By southwest? Deal with the sun path. There is a website... there is always a difference... but not during terrace season. Some things are overrated or underrated there.
You will have light. Unless you want to sit there at night
The terrace also has its justification by the kitchen in the evening, since you sit there, grill, eat, and drink.
I assume a hedge. I also assume the use of the "front garden."
The plot goes through a developer!
I have already dealt intensively with the sun path. Maybe I am overestimating it...
Positioning the terrace by the kitchen is definitely the best. I also learned that from you. But what would be so bad if the terrace is by the living room? If the kitchen directly adjoins the living room, it is not so bad for me.
Did I overlook an answer, or is my question whether an offset shed roof is also permitted still open?
Do you really want a hip roof explicitly, or is it just the fear of the plainness of the gable roof that is the reason for the thought?
At the risk of repeating myself: in terms of sound insulation, the workmanship—especially: the execution of all connection details—is much more important than the sheer mass of the building material.
Is it even possible to have an attic with a shed roof?
I find a hip roof prettier. But I am also open to compromises. If I understood correctly, a gable roof is significantly more practical in terms of additional space under the roof. So the question is, appearance or function?
I know your opinion. I oppose it. From my own experience—having lived in more than 10 apartments/houses. Aerated concrete is louder. No problem for two people. From three, it would be annoying.
I have already dealt with Poroton vs. aerated concrete vs. sand-lime brick but am still rather undecided. The developer offers Poroton as standard with ETICS on the outside and probably Poroton 11.5 on the inside.
It does not have to be the best of the best regarding soundproofing. A good Poroton insulation would probably suffice for me.
With the disco system and the fear of washing machine noise, it will probably come down to sand-lime brick. Have you already had a general contractor, and would he even offer that?
You see that wrong. I myself am actually not so noise sensitive. But why should I ignore the topic of noise when building a house? It is an important topic, and I am willing to invest a few euros more for it. It must, of course, remain within reason.
I will also continue to express all (currently very many) wishes first. Whether you get everything in the end is another matter.
