Sloping a large front corner garden for rockery

Question

Hi.
Need some advice. I have a new build large corner front garden in the uk. I want to create a slope to create a large boulder rockery with conifers of differing sizes and other green plants.
My question
I have been putting stubs of grass from other places face down to raise the corner. What else do you recommend?
Thanks

Soil and stones will be really helpful in raising an area. Grass will decompose and leave you right back where you started as far as soil level goes.

A photo will help me to see what is going on, but usually if you want to fill an area or raise the level you will do this with soil, or filler rock.
