Calculation for a single-family house with 175m² living area, basement, and double garage

We are super excited about our new house with a basement. But that was already there, as we are renovating. My husband also says that a house without a basement is not a proper house. And we need/want a lot of storage space. But the basement costs really put me off. If we were to build again, there would definitely be a big discussion about that topic. I think I would rather try to manage without a basement and instead build somewhat bigger, because it is also more comfortable to have everything on one level. There are also partial basements, which I find interesting in principle. For example, only the heating and maybe a storage room go downstairs. However, I have no idea how much something like that costs and whether it’s worth it. It is called, for example, "Effektiv-Keller" at Glatthaar.

In the past, a cart without an ox in front of it was also not a proper cart. You can twist and turn it however you want: The most expensive (living) space is the basement room. From a young age, I have lived in houses with basements, before my current semi-detached house – with a basement. But that made sense there because without a basement, there simply wouldn’t have been enough space due to building boundaries, building height, etc. Does the basement have any characteristic that an above-ground floor does not also have? Well, it tends to stay cooler if you don’t have air conditioning. That’s about it. (And by the way, that is also the origin of underground construction, but it doesn’t date back to this millennium.)

Otherwise, for six years now, I haven’t missed the basement for a single day. The building services are easily accessible in the HAR, laundry is done upstairs, and the unavoidable storage space for things that you’d actually be better off throwing away is in the attic. The attic is currently not developed, but could be converted into living space for a manageable amount, and would then be a real highlight due to light, view, etc. Conclusion: No more basements, unless there simply is no other space available or creatable.

Edit: I consider the matter of a partial basement less sensible, because with that you only get a partial area, but in return literally bring a bunch of sources of error into the house regarding sealing, insulation, etc.

Well, it tends to stay rather cool if you don't have air conditioning.

But no one moves into a utility cellar to be able to sleep better in the heat. Or do they? If the money is available, then there is probably also money for an air conditioner. But you also mentioned two very important points why people build with basements: in the past, people had to store coal and preserve the harvest or not, storing it in a cool place. There was no KS yet. And if the development plan restricts the footprint so much that you cannot fit the required space. Personally, I also see a basement as sensibly designed for 3 children: fleet of vehicles, toys, playroom... the latter can also be well accommodated again under the noise protection.

In my case, yes, but not permanently, only on particularly hot nights.

Huiiii... that reads like tingling in the belly button

I would like to build with a basement, I have always envied all the friends who had their children’s room in the basement. I think my junior would feel the same.
also, a basement allows, for example, a separate room for sports.
my wife, on the other hand, finds basements creepy and would never spend the money on it. That is why we made the compromise that we will never build with a basement.
