I've got a mangy old shed that is sitting on a small patio area. about 50cm
above the garden. The garden rises up at the back of the shed, which was p
art of an old railway embankment. Hopefully the photo makes it clear what's
My plan is to dispose of the old shed and lower the patio area where the sh
ed currently sits so that my new shed can extend onto the garden a bit.
My question is, what's going to be the easiest way of retaining the bank at
the back of the shed as I dig down? I don't want the existing retaining wa
ll at the back of the shed to collapse as I lower the level and I don't wan
t to have to shift more earth than necessary.
Does anyone have any bright ideas about what I could do or what I need to w
atch out for when I'm digging away?

Looking at that pic, if it's really just the lowest tier that you're
digging away, I don't think it's going to be too big a problem, so long
as you're happy to keep a shortish step. If you want to go all the way
back to that existing wall, and just extend the bottom of it, then you
may well have to rebuild that whole wall, though.
Are you sure that there *is* a retaining wall at the back of the shed?
Or is the patio simply at the level of the sloping surface at that point?
If you drop the level at the back of the shed to that of the garden in
front of the patio, you'll almost certainly need to build a retaining
If I'm wrong, and there *is* one already, everything will depend on the
depth of its foundations. If they go below the required new level,
they'll be ok. If they don't, digging will undermine them, and the wall
will probably collapse - so you'll have to take it down and build a new one.

(I finally appeared to have worked out how to use this stupid google groups
interface). Anyway, that's my conclusion too. If I go ahead I'll either so
rt out the retaining wall properly or build the shed on two levels. Buildin
g it on two levels might actually look better in the small garden as it'll
help break up the roof line.
+1 from me for not disturbing the retaining wall. Personally, I'd extend
the patio thingy over the lawn, so there's then no arguing about the
height of the shed, and it gives you a nice firm foundation.
I find the idea of a two level shed hard to envisage.
1. can you reduce the weight by making the slope less acute?
If not I saw a wall down my road that was built like a dam, ie curved
toward the earth bank with deep posts at either end with girders inside them
to retain the pressure,so, presumably as the earth slides and pushes the
wall the wall gets its bricks pushed together pushing the end pillars out
but they are too strong to move, at least they seems to have been there a
good ten years so far.

In case anyone is interested, the conclusion is that I won't be digging any
thing away. Apart from rebuilding the retaining wall being a bit like hard
work, I also end up undermining the fence posts so its more trouble than it
The current plan is to build a large a shed as possible on the existing pat
io area (it can be about a foot wider and 3 feet deeper than the current sh
ed) and put a separate narrow storage shed at the side of the garden so the
new shed doesn't get full of crap.
Thanks for everyone's comments.
