In Germany, fully underground full floors are irrelevant,

You omitted that the original poster wants to expose the basement where it would be below ground for a driveway, so that only the northwest side would have something like a ground-level house entrance – the rest would be the building envelope.

Worse: ramping up in a curve from the uphill side street. Naively thought.

and above all, to invest your money in something permanent with a clear conscience instead of constantly paying rent, which is a long-term loss.

Absolutely not! That is really the only reason why you should not build.

You will never live as cheaply as in a self-built house – the other reasons you mentioned have to be worth it to you. After all, you only live once.

But please don’t think that you can expect lower long-term losses than with renting.

Especially not with that difficult plot of land and the necessary groundwork involved.

You have a logical error—you want to overcome the height difference with a 90° turn from the street, which will be at least 2 meters (6.6 feet) higher than the ground level of your basement within 3 meters (10 feet) plus space in front of the garage.

I had also posted a floor plan example with enough level space, which could be clarified further—whether a walk-out basement with one story is possible.

By the way, why do you need such a huge office for family use?

It doesn’t necessarily have to be within 3 meters (10 feet); we have enough space on the property to make a longer but shallower driveway if needed. Yesterday, we looked into the option of having the garage next door. Let’s see if I have time today to tinker with that idea; it would then be with a partial basement only.

One story plus a walk-out basement would of course be allowed; lower is always possible. However, my husband is concerned that if everyone around us builds two stories plus walk-out basements, we would be the “lowest,” and the neighbors might block our southern sunlight. I could imagine using the walk-out basement partly as a living room/dining area/kitchen.

Currently, our “office”—actually the second bedroom—is the main living area. We both enjoy PC gaming, and my hobby is digital drawing/design as well as watching DVDs on the PC. That’s why we want it to be relatively large since we spend most of our free time and hobbies there. Also, a big basement is important because my husband is passionate about working on his three motorcycles/mopeds 🙂 In case of illness or old age, having an extra room on the ground floor (without stairs) would definitely be useful for simply placing a bed later on. We don’t really want it to be smaller than 15 square meters (160 square feet).

A partial basement makes little sense on a slope, and I would always want to access an underground garage from the valley side. A comfortable ramp has a flat length of one car above, a flat area in front of the door at the bottom, and only a 6° (10%) slope in between — so for a 2 m (6.5 feet) height difference, the total ramp length is about 30 m (98 feet) — and it’s straight. Approaching the garage from the uphill side would be too much for me. With a 5 m (16 feet) width, that would be 150 sqm (1,615 sq ft) of floor space.

So, I have let some time pass (unfortunately, we still don’t have an appointment with the architect; I’ve already tried to arrange one).

The whole thing with the upper floor and setback was a bit challenging to plan, so I have now tried a version with a daylight basement and only one story. A big question mark remains, of course, regarding whether the garage will work the way we want it to, and how much it will cost if we do it like a "basement garage." In the end, the garage will cost us a lot no matter how we build it. Because if it’s upstairs, it probably still needs to be basemented due to the slope, or built up with a retaining wall. I think both options will be quite expensive.

We both actually really like the current design. What do you think about it?
The two windows in the living room would only be small basement windows here; by then we should be partially out of the ground to be able to do small upper windows there.

We might want to make the garage/workshop smaller as we come to quite a few square meters overall. I would be interested to know if this design is more expensive than the previous ones with 2 stories plus basement. Previously, it was about 100 m² basement + 100 m² ground floor + 50 m² upper floor; now it’s 150 m² daylight basement + 90 m² ground floor, so roughly the same area. Are there still cost differences? Is building "up" more expensive than building "wide"?
