I think a lot of modern construction sucks. My condo was built in 1980 and I almost never hear my neighbors. It is also a fairly well designed building where both vertical and horizontal neighbors have aligned spaces for sleeping eating and living. Along with side shard walls being used for closets and bathrooms.

My townhome is actually an old WW2 military hospital that got gutted in the 90's and turned into townhomes. I can hardly hear anything from outside since it was apparently built to survive bombing, but the walls between units allow a ton of sound through.

My apartment (what Americans would call a condo I think) was built in 2019 and I never hear a sound. Have tested playing loud music and I can’t hear it at all from the hallway. It just depends on how much the developers cared when they built it.
