Build a terraced end house with an additional unit (GÜ) on your own

Here all beams with 11.5 cm sand-lime brick plus 2 cm fire protection are used.

Thermal insulation is unnecessary since the other side is not an exterior wall.
Sound is basically not reduced by ETICS. Simply use 20 or 24 cm of aerated concrete toward the neighbor's side and then it's quiet.

Thank you. I thought in this regard, "more is better."

The city simply assumed a sense of proportion and reasonableness on the part of the builders, which cannot be assumed for all builders.

However, the municipality would probably have been better off designating rows with basements and without basements from the start. Such a mix certainly had to cause trouble.

That would have been the minimum, but I went further for good reason. Even a normal row of terraced houses (i.e. without the municipality developing the facade) has far too many interfaces for uncoordinated planning to be justifiable.

Honestly, 11ant, like many others, advised you from the beginning not to build there.

Please quote me more precisely. Where exactly was I supposed to have advised to build there, to my recollection, I have always linked any encouragement to the OP with warnings from the very beginning, about the dangers arising from naive planning participants and always unconditionally issued the motto "one planner per row". Today I know better how devilish the devil can be like a squirrel and will henceforth add "and no start of construction before completion guarantees for the entire row are in place."

Probably a dummy question, but I don’t understand what is wrong with an additionally thick wall and insulation in a row of terraced houses. Isn’t more wall and insulation a great thing because of soundproofing?

I thought in that regard, “more is more.”

An overdose is always harmful, the saying "too much of a good thing" applies. Where a warm room is adjacent to another warm room – to quote the late Grandpa Willy (incidentally a civil engineer) – insulation is “unnecessary like a hernia.”

I am so sorry about that. He will make your life a living hell if he stays living there. Especially considering that the mentality often demands a lot for itself. Our immediate neighbors are also of Turkish descent. I could tell you a thing or two about what they think of consideration. There may be others, but unfortunately, they don't live in our area.

Our direct neighbors are also of Turkish origin. I could tell a story about what they think of consideration. There may be others, but unfortunately, they don’t live in our area.

In my experience, Turks of the "first guest worker generation" highly appreciate German order and, as Her Majesty E2R would say, are "not amused" by their compatriots from the "no consideration for unbelievers" faction. Therefore, if your "dear neighbor" persistently lacks manners, a conversation with their imam (or uncle) can actually help; both are "authorities" and moreover brothers in faith, where this silly talk of "pretending rules don’t apply to me is part of my cultural identity" doesn’t work. Calling the traditional costume group instead is almost like going to a knife fight armed with a pistol (which only sounds better at first glance).

Unfortunately, the father, with whom one could have a good conversation, passed away a few years ago. The wife still lives there with 2 sons (grown up) and 1 grandchild. They are all loud, but they think they are great neighbors and love the peace and quiet. I couldn't help but tell him that it was quiet before they moved in. They are nice, I can't say otherwise, but they just have a different understanding of quiet at night than the rest. They are Kurds, is the Imam worthwhile there? Regarding the uncle, he participates in the nightly noise. We will probably install a waterfall fountain in the garden and an air conditioner for the bedroom in due time. But I am not afraid of confrontation either. I just feel sorry for the original poster because I know how neighbors can be, and ours may be inconsiderate but at least still nice and probably don't really want to make my life hell on purpose. They just don't care.
