I am missing the classification of the property in the surroundings, meaning, what is going on in the north, east, west ... maybe a general site plan.
And, I would rather orient the terrace towards the southwest ... here is an example:
The yellow overlay is meant to demonstrate the south sun. The advantage here would be that especially in summer the west sun can still be used well. And at least in summer the east sun also has a chance to cast a few rays between the house and the garage.
House about 3 m away from the street towards the bottom of the plan
