Hi,
Yes thats the sort of thing, the wall goes from being two bricks deep to three on the foundation course, with half a brick showing either side.
We've just recently been lowering ground levels with a pebble filled drain all the way around the exterior walls to take the damp earth away from the wall.
The attached photo shows where we have worked around one of the exterior chimney breasts (the house was intended to be mid-terrace, but never got beyond a pair of houses).
You can clearly see the details of the foundation at the base of the chimney breast, a pretty typical arrangement as I understand.
If you are lucky round our way the wall will have been built off of a trench of compacted gravel. I guess ours has as it is still standing with no serious subsidence issues (fingers firmly crossed!)
The bit of wall to the right of the foundation is the back of our fireplace (the interior chiney-breast has been removed) and is single skin built off of the soil, the bottom course of bricks is where the soil level used to be. We have since, laid concrete at this low level and built up to those hanging bricks with a damp-proof course. We're hoping the conerete, which is angled to run away from the house, will help keep the foundations stable. Then have guilt the soil back up on top of the concrete, except for the pebble filled drain immediately adjacent to the house.
The line where the pebble-dash stops is where the level of the concrete used to be some 6" above the internal floor!
The concrete was 12" thick and took some serious work to remove with just a bolster and lump hammer i can tell you.
