ᐅ Basement versus Increased Living Space on the Ground Floor

Dear all,
We are planning to build a bungalow with 3 rooms and about 85 sqm (915 sq ft) of living space. Since the plot is on a slope, we need to build with a partial basement.
Which option would likely be more cost-effective:
1. Living area on the ground floor (including a guest room) of 85 sqm (915 sq ft) and a 50 sqm (538 sq ft) basement used mainly as a utility cellar with a technical room (then we would only need one bathroom).
2. Ground floor only 75 sqm (808 sq ft), guest room in the partially finished 50 sqm (538 sq ft) basement as living space (which would require a second bathroom but could be fitted out later by ourselves).
As soon as the basement is meant to have living space, the access routes must be heated and insulated. Also, an internal staircase is necessary. A purely utility basement could possibly be accessed only from outside without an internal staircase, saving space.
Theoretically, a room on the ground floor requires about 12 sqm (129 sq ft). If this room is located in the basement, additional space for stairs on both floors and another hallway is needed, approximately 24 sqm (258 sq ft).
Am I thinking about this correctly?
Has anyone calculated a similar case before?

To start thinking about how you can arrive at an affordable solution, it’s important to check what the zoning plan says and what the site plan indicates regarding the blue line or property boundary. It looks to me like there is only a building zone?
However, you still need to know if there are any restrictions. Unfortunately, I don’t have more information; the new development area has not yet been fully surveyed.

I’m a bit puzzled by the comment “or is the budget already too tight for a ruler” – what’s that supposed to mean? If you’re worried about my financing: thanks, but that’s not necessary, I don’t need to take out any more loans.
Regarding the property marked by finger on the photo… unfortunately, my phone doesn’t have more advanced tools.
I don’t have detailed documents yet, as the extended soil survey is still pending and the building plot hasn’t been finally measured. At the moment, I’m planning based on the zoning plan and the drawing I already posted here.
But that doesn’t necessarily relate to my original question. Sorry for the irony. I probably forgot to add a winking emoji 😉
If you think that’s unrelated to your question, then what else could it be besides the slope and your roughly marked property boundaries?
I have concerns about your planning since the slope is not exactly uniform. I would gladly prepare an overview with property boundaries and contour lines, but I lack reference points. So unfortunately, I can’t assist with that.
What does the geoportal say about the property boundaries?

Why? The plot is suitable. Just build a basement under the bungalow, done. There wouldn’t even be any discussion for me. Go to a turnkey provider, get a detailed cost estimate. Then you have a number. Then ask how much filling in costs. Then you have another number. Compare them. Done. I thought the same: a bungalow with a basement underneath. But I would like to hear experiences regarding which is more cost-effective: a partial/living basement or a purely utility basement with a larger house footprint.

If you think this doesn’t relate to your question, then what does – the slope or your inaccurately drawn property boundaries?
I have concerns about your planning because the slope isn’t evenly graded. I would gladly prepare an overview showing the property lines and contour lines, since I lack reference points. Unfortunately, I can’t help further without those.
What does the geoportal say about the property boundaries? Unfortunately, it hasn’t been surveyed yet. But from my roughly drawn outline, you can already see that the slope does not run evenly toward the northern boundary, but rather diagonally toward the northeast.
