Is a development plan required for obtaining offers?

How many meters does the property have at the front now? One drawing shows 12 m, the other 16 m. That is a significant difference, because I would also try to move further forward. This would actually be quite feasible with 16 m and then agreed boundary construction.

The house could also stand diagonally in the front part, so you waste a lot of the property.

By image format, do you really mean the block sheet drawings?

Mainly .jpg or .png instead of the PDFs, which are probably more cumbersome for the discussants using mobile devices.

I wasn't aware of the widths of the walls,

Very roughly standardized: exterior walls about 40 cm each, 20 cm for a load-bearing wall, and 10 cm for a non-load-bearing wall, making a meter ten. Mainly, you have to consider this for the space requirements, but if you have three small rooms on one side and only one large room on the other, you also have to take into account the "shifts" in the overall dimensions caused by the interior walls.

13m - The problem is less the width than the angle. But you can also place the carport at an angle. Don’t worry! It can still look great! If your neighbor is a relative(?), would a boundary construction be conceivable? Something like back to back or side by side of the garages.

Boundary construction is definitely feasible. As I said, it’s my brother who is building next to me. :) But unfortunately, I can’t quite imagine what exactly you mean by placing it slanted in the front.

It is 12 m, the drawing on the block was the first sketch just according to ruler measurement from the surveying office. The 12 meters are from the Bayernatlas, so somewhat more accurate... a few cm more or less

The house could also stand diagonally in the front part, so you waste a lot of the property.

I can hardly imagine that either, I'm somehow too unimaginative :(

I passed it on to my better half, maybe it's doable. He did all of that, I'm not particularly talented.

Roughly speaking, exterior walls about 40 cm each, 20 cm for a load-bearing wall and 10 cm for a non-load-bearing wall, that makes one meter ten. Mainly you have to consider that for the space requirements, but if you have three small rooms on one side and only one large one on the other, then you also have to take into account the "shifts" of the overall dimensions caused by the interior walls.

Great, it's noted with me. I'll pass it on as well and hope he can plan it accordingly. Or rather, he has to. :D

and hope he can schedule it accordingly.

No, as long as we consider lines as "walls", just keep the sum of the measurements in mind for now. So 4 + 3 + 4 m are not 11 m, but 12.20 m.
