Floor plan design: Single-family house with 4 bedrooms and an office, 160 sqm

It would be even better if the inventory could be seen unobstructed. Forgive my harsh tone from earlier, we currently have (again / as often) several questioners in parallel here who delay their getting-help-ability with dripping foundational info).

Oh, Berlin, then you can check live with . Read my avatar carefully and get in touch, then I will gladly bring you together. But Berlin is big and may have as many diverse building authority opinions as district offices.

I covered the inventory because you can hardly see anything in the section. The property was quite overgrown and on the satellite image you only see a green tree canopy. Here is a picture after everything was cleared.

Now I have already been summoned twice, so I will briefly say something about it again:
I would indeed recommend to everyone the two changes: no longer building with GU/GÜ and preferring a gable roof (preferably with stud rafters) over a hip roof.
If I could build again with my experience, I would change a few more things for us, but those are very individual and depend on preferences/daily habits.
Just for us, I would now plan a closed kitchen, it has become clear that we often "hang out" separately in the evening and the kitchen noises bother us too much then.
The side entrance door in the utility room has almost never been used by us, which is also related to the fact that we haven’t finished the parking space yet. With this I want to say that you can paint it without worries and rather use the wall as storage space.
I would actually have mirrored our house, meaning utility room and kitchen towards the street side.
I would have planned fewer/smaller windows, they are not appreciated and for half of them the shutters/venetian blinds are also down during the day in winter.
I would have placed the door of the middle room on the upper floor a bit asymmetrically so that one can act more flexibly with wide furniture.
In the bathroom, on the bathtub side, a drywall construction definitely should have been installed both for insulation and as a pipe duct as well as for storage.

Technical small things: outdoor sockets not switchable but protected with a higher fuse and at every corner/side of the house.
A few more three-way switches in the hallway/staircase. Switchable outdoor light in front.
Ventilation planning with supply and exhaust air in the rooms, because the doors are always closed since the poodle cannot behave (yes, it could probably be solved with better training, but we are too incompetent) and the necessary overflow openings then lead to too much noise transmission.
Overall, pay more attention to internal soundproofing (filled Poroton bricks or external aerated concrete and internal KSS, wood fiber insulation boards for sound insulation under the screed).

All in all, however, this is all just complaining at a high level, the corrections mentioned above would probably have been more expensive in many cases, the house is absolutely livable and we are even satisfied.
I won’t get a viewing approved by the government, but I’m happy to answer questions.

I can't get an inspection approved by the government,

I know that, and was thinking more about the outside, and about chatting with you informally like in this post.

The side entrance door in the utility room has almost never been used by us, which is also related to the fact that we have not yet finished the parking space. What I want to say is that you can paint it without worry and then rather use the wall as storage space.

I would not generalize on that point. We have it too and I definitely don’t want to miss it. We use the side entrance door more often than the front door. At least when we are at home (and we often are, as retirees). Short distances to the laundry area to hang the laundry directly from the washing machine, short distances to take out the trash (bins are located at the laundry area). Short distances to the garages and the shed, where garden tools etc. are kept. Store large purchases directly in the utility room. Coming in from gardening and being able to wash your hands immediately (the sink is located right next to the door). Space for work clothes and gardening shoes where they are needed.

Yes, definitely, this is specifically tailored to my floor plan, additionally with the restriction that we do not use our parking space. But it is not a must-have (otherwise we would have changed something by now).

Now I have already been summoned twice, so I'll quickly say something about it again: I would actually recommend the two changes to everyone, not to build with GU/GÜ anymore and to prefer a gable roof (preferably with a studio truss) over a hip roof. If I were to build again with my experience, I would change a few more things for us, but these are very individual and depend on personal preferences/daily habits. Just for us, I would now still plan a closed kitchen, it has turned out that in the evenings we often "hang out" separately and then the kitchen noises bother us too much. The side entrance door in the utility room has hardly ever been used by us, but that is also related to the fact that we do not yet have the parking space finished. What I want to say is that you can safely omit it and rather use the wall as additional storage space. I would actually have mirrored our house, that is, utility room and kitchen facing the street side. I would have planned fewer/smaller windows, they are not appreciated and half of the roller shutters/blinds are down even during the day in winter. I would have placed the door of the middle room in the upper floor a bit asymmetrically so that you can be more flexible with wide furniture. In the bathroom, there definitely should have been a stud wall construction on the bathtub side, once for insulation and pipe installation and also as a shelf. Technical little things: Outdoor sockets not switchable but rather secured higher and on every corner/side of the house. A few more intermediate switches (3-way) in the hallway/staircase. Switchable outdoor light in front. Ventilation planning with supply and exhaust air in the rooms, since the doors are always closed because the poodle cannot behave (yes, it could probably also be solved with better training, but we are too incompetent) and the necessary overflow openings then lead to too much noise transmission. Overall pay more attention to internal sound insulation (filled Poroton bricks or exterior aerated concrete and interior KSS, wood fiber insulation boards for sound insulation under the screed).

I can't get a viewing through the government, but I am happy to answer questions.

Thanks for the feedback from practice. The I-shape of the open space has been mentioned here quite often. Besides the noises, does anything else bother you here? - thanks again for the inspiration with the rotated floor plan. Do you still see a chance to achieve something similar if you keep the old orientation?
