I live in a garden fronted terraced house that is some 8 foot above the road. The stone wall that holds the garden has come away from the side walls at either end and has to be dropped and rebuilt before it collapses on someone. I am considering replacing the soil with stone, to allow drainage, and putting in weepholes at the base to allow water to run off.
However, I have been told that I will need something like 7m3 to fill the void left (7x13x5) and I'm not sure that, even if I back the stonework up with blockwork, it will hold such a weight.
Any advice much appreciated.

Remember that it will be a spread load and much lighter because it won't be soaked earth, the water will drain to the weep holes. You will need a structural engineer for a wall that high, especially a retaining wall. It will probably need rebar and concrete, then your stone facade.

The measurements I gave were Imperial, the wall is 5' high, the garden runs 7' back from the wall and is 13' wide.
The cube area to be removed is actually some 12.9m3 I am now informed. Would slabbing (laying them on their side) the block help at all?

the wall was consyructed wrong if it collapsing. I can't sdvise on slabs for that height. I would consult a structural engineer and have it done right. Retaining walls need to be anchored into the foundations with steel
There are blocks on the market that you can use as a retainer but the name escapes me. No doibt someone will let you know

It's just a front wall that's been there for over a hundred years and is now showing it's age a bit.

The side walls seem ok, no cracking or anything on the pointing, it seems to be wet soil and no drainage that's caused the prob.

its FUBAR now yogi
it will have to be redone and probably some up the side as well to tie it in
possibly and i am not qualified to say this,there may be an anchoring system you can use without removing the wall to keep the wall in its current position
but an engineer will tell you best
