Hello everyone,
We are building a single-family house with a developer.
We are currently in the design phase.
In the first draft of the house, some questions came up, and maybe you can help.
1. The plot is quite narrow, so the first design has no roof overhang (to make the house as wide as possible) ==> the gutter is basically right on the wall.
Is this acceptable, or is it better to include a small roof overhang (30cm (12 inches)?)
What is the purpose of a roof overhang anyway?
2. The walls on the upper floor are planned to be only 12cm (5 inches) thick and made of gypsum plasterboard/drywall.
I’m now worried that these thin walls will hardly insulate against sound. In other words, that you’ll hear every little noise from the neighboring room. I want peace and quiet and to be able to have a conversation without everything being audible.
Are my concerns justified?
Which walls can we use to achieve good sound insulation? Brick walls?

However, I also fear that the soundproofing will not be particularly good.Sorry, but such ignorance should not be published in the "signature".. it only unnecessarily confuses someone with no building knowledge.
You don’t have to know everything.. but in that case, it’s better to simply refrain from giving such answers!

How thick should the walls be for good sound insulation?
The builder now wants to install 10 cm (4 inches) or 12 cm (5 inches) thick walls... is that sufficient?

That simply depends on your requirements. If you have increased sensitivity, the wall must be adjusted accordingly!
You can see examples of this on the websites of companies like Knauf, Rigips, or Fermacell. Go to the "Sound Insulation" section, and you will find the wall options they offer along with their respective values. It is also clearly defined what specifications each company requires to meet their calculations—that is, to achieve the specified sound insulation rating.
You can then provide these specifications directly to your general contractor.
