Build a new house on an old cellar

If we want to use the settlement house for residential purposes, however, a lot needs to be done.

1. The roof is from the 50s and is not insulated.
2. The facade is made of 30s pumice stone and would need to be insulated.
3. The ceilings are creaking wooden beam ceilings, something would have to be changed there.
4. The electrical and water lines would also have to be redone.
5. New front door....

So the question would probably be, what condition is the settlement house basically in otherwise? Otherwise, here are the thoughts in order:

Regarding 1: If the condition of the roof structure is good, that should certainly be possible. Ok, you have to see whether you can insulate as required or whether the roof structure cannot support this. Otherwise, new roof structure, but that would also be feasible.

Regarding 2: That should be quite manageable for a craftsman and is usually also required in a new build.

Regarding 3: Do the wooden beams creak? Or rather the probably laid floorboards on top? Those can be replaced, I have done that myself in my house from 1900 including height adjustment.

Regarding 4: Depending on the construction of the house, that is also not a problem, and especially in the unoccupied state you can work more freely.

Regarding 5: That should be the least problem!

I would definitely look at how the building fabric is and whether the layout of the rooms otherwise fits. If that is the case or can be implemented with not too much effort, I would renovate.

Hello,

Regarding 1. The roof truss is quite eaten up by woodworms. Although it seems that no more damage is occurring, some beams are quite deteriorated. The spaces between the beams are filled with Bissteine.

Regarding 2. yes, you are right.

Regarding 3. in one room, the entire ceiling vibrates when someone walks upstairs. It is a very beautiful parquet floor glued down, so I am hesitant to tear it out before I have made a decision.

and whether the layout of the rooms fits otherwise.

That would be my "main argument" on the table page "against new construction": that the need regarding the rooms of a future adult-child apartment can hardly be defined yet.
