Build the house further down. You have to carry everything up the stairs or the path. First the stroller, then the groceries get heavier, it feels like the stairs get one step longer every year, then the body doesn’t want to anymore.
The access path must be cleared and gritted in winter.
The access path and the house connections cost more the longer they are.
You should think about the garden. Not about where which plants go, but about the spaces. The terraces and retaining walls must be done along with the house construction. Especially with such a slope, the next 100 k are quickly gone.
For a project around the million mark, the planning should be done by the architect.
Create a room program and let him work.
A room program does not only mean listing the rooms but also what they should include.
Dressing room 6 m of continuous closet + space for 500 pairs of shoes, which can optionally be in the wardrobe. Bed with the dimensions x. Maybe you have a longer bed because with your 1.99 m height the normal 2 m beds are too uncomfortable for you or you have a large one with a bulky, massive frame.
So your wishes, your special features.
That is also important for you. The existing or desired furnishings must always fit into the floor plan.
