Maybe I see horses everywhere because I have a horse myself, but why so far away from the street? That is an eternally long access path/paving, which also makes the whole thing more expensive.
We have a similar hillside location. We have built a half-level into the slope. I don't know what it's called in technical jargon, but when you look at the house from the street, it looks like a bungalow. From the back, you can see both floors.
To get to the living rooms, you go down the stairs in our house. The garden is then behind the house. You can go directly from the living room into the garden on the same level.
I'll attach a few pictures. We are very happy with the solution. And we were able to hide the excavation on the property. Backfill is extremely expensive at the moment.
