Renovate or demolish a semi-detached house - still use the basement

Hello!

We are considering purchasing an existing property.
It was built in the 30s. There is a basement, which is not damp either. However, the house is only just under 100 sqm and completely built-up. It would need a full renovation, etc. My concern is that we might not really manage with the size.

In terms of costs, I have a rough estimate of about 1500-2000 euros per sqm in mind for a full renovation.

Now, the house has a basement. That’s why the idea came up to continue using it and to tear down the house on top of it and rebuild. I have done some reading on this and also have in mind that it is not straightforward to tear down a semi-detached house from that era. But if I have read correctly, it might be possible to realize this depending on the plot, basement, etc.

There is no building plan.

Could you have a look at this? Would that be possible? Maybe even with a tip on who might be able to realize something like this? Would it be significantly more expensive than a full renovation?

Of course, all only if the building authority agrees.

Thanks

Cost-wise, I have a rough estimate of about 1500-2000 euros per square meter in mind for a complete renovation.

That is too high! For new construction, you calculate from 2.XXX € - but that already includes the shell and the roof.

No construction plan is available.

And what do you call this basement drawing then?

This was built in the 30s.

Rather clearly later. Such essentials should definitely be clarified.

I see two things that I don't quite like: first, apparently a party wall with the neighboring half, which at least significantly complicates the demolition. Second, apparently a staircase to a raised ground floor entrance, indicating that the finished floor level is clearly above the finished terrain level. Much more fact clarification is needed here. Honestly?

"Considering" is the keyword

I obviously meant a development plan – so not a requirement as such – sorry

We want to look at it tomorrow. According to the exposé, the house was built in 1932.
The price to be paid is basically the value of the land. It's really okay – because the location is amazing.
Yes, I also assume that's about the party wall.

Do the following pictures help clarify?

We want to take a look at that tomorrow.

And yet you think it is totally built-up? – I read that as an indication that the other floor plans are also known. Then bring them on!

If realtors were shot for every mess-up... So far, I quite certainly don’t believe that.

Gladly

The note about the top edges means that - in order to even consider whether it’s worth it - the ground would have to be filled in to realize the foundation slab for the larger new house to be built there, correct?

I’m definitely asking about the year of construction - which one 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 2 children there, an additional bathroom, etc. - that’s just due to the size, I’d say. 100 sqm is just 100 sqm
