Planning 130 sqm single-family house on 500 sqm plot

My guides should actually still be pinned at the top on the topic of placement of the house or starting the planning. For such a medium-sized plot, I would draw everything around it. Everything. And nicely with a pencil, so that you can still see later what you have already tried out and erased!

On the topic of parking spaces arranged one behind the other. I have found no prohibition against placing parking spaces one behind the other neither in Paragraph 12 of the Baunutzungsverordnung nor in our development plan. In another new residential area, the parking spaces have also been approved in this way. Well, we are in Rhineland-Palatinate, maybe it is different here.

We are planning it that way as well.

Regarding parking spaces, I would simply ask the city or municipality. They are the ones who decide in the end. It has nothing to do with the federal state and can be different in each place. Here in our town, there are many parking spaces from which you have to back out onto the street. We were just approved like that as well.

On the topic of parking spaces in a row. I have found no prohibition against placing parking spaces in a row either in Paragraph 12 of the Baunutzungsverordnung or in our development plan. In the other new development area, the parking spaces were also approved this way. Well, we are in Rhineland-Palatinate, maybe it is different here.

We are planning it that way as well.

Yes, to my knowledge, this would be state law.
A parked parking space is not a fully valid parking space. If you only have to provide one, then it is up to you to build another 5 in a row, since the one required is approved.
However, in my opinion, there are many liberties that one may build which make no sense at all, and a parked parking space with one required vehicle is indeed a nuisance if you do not master Tetris.

Clearly the wrong approach. If you already have a tricky plot, the house must be designed for the plot and not that you buy a house and somehow force it in. Even moving walls hardly helps.

130 sqm without a basement for four people is already quite tight. A standard layout is then not acceptable.

Next time I would do it differently, now it can't be changed. But I don't think the plot and the house are that bad.

Not 10 in width.

But to be honest, I also have to say that I can’t handle the sketch and apparently roughly estimated measurements on the house (9.51 is not 10) to give tips or advice. I also can’t see a difference for exterior walls at 49 cm. Especially if you don’t have much to work with or the plot explains its limits for a normal single-family house, you have to refine the design to 10 cm, be open to possibilities, but also plan buffer spaces: plaster thickness up to garden fence, aisles in the bedroom and dressing room ... according to your information, even dressing room and bedroom would not work for me here...

Then just say which house, which provider it is.

Flair134, the dimensions are practically traced 1:1 from the original floor plan. There may be minimal deviations. Interior dimension is 9.52 m with 10 m exterior dimension. A 1 cm error on 10 m is 0.1%, neither laser measure nor tape measure can do better than that ;).

Then you should first plan 10 cm for a fence and another meter for a hedge... nothing can be planned precisely with your computer sketch nor does the viewer get a feeling for the plot size. That also applies to the owner and planner.
Also, a vehicle does not measure the same width as a carport, so you should also plan a path between car and house...

The site plan is drawn to scale pixel-perfect, parking space each 3x5 m which corresponds to usual dimensions of a single carport.

Of course, there is still a garden!

In the last site plan, there is 13x18.8 m garden remaining from the house edge with 5 m front yard.
How far north would you retreat and why?

At the moment I only see a big annoyance and planning failure regarding the fleet of vehicles, which due to frequency, duration, and thus limited use of the plot will lead to much dissatisfaction. The resale value will also decrease because of this...

Siteplan_new2 is to scale. I thank you in advance for a more skillful suggestion.

The site plan is drawn to scale with pixel accuracy,

Pixel accurate it may be, but it is not a site plan: you only see the layout of the house, parking spaces, etc. on the property, but NOTHING of the location of the property within the plot. So zero recognizability of a reference to the street, neighboring properties, GFL corridors, and so on. You can’t work with that.
