ᐅ Adding a basement beneath a double garage to save money

I had a conversation yesterday with a developer who suggested that I could skip the basement under the house and instead build a small cellar beneath the double garage. The double garage could then have access to the house. He will provide a cost comparison later.
From my research, creating a cellar under the garage costs between 20,000 and 30,000 euros. If I can have a basement under the house for 20,000 to 25,000 euros more, I find that option more practical.
What are your thoughts on this?

Why do I want a basement? I have often asked myself this question:
- I enjoyed it as a child, ...
- All my friends and acquaintances say, ...
.....So the next car just won’t be a BMW but a Japanese brand instead...
...However, these arguments are the weakest. If you had said that you need the space... think about that!
As for the last sentence, all I can say is: if it makes you happy...

In the end, I hope that a basement with 40m2 (430 sq ft) of usable space will cost no more than 50,000 euros. 40 m2 (430 sq ft) is a very typical size for a full basement—at least when you count only the practically usable area. The remaining space is then labeled "hobby room" on the floor plan.

Wallpapering is really not that difficult, and you don’t necessarily need a company to sow the lawn. This way, you could save some money.
You can then invest that money well into the basement.
If in the end you decide on a basement under the house, try to build the outside stairs and the basement door aligned as much as possible.
In our case, as is probably common, when you reach the bottom of the stairs you have to turn about 90 degrees to face the door.
A few years ago, I bought a lathe. I didn’t choose it based on the technical specifications but rather on the size that I could still get upright through the door. Having a door aligned with the stairs would have been really useful because then I could have brought it in lying down, and it might have been a different model.
I would also recommend a small room as a storage pantry. Ours contains not only preserves but also flour, sugar, canned goods, and even the chest freezer, since it stays around 12°C (54°F) there all year round.

Initially, we also planned to build without a basement. However, our perspective has changed over time.
Due to our plot having a slight slope (about 1.5m (5 feet) diagonally across the house area), the general contractor quoted us an additional cost (foundation footings) of around €10,000 for the slab foundation. As an option, a 65sqm (700 sq ft) full basement was offered as a "finished variant" for €35,000. If I offset the necessary foundation footings, that leaves about €25,000 extra for the basement. It is certainly not fully finished, but acceptable for technical equipment, a utility room, and storage, and can be further developed later if needed (possibly an office or similar). Additionally, we can reduce the living area from 150sqm (1,615 sq ft) to 130-135sqm (1,400-1,450 sq ft), so the difference is minimal.
A partial basement would have been sufficient for us as well, but it doesn’t save that much and has technical disadvantages (wall accessibility, house settlement behavior). We also considered a basement under a double garage, but that option is not much cheaper than the one mentioned above and is less valuable.

In decades of experience with a partial basement (on a level plot), I have not observed any problematic settlement behavior.
