Floor plan design for a new single-family house - 610 sqm plot - opinions welcome

How old are the children that they don't want to retreat to their rooms or like to sit in the dark? I don't know any 12-year-old who finds an airspace above the dining table so cool that he never wants to see the sun himself. And especially when the representative living area is as bright as a theater stage, it becomes all the more noticeable when you then enter a north-east room.

Or is there another building regulation requirement known to you that specifies the 5m?

It is at least stated in some LBOs. And unless otherwise regulated, this also applies. It serves to protect other road users, and why should one view it as reduced in some places?

Oh, that is quite a pleasant tone here with you! ... the positive criticism of some forum members really helps! Thanks for that.

Well, let's put it this way: you either don't respond to criticism at all or you downplay it. Also a way of communication, but one from which you will not benefit. Ask yourself whether you want to communicate here or if you can actually accept criticism. You wouldn’t be the first who only wants to present their house here.

It only strikes me as odd that almost all specialist publications do without the much-praised dimension chains here. So, no professional audience is present here after all?

You are not in a professional forum here, but rather a laypersons' forum. And precisely the lack of dimension chains (if that is indeed the case) should give cause for thought: without them, hardly anything can be viewed in a well-founded manner. Overall, only processes and orientation can be considered, but not dimensions, which do not play a minor role in draft floor plans.

Since I am new here, I am very curious whether there will still be serious and well-founded contributions.

Apart from the fact that no floor plans have been uploaded yet that can be viewed without downloading, the dimensions would likely be missing then as well.
I quite like the views except for NW. The question that arises: why not the garage in NW?

Is the garage allowed to be located there? Normally, it must be at least 5 meters away from the street almost everywhere.

If the gate can be opened electrically when approaching, generally yes.

The positive criticism from some forum members really helps! Thank you for that.

Should we read between the lines that you would not be grateful for valuable warnings?

What puzzles me is that almost all professional publications manage without the much-praised measurement chains mentioned here.

Please name (warning, without links!) such professional publications, I’m happy to learn more.

Since I am still new here, I am very curious whether there are still serious and well-founded contributions.

It is an open secret that only a ridiculous seventeen thousand of my posts are useful, and the ENTIRE REST (also four hundred and twenty, mind you) are actually ranting against clerks and bashing brokers *shame*; unfortunately, from , the king of serious and well-founded contributions, there are no more here, and none from either. Recently, has unfortunately left us. Well, the air is getting thinner. But in a free country, it’s up to you to decide whether you want to put a bowl with measures in front of the remaining members of the community or not.

not wanting to retreat to their rooms or liking to sit in the dark?

- We have a ratio of window area to NGF of 27.86%, the Lower Saxony Building Code requires at least 12.5%, whereas DIN EN 17037:2019-03 assumes optimal lighting at 20 - 25%. In addition, there is light in both rooms from two different cardinal directions. I am happy to consider the idea again. The air space was one of the most important points for us in the planning. Unfortunately, you cannot orient everything southwards in a plan.

is at least stated in some state building codes

I believe there is no corresponding clause in Lower Saxony. Here 0.5H applies.

why not the garage in the NW?

- Garage positioning: due to the utilization of the plot in connection with the sun path. A maximized garden area is to be created facing south. With the garage in the east, we would only have proper sunlight in a garden area at least 6.6 m wide from the evening onwards; in return, the kitchen would border more closely on the neighboring building.

What more is there to say? You argue with DIN standards for window areas, to you the most important thing about the house is an air space, which is basically just architectural showmanship that has so far been reserved for architecturally well-designed villas - that north light is always cool and in winter during bad weather rather grey-blue daylight… whatever. It's more important to you to have a bright, light-flooded dining and master bedroom area than to equip the children's work and living spaces with psychologically positive lighting conditions. I had a northeast room and except in midsummer with good weather, I always had to work or play with artificial light in the room. For me, the weighting is not right there.
