What would you take instead of 9x10?
No 10 in width. But to be honest, I also have to say that I can’t deal with the line drawing and apparently rough, estimated dimensions of the house (9.51 is not 10) to give tips or advice. I also can’t see a difference for exterior walls at 49cm. Especially when you don’t have much space available or the plot’s limitations explain its finiteness for a normal single-family house, you have to refine the design very precisely to 10cm, be open to possibilities, but also plan buffer zones: plaster thickness up to garden fence, corridors in bedroom and dressing room... according to your information, for me, even a dressing room and bedroom wouldn’t work here...
adapted catalog house
Then please say which house and which provider it is.
Two parking spaces side by side would be ideal, but I would rather not take the risk of ending up 3 cm too close to the neighbor.
Then you should first plan 10cm for a fence and another meter for a hedge... with your computer line drawing, nothing can be planned precisely and the viewer does not get a sense of the plot size. This also applies to the owner and planner. A vehicle also does not measure the same width as a carport, so you should also plan a path between car and house...
The pantry is more than a walk-in built-in closet
Then a closet is probably enough, saving you the search between utility room and pantry.
If we push the house further north, unfortunately there won’t be much garden left.
Of course there will be garden!
We currently also have two spaces one behind the other in the same town, seems to work.
Appearance or semblance is not approved, customary rights are not approved, nor are two parking spaces without turning possibility with hammerhead access at all worth discussing. I strongly advise you to buy graph paper tomorrow and accurately redraw the house with a pencil. 1 millimeter = 10 cm, this then also includes interior walls or about 2 mm for load-bearing walls. And then exact dimensions including outdoor areas, parking spaces, turning circle. At the moment, I only see a major frustration and misplanning regarding the vehicle fleet, which will lead to much displeasure due to frequency, duration, and thus reduced use of the plot. The resale value will also decrease because of this... Meanwhile, as already mentioned, you show the original design.
