I once drew something like that. Doesn’t quite fit your plot. Also has fewer m2 than YOU want.
First of all: Awesome floor plan, cool house!
My hillside house. If I get a suitable plot. But here the open space is upstairs. [ATTACH alt="Beispiel1.JPG"]61633[/ATTACH]
That probably won’t please many here who basically question everything – I quote roughly: "Is that a 1.5-story saddle roof house with a basement stuffed underneath where I’m supposed to sleep?" and "How do you want to get yourself a cold beer standing in the garden?" – "Do you always want to walk up the slope?" and so on and so forth.
I generally notice that a few people here, as soon as they hear hillside, exclusively entertain the idea of a two-story house because that’s so great. I also find it funny that it’s always the same approach: OP posts their idea including budget. Then:
A) The budget is already fundamentally torn apart. "That won’t work" "Way too little" etc. Once that is done, realistic assessments come.
B) In case of hillside location, pushed toward bungalow. A suggestion like here gets torn apart, see above.
So now something helpful for the OP: We’ve gone through the process – prefab house providers, general contractors, etc. The problem is that most will first present you with a standard design (for flat plots), and the salespeople only think about selling. That doesn’t help you. I (and I assume you too) simply don’t want to sign a 450k contract, feel secure, and then when the excavators arrive the GC says "OH, that’s a hillside, we need more money here and more money there," and so on.
Here’s an alternative:
How about someone professional going to the plot with you and planning your dream house (affordable) together with you? If you plan the hillside from the start and design something really awesome? If you had a cost estimate that is reliable?
My tip: Look for an architect/engineering office that is not tied to house manufacturers. However, I think there are already some GCs who know about hillside construction.
