,
I am digging out the footings for a outershed myself before getting a bricky in. For context I want to build a breeze block double skin outershed, the breeze block double skin walls will be on both side and back of the outershed but the front will be breeze block and bricks.
I started digging out my footings to roughly 450/500mm deep but along the boundary wall, I noticed my boundary wall was slanting (see pic) and I've dug out the 4 layer brick wall and then found out they are resting on slabs (see second pic)
Now as this wall is no more and I want to bring my outershed to this wall, do I need to dig all the way down and beyond to my neighbours foundation? Or do I just got a little deeper?
Just note that my street where is live is downhill so our back gardens are different levels.
Any advice on this would be greatly appreciated.
Thanks in advance
