Dad and I went to the house today to level off the garden. It slopes upwards from the house to the back of the garden which is ok, but it also slopes down towards the garage and this is quite a big drop. We built a dwarf wall along side the garage wall with a damp proof membrane in-between it. We then dug the soil from the top of the garden to raise the sides up so that the garden was level across. In removing the soil from the top of the garden we also made that be less steep.
