Floor plan of a single-family house 155m², without basement, 3 children's rooms, 1 office

Hello,

But that is a picture from a sales offer. Is there also an official site plan that one can take a look at?

No, the 3D model and the floor plan are from me.

With or without the garage? With or without the base slab?

With garage (without door), without base slab/earthworks.

If that is allowed with QNG? The technology has to be inside the thermal envelope, and in an outbuilding it is naturally an effort with insulation and supply lines. For us, covering the supply lines with a slab would not be allowed.

Exactly, the construction company also said that the technical room has to be inside the thermal envelope, but that it would be possible.

You actually can hardly call that self-performed work anymore, because 95% of construction companies (including the well-known or especially the well-known ones) don’t include, among other things, the floor coverings in their turnkey offers. It’s the same with the remaining painting work. Nowadays, you already have to paint the stairs yourself, and the treatment of the roof underside is also no longer included.
Every company has its own description of construction services where you can’t see at a glance what is included in the "turnkey" offer and what is not.
The 3000€/sqm refers to a plastered standard house with plastic windows.

Thanks for the tip about the roof underside; I hadn’t paid attention to that so far.

And now to the design:
I would also place the house completely to the north, to have the garden on the south and west. For that, I would follow the slope’s course. Meaning: house with the ridge direction parallel to the street, as suggested in the sales brochure.

I’m now confused because of the sales brochure, do you mean the development plan? Or the picture from my 3D model? I assume you mean as shown in the attachment. Thinking about it, that makes a lot of sense. As RomeoZwo already said, the green strip provides some distance to the upper neighbor.

and then the living room with the rather sober possible furnishing.

Yes, I am also rather dissatisfied with the living room.

Thank you very much for your tips and the criticism

Is the upper building line at the same time the property boundary? You then have to keep a distance (3m?).

No, the green line is the boundary. Distance areas are according to BayBO.

As already suggested, the house should be moved further forward towards the street.

This is the maximum you are allowed to build.

Thank you for the visual preparation. That obviously changes everything.

Unfortunately, I just read that now. Then you can also use the image you used, if the house is only 8m wide.

The basis is that the plot is surveyed with detailed elevations (especially in the area of the house).

It needs to be clarified in advance what is meant by excavation and filling. Because the image at the bottom right then does not work.

Perhaps your interpretations of the development plan are also somewhat inaccurate.

Oh ok, maybe I shouldn’t work through the comments one by one but read everything first.

Thanks

Yes, that's often sensible. You can already mark passages you want to respond to in the meantime and "collect" them using the "+Quote" button instead of "Quote." Then you can insert them all into your reply or delete individual quotes from this collection if they might have become obsolete due to further posts.

Again, and in this order:

Here is the plot in the development plan

No, the 3D model and the floor plan are from me.

Of course, I am not asking if a floor plan or 3D model is a site plan.
I am asking if there is an official development plan or site plan because I assume you posted a picture from a sales offer in #2. Development plans rarely show reservation numbers of plots or examples of construction.

The image is from the official development plan, which can be downloaded from the [website of the municipality].
