[A GARAGE WITH A WIDTH OF 3M IS ALREADY NOT VERY GENEROUS, BUT 2.8M IS A STATEMENT. INSIDE YOU WILL NOT HAVE MORE THAN 2.6M. I WOULD ADVISE YOU TO TEST THIS. I FIND THE DISTANCE BETWEEN HOUSE AND GARAGE A BIT STRANGE, BECAUSE WITH THE SMALL DISTANCE YOU WON'T GET MUCH LIGHT INTO THE HOUSE, AS A PASSAGE IT IS ALMOST TOO NARROW AND THIS WIDTH IS MISSING IN THE GARAGE.
HOW DID YOU IMAGINE ACCESS TO THE HOUSE? FORWARD THROUGH THE 2.75M "TUNNEL" I CAN STILL IMAGINE, BUT HOW DO YOU GET BACK FROM THE PROPERTY? REVERSE OUT I FIND INTERESTING. TURNING IN FRONT OF THE HOUSE?]
I probably didn’t explain that well enough: the one in the plan is a carport originally planned by the architect, but we do not want to realize it like that for exactly the reasons you mentioned. Instead, we want to build a garage across the entire width as drawn in the plan sketch (at the very top in the 1st post).
Regarding the driveway: yes, that is a problem we have already thought about. Maybe we are lucky, because for the front house a parking space also has to be realized, and it is most likely planned directly at our boundary. So we could possibly use that space for turning if two cars would fit on the 12 m width:
