ᐅ Demolition / New Construction / Renovation / Building on Existing Basement – Ideas & Experiences?

As I have mentioned in several places, we purchased a plot with a small settlement house (semi-detached house) from the 1950s on it.
The house is about 90 m2 (970 ft2) in size and is presumably partially basemented.
The other semi-detached house, to which we also need to extend, does not have a basement.
This means that if we demolish the basement, we would probably (?) have to carry out underpinning, which sounds costly and not entirely straightforward.
Therefore, we have now considered whether it might be "easier" to only demolish the house but keep the basement and build a new structure on top of it.
Alternatively, we could renovate the old house and add an extension (although this might again cause issues due to different settlement behavior?).
We would not build only on the basement area or the current house footprint, but want to expand significantly overall (approximately 200 m2 (2,150 ft2)).
So now my question is about experiences with building larger on an old basement?
Has anyone done this here? Is it even possible?
Is there any other option besides having to do underpinning when demolishing? (I originally thought that you could simply fill in the basement, but apparently that is not possible (?)

Is there a development plan? Often, the roof pitch must not differ from that of the neighboring half of the house, as the existing buildings also show.
I would rather consider an extension and renovation. No, there isn’t one.
In the area, there are quite a few creative solutions for this “preservation of the settlement character”…
There is everything from Tuscan-style villas to flat roof and gable roof combinations.

Yes, that is probably the case here as well.
At least for the neighbors, it was only one wall. You should first arrange an inspection with a structural engineer. As interesting as the question of how to reuse the basement is, the top priority is that the neighboring house survives your demolition without damage. The necessary measures for this will define your options for the basement.

In any case, it was just a single wall on the neighbor’s side.To be honest, I didn’t understand this statement: if the shared wall on the right side is single-layered, then from the left side the same wall can’t be double-layered either (???).https://www.instagram.com/11antgmxde/

Smialbuddler16 Oct 2021 19:24@11ant I had interpreted this as "at the neighboring semi-detached house," which might have been built at the same time or similarly. But you’re right, asking for clarification makes sense.
