ᐅ Renovating a Semi-Detached House or Demolishing It – While Still Using the Basement

NiriachHello!
We are considering purchasing an existing property. It was built in the 1930s and has a basement, which is also dry. However, the house is just under 100 sqm (about 1,076 sq ft) and quite cramped. It would require a complete renovation, etc. My concern is that the size might not be sufficient for our needs.
In terms of costs, I have a rough estimate of about 1500–2000 euros per sqm (about 140–185 USD per sq ft) for a full renovation.
The house has a basement, so the idea came up to continue using the basement and demolish the house above it in order to rebuild. I have read a bit about this, and I am also aware that demolishing a semi-detached house from that era is not straightforward. But if I am correct, depending on the plot, basement, and so on, it may be possible to do this.
There is no building plan available.
Could you take a look at this? Would it be feasible? Maybe even a tip on who could carry out such a project? Would this be significantly more expensive than a full renovation?
Of course, all of this only if the building authority approves.
Thank you

It was built in the 1930s. More likely much later. Such basic facts should definitely be clarified.
I see two issues that bother me: first, apparently a party wall shared with the neighboring unit, which will at least significantly complicate demolition. Second, apparently a staircase leading to a raised ground floor entrance, indicating that the finished floor level is considerably above ground level. Much more fact-checking is needed here. Honestly?

Of course, I meant a development plan—so not a specific requirement itself—sorry.
We plan to take a look at it tomorrow. According to the listing, the house was built in 1932.
The price to pay basically reflects the land value. It’s really fair, considering the location is amazing.
Yes, I also assume the shared party wall.
Do the following pictures help clarify?

We plan to take a look at it tomorrow. And yet you think it’s completely built over? — I take that as a sign that the floor plans for the other levels are also known. Then show them!

So far, I’m quite sure that’s not the case.

Gladly
The note about the top edges means that—in order to even consider whether it’s worthwhile—you would need to raise the ground level to install the foundation slab for the larger new house to be built there, correct?
I will definitely ask about the year of construction—which period are you thinking of? That would be important for asbestos, etc.
Built in such a way that I don’t really see the possibility of accommodating two children, an additional bathroom, and so on—that’s just due to the size, I’d say. 100 sqm (1,076 sq ft) is 100 sqm (1,076 sq ft).
