The access road is really lousy and a 9m garage is quite a solid wall. Even if you orient the terrace to the west, you’ll only get sun there if the garage actually moves to the other end of the driveway. That’s going to be quite a challenge for the driveway. But honestly, I would probably do it – I’m a worshiper of light.
Maybe like this:
Or if you’re a bit bolder, then like this:
(House dimensions are just for orientation and do not claim to be meaningful.)
Garage at the front towards the driveway.
Possibly at the west boundary or in the south next to the neighbor’s garage
Garage in the west and around the corner – you have to see that you can make the “turn.” Could be tight. Is there already someone who knows the space requirement for a 90° turn?
To the south would be a shame. Then you have neither south nor west sun on the terrace. The plot is too small for that.
