Is a basement always worthwhile in Baden-Württemberg? Due to the high land price per square meter

Hello everyone and best regards from the Ludwigsburg area (BaWü) :)

We are currently in the research phase on the topic of a single-family house in the above-mentioned area. And one point in the basic considerations is always the basement...
In our current (mid-terrace) house we have a basement, which I also use extensively with my hobby (milling and lathe machines, etc.). Of course, this was not always easy in the terraced house basement, as everything had to be disassembled and lowered down the stairs, but that is another topic ;)

So, you often read on various blogs, house-building sites, etc. very frequently that houses are often not built with basements at all, but rather a bit larger above ground, i.e., more ground floor instead.
The question of all questions that arises for me here is:

Does this statement even/also make sense in BaWü with square meter prices around 400,-?

At low square meter prices, I can imagine that, but here it seems quite expensive to me to have to buy the (half, due to 2 stories) basement area additionally? That alone is already a hefty amount just for the necessarily larger plot of land, and thus the space is not yet enclosed, roofed, etc., right?

Are there comparative prices per square meter for above-ground living space and underground?

Our desired house size would be about 150 sqm of living space, with ground floor and upper floor with full room height. And whether with or without basement, whichever is cheaper in the end.
Plots of land vary from 200-400 sqm

The basement should also have a residential-like climate (because of the machines and sensitivity to rust). Warmth is not the main criterion, but the associated humidity is. This should be stable and controllable. Does this require a so-called residential basement? I suppose yes. Does that mean a cost explosion as well? What scale are we talking about per sqm? Assuming a level plot

However, later on a large, fully insulated double garage (preferably double depth) is planned anyway, to also move the second hobby workshop located in the neighboring town (about 40 sqm) there.
But that can wait a few years, depending on the financial situation. However, it also needs its place on the plot...

Or does it already make sense to put everything on the ground floor at once and thus bite the bullet when buying the plot?

Please don’t be upset if I stepped into any obvious traps during this first visit, as I often have a sad talent for that :D

Many greetings to all and thanks in advance,

Marc

166 hits and no response, a fairly sure indication of a direct blunder, I suppose? ;)

Maybe it is also formulated ambiguously or with too much unnecessary detail...

Above all, I am interested to know if there are such guidelines for basement rooms as utility basements or living basements, like for example the often mentioned "2000,-/sqm built space" by the larger prefabricated house dealers?

With such matters, ideal conditions must of course always be assumed, meaning no ground problems, no pressing water, etc.

Hi,

so I assume your basement will be around 80-90 square meters.
For us, this size is just under 70,000€. It is a WU basement, the floor slab increase is included, but it is not a living basement. The costs for that are simply steep. I think that was another 40-50,000€ on top.

Just as a "reference value" for you.
But we have heard that barely any basements are being built nowadays.

Your question cannot be answered in a generalized way, which is probably why there have been no answers so far. It is also simply the case here in the forum that there are the "pro basement" and "contra basement" factions ;-)

You just have to calculate it yourself. If the land price per square meter is 400 euros where you live and you have "noise- and dirt-intensive" hobbies, then in my opinion a basement definitely makes sense.

Just roughly estimated: you want to realize about 150 sqm of "real" living space with 2 full stories. Consequently, your house will need a footprint of about 90-100 sqm exterior dimensions (depending on how large the hallway, entrance area, and stairs are. These are not counted as 100% "real" living space). To fully basement this area as a utility basement you can roughly estimate 50-60 thousand euros. If you have to/want to build a "Weisse Wanne" [white tank basement] it will be more expensive. A residential basement will also be more expensive.

Now you can consider how much more space you need on the ground floor and calculate it against your land prices. You also have to consider the development plan. Depending on the building area the floor space index varies. So if the property is 400 sqm in size, you cannot simply "build up" 250 sqm with house and garage.

Great, that already helps me a lot. Especially as guidelines, very welcome, thank you!

The difference between utility cellar and living cellar according to my latest research is that the living cellar must have the following "upgrades" (I hope this is correct):
heated
ceiling height of 2.5m
natural light through windows, not just light wells

I really don't need that. A properly insulated cellar (which supposedly must be done nowadays, is that true?) would already be enough for me without heating. For 10 years, I never had the heating on in our current cellar.
I would of course plan for heating capability, but full ceiling height and natural light I definitely don't need. Not even light wells ;)

Yes, at least 100sqm of outdoor space for the house was also my assessment.
50-60k for the cellar would be okay, at 70k it gets uncomfortable, 100k would be too much for me.
