Corner plot with a granny flat

On the other hand: those who can, are also happy to be outside up to the garden fence. However, I don't believe the situation will ease:

If possible, then yes. I also have no solution at hand, just wanted to question so-called "must-haves" that might stand in the way of a solution elsewhere. Actually, living together is nice but also a burden on both sides, which must be clarified bindingly beforehand, as long as you haven’t lived together yet. Ultimately, it depends on so many individual details that you can’t foresee beforehand. Surely, we sometimes annoyed our parents because we did it differently. When you have to see it directly, it is different than when you live 500m away. I also wouldn’t have thought that I would dislike the upstairs roof terrace above ours or the same house entrance. There is social control or it is sometimes perceived as such, even if it doesn’t actually exist, even if you like each other very much.

I like the entrance area, but unfortunately it might not be possible to have the entrance and garden on the same side

So, moving on. What does the planting specification look like now regarding the front garden? Point 7.7 Because this is also decisive regarding possible parking spaces.

2 per residential unit

If we take that literally, 3 would be necessary for your construction project.

Now you write 2 per residential unit. That makes a difference.

I don't want to complicate things here. It's just that what you need, what you must, and what you think you must or are allowed to do are different things.

Yes, sorry. According to the statute, 4 would be necessary. (but they can be bought off quite cheaply)
My wish, however, would be the garage + driveway + 2 separate parking spaces. I just don't see how to fit 2 garages there.

So, moving on.

The planting requirement is strict—exact plants to choose from and also regarding sealed surfaces.

I have to look it up again right away.

I tinkered around a bit. I changed the orientation of the granny flat and the main house several times but ended up returning to my original idea of placing the granny flat to the east. I would have actually liked to relate the carport/garage more to the main house. As it stands, they are more associated with the granny flat. Here is the result, also regarding the use of the front garden and parking spaces. Whether to build a garage or leave it as a carport, or put a different roof on it... as you wish. But now everyone has their own area. Outdoors, the granny flat is sectioned off so that raised beds for the family can be created behind it. I struggled with the upper floor. Very likely, there are different and better ways. Maybe the utility room should be moved to the outer wall, so some more tinkering would be necessary... I’m still sharing it here because maybe further ideas will emerge.

Wow, I'm impressed. That's something completely different. The carport/house corner won't be exactly cheap... I scribbled with a pencil and tried again to fit everything into 12x12m. But I always get stuck with the long hallway. I also think the granny flat has to be in the east. But I would like the dining area/kitchen more towards the "garden."

So, weiter. Wie sieht denn jetzt die Pflanzvorgabe hinsichtlich des Vorgartens aus? Punkt 7.7 Denn das ist ja auch ausschlaggebend hinsichtlich möglicher Stellplätze.
