Hello,
we have found a house that we would like to buy.
It is a semi-detached house built around 1965, constructed with solid masonry and fully basemented.
According to the building description, the interior walls/fire protection wall are made of limestone. These are plastered and covered with woodchip wallpaper.
According to the original architectural plans, the wall between the two semi-detached units is 24 cm (9.5 inches) thick. Floating screed has been installed on the floor.
How would you assess the sound insulation towards the neighboring house?
We are concerned that the soundproofing might not be sufficient.
Thank you very much.

24 sand-lime brick is the best thing that can happen to you regarding sound insulation! That’s simply not true in general. It doesn’t help at all against impact noise; decoupling is the only effective solution there. And I don’t see that here.

Unfortunately, this cannot be seen in the architectural plans. To me, this looks like a classic single-leaf party wall, which was generally common at the time – even up to ten years later, it was still widespread in terraced houses without depth (or height) offset.
However, my main concern here would not primarily be sound insulation: thermal insulation, heating system, water pipes, and windows would be higher on my checklist.
A build year around 1965 certainly doesn’t mean "old building," but it is already in the caution zone regarding underestimated costs for modernization.

A brief overview of the house...
The gas heating system was completely replaced 3 years ago.
The windows are double-glazed and made of uPVC.
The roof is about 10 years old.
We would replace the water and electrical wiring ourselves, including new bathrooms.
However, the primary concern is the noise from the neighbor and whether and to what extent it can be heard under the current conditions.

But primarily, it’s about the noise from the neighbor and how much of it can be heard given the circumstances. You won’t hear the squeaking of the marital bed, but you might hear temper tantrums (probably those involving broken furniture). You won’t be woken up by the neighbor’s toilet flush. Unless they are a drummer in a heavy metal band, I would be relaxed about it.https://www.instagram.com/11antgmxde/

When I’m outside in the front yard, I can hear the neighbor disciplining their child – bear in mind, these were detached houses with a 3-meter (10-foot) distance to the property line.
I once heard that a basement can block a lot of noise. One element to check is the staircase. You will always hear piano playing, and it’s very likely you’ll hear furniture being moved as well. I myself lived in an end townhouse.
If a neighbor coughing bothers you, avoid semi-detached or townhouses, because you will have neighbors who make noises just like you do. Sound also tends to carry voices and noises from house to house along a row.

Additionally, the house is fully basemented and features a floor slab with a waterproof membrane.
We have another appointment with the seller next week. Maybe he can provide us with some information about the soundproofing.
Is it possible that the house still has an expansion joint that was simply fully covered with brickwork so that it is no longer visible?
Is something like that possible, or does the expansion joint always need to be visible?

Could the house still have a separation joint that is simply fully covered with cladding so that it is no longer visible? I would be more likely to believe in the stork. That would be a sound bridge and also prone to cracks. It’s very unusual.
