How to secure a slope and design a garden entrance cost-effectively?

We have rubble stones and the new walls will also be built with them. We still have to fill in some parts. I hope my cousin can get me some soil - he builds riding and sports arenas. Nothing is level with us.

I find rubble stones very beautiful! It will definitely turn out great! Are there any photos of your [Außenanlage]?

They do not exist yet.
The bricklayer does not work in the frost. Rightly so.
The old barn and stable wall has remained standing and holds back the slope.

I will take some photos tomorrow.

You really have an overview there [emoji847]. But I can't quite imagine your hillside right now. I'm looking forward to more pictures in the near future [emoji4]

The house is downstairs. No overview

Ah, then I actually misunderstood it.
