Hello dear ones,
Thank you so much for all the answers!
We have received some information in the last few days. The houses were built as 2 independent houses that are additionally soundproofed with insulation on the shared side. According to the city, the plot is not one property but 2 independent, legally separate plots.
The outdoor area was planned so that the terraces are not next to each other but on the far left for the left house and on the far right for the right house.
The house has 125 sqm of living space on 2 levels plus a full basement, and the plots are 325 sqm and 360 sqm in size.
We have an appointment with the construction company next week, and we have already received the exposé in advance.
Currently, only the shell and windows are in place, but no screed, stairs, etc. that is still open. You can see the bricks and pipes, etc. are not laid yet.
I only have exterior pictures so far if that helps.
Regarding noise protection, you have already helped us a lot. Thank you very much for that! Now we only need to clarify whether a wall between 2 children's rooms on the upper floor could possibly be moved. We would also like to have the washing machine and dryer on the upper floor and not in the basement (as planned in the exposé). The question is whether such a change is still possible.
We currently have a masonry staircase here in the rental house and would like to have one like that in the house as well. Are there any advantages or disadvantages to a spiral steel-wood staircase?
What would you definitely discuss with the construction company in relation to the already existing shell and basement (I have already noted fire protection, insulation) since the shell is already standing?
Best regards
