I think placing the house and garage in the south is nonsense. Towards the southeast, you have a nice open view and a great orientation for the garden. I would be cautious about orienting the house and garden to the west. Probably the shadow of the neighboring house is always there, and the sun only comes onto your property in front of and behind the neighbor. But just take a look at it. However, it is midsummer now, one must not forget that!
I would definitely place the house as far north as possible. The double carport means that your house must maintain a distance of 5-6 m from the boundary. Entrance from the north (then the carport must be further west) or, if possible, from the east.
