Hi,

My mother has a garden which has a fairly substantial slope (as above)
and is thinking of levelling it, and putting a supporting drystone
wall at the bottom (next to the drive). She is concerned about
drainage and cost.

I imagined that the best thing to do would be to clear back the soil,
fill it in with rubble and then put a holey tarp down and relay the
soil?

We have no idea whether this would be the right approach or what sort
of cost we should expect. We would be very grateful for any input at
all.

Kind regards,

Richard
