Canopy between prefabricated garage and house

hello,

I want to build a parking space for myself.
I have a semi-detached house, 5m away from it stands my prefabricated garage.
Now I want to roof the space in between.
I don’t want to use support beams but rather span the 5m freely.
Can someone give me tips on how to accomplish this most easily?
The house has 8cm full thermal insulation, how can I attach the wooden beams to it?

regards
dieter

why don't you just want to put a support beam in between?

I would just like to have some space so that I can still drive through.
That's why no supports in between.

Is there any objection to resting it on the garage?
