Costs partial basement vs. full basement

From a structural perspective, I would personally only build a full basement or no basement at all (= slab on grade over the entire area). With today's technologies, you no longer need huge technical rooms. Four by three meters are more than enough, possibly as an annex on the north wall with a small roof, as an extension.

With a partial basement, overlaps can bend and cracks can form, as there is always an offset/disturbance from a structural standpoint. If you excavate the partial basement and do not properly compact the gravel layers all around, the material will settle.

Personally, I would not build a basement at all anymore. Throw everything away and store nothing anymore. The days of hoarding mess are over – in the future, you will have to pay about 5 euros per kilogram of waste – so get rid of everything that can be discarded.

For tools, a 3 x 4 meter room is sufficient. In old age, you won't need many tools anymore anyway.

I will dispose of cars anyway in retirement because they are totally useless – similarly, repairs will no longer be necessary. Better to travel by train and bus – Europe-wide!

Yeah, right... creepy figures sometimes stop here

Yes, sure... creepy characters sometimes stop here

Their nickname says it all... no arguments, only spam posts for a few months.... Don't they have any other work?

Nah, it's all overrated – when you're older, you don't need that anymore. Oh yeah, arguments? Do weird future visions really count?

No, it's all overrated - you don't need that when you're older.

Oh yes, arguments? Do really strange visions of the future count?

Good day Lexmaul79. You seem to me more like quite a "funless" person..... ? ... ( you have to take it lightly )

ps. Cork is no longer installed today! In general

In my experience, once you enter "retirement," you suddenly need a lot more tools and hobby space (where of course the vacant children's rooms come into play), and the car also gets used properly again. Putting that aside, I also cannot understand why a full basement should cost 40k more than a partial basement. It can't be just the bit more concrete for the side walls and floor slab. The shell construction for the entire basement almost costs less than that. If the architect is, of course, calculating a full interior finish as living space with high-quality equipment, it might make sense. And my gut feeling tells me that this is creating a nice source for construction defects and later damages, especially since nowadays we no longer build with flexible thick mortar joints and massive, soft clay bricks but the hardened stones are virtually glued together directly.
