Build a new 350m² single-family house in Wandlitz

That is stated in #4

It will be the same as in all fields, whoever does not deal intensively with the individual trades themselves, and that is only possible if one has a solid technical understanding and the factor time is also available, must have an experienced professional at their side.

I would really like to discuss directly with a neutral expert for energy production, heating, electrical, shell construction, etc., and create a corresponding precise specification of services.

Only when these detailed service lists are roughly established does one look for the contractual partner for all the then necessary work.

So next up is the search for the neutral experts :)

Good night!

AND WHAT IS BAD HERE ETC.?

You don't have to copy anything in twice here. It only contradicts what you then write here. Also, your first post suggests that it’s about your/your house (with your wife). ... But oh well... you don't kiss trolls, and it also has absolutely no added value here as long as none of it will be seen.

:D here is the troll at home. After he has shown his true face, this thread can actually be closed.

Now I had hoped to find details about a rather interesting project on 10 pages, to see well-planned floor plans or similar, to learn something more, and was immensely disappointed. This thread is pure waste of time.
